Technical Field

Certain embodiments relate to a truss aperture. More particularly, certain embodiments relate to methods and systems for providing fluid-cooled variable-size truss bores.

Background

As part of the diagnostic procedure, medical imaging machines are sometimes used to image at least a portion of a patient's body. The imaging machine may be, for example, a Positron Emission Tomography (PET) scanner, a single photon emission tomography scanner, or the like, as well as hybrid imaging machines of the above-described technologies. The patient may be placed on the couch, and the couch may be moved into position through the holes of the truss of the imaging machine so that the imaging machine can make appropriate images of the patient. The imaging machine may be provided with trusses of different sizes, depending on the needs of the imaging machine. For example, if the imaging machine is intended for a pediatric hospital, the bore of the imaging machine may be smaller than if the imaging machine is intended for a hospital that attends all patients (including adults). The number of detectors used in a PET scanner may vary depending on the size of the truss aperture. Thus, for smaller bore PET scanners, the cost of the PET scanner may be lower.

Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present disclosure as set forth in the remainder of the present application with reference to the drawings.

Detailed Description

Certain embodiments may be found in methods and systems for variable size truss holes for fluid cooling.

The foregoing summary, as well as the following detailed description of certain embodiments, will be better understood when read in conjunction with the appended drawings. To the extent that the figures illustrate diagrams of the functional blocks of various embodiments, the functional blocks are not necessarily indicative of the division between mechanical components and/or hardware circuitry. The fluid used for cooling may be a liquid or a gas.

It should be understood that the various embodiments are not limited to the arrangements and instrumentality shown in the drawings. It is to be further understood that the embodiments may be combined, or that other embodiments may be utilized and that structural, logical, and electrical changes may be made without departing from the scope of the various embodiments. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims and their equivalents.

As used herein, an element or step recited in the singular and proceeded with the word "a" or "an" should be understood as not excluding plural said elements or steps, unless such exclusion is explicitly recited. Furthermore, references to "exemplary embodiments," "various embodiments," "certain embodiments," "representative embodiments," etc., are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Furthermore, unless explicitly stated to the contrary, embodiments "comprising," "including," or "having" an element or a plurality of elements having a particular property may include additional elements not having that property.

Also as used herein, the term "imaging machine" broadly refers to a PET scanner, a CAT scanner, an MRI scanner, or any other medical imaging machine capable of scanning at least a portion of a patient.

Fig. 1 is a schematic diagram of an exemplary PET scanner, according to various embodiments. Referring to fig. 1, a PET scanner 100 is shown that includes a truss 102, a truss bore 104, a patient bed 106, and a bed base 108. A patient may lie on the patient bed 106 and the patient bed 106 may be moved into the truss 102 through the truss apertures 104 so that the PET scanner 100 may capture images of the patient. A bed base 108 attached to patient bed 106 may move the patient bed into truss 102 or out of truss 102.

As shown in fig. 2A-7B, internal to the truss 102 is a truss mechanism, which may include a truss structure, an adapter plate removably mounted to the truss structure, and a PET detector removably mounted to the adapter plate.

Fig. 2A is an illustration of an exemplary PET scanner truss structure with detectors, in accordance with various embodiments. Referring to fig. 2A, a truss mechanism 200 is shown that includes a truss structure 202, an adapter plate 204, and a PET detector 206. The truss mechanism 200 may be used with the PET scanner 100.

There may be multiple adapter plates 204 for selection by the truss mechanism 200, where each adapter plate 204 may have a different aperture (opening) size. An appropriate adapter board 204 may be used for a particular purpose. For example, when the PET scanner 100 is used with children, the adapter plates 204 with small pore sizes may be ordered. The PET scanner 100 may also use different adapter boards 204 in different regions of the world where adult patients may differ in size.

When the adapter plate 204 is selected, the number of PET detectors 206 removably coupled to the adapter plate 204 may vary depending on the aperture size of the adapter plate 204. Thus, when the PET scanner 100 is sequenced, fewer PET detectors 206 may be required using a smaller adapter board 204 than using a larger adapter board 204. Using fewer PET detectors 206 may result in a less expensive finished PET scanner 100.

The adapter plate 204 may be removably coupled to the truss structure 202 using, for example, bolts. Thus, the adapter plate 204 may have holes into which bolts may be inserted to screw into corresponding threaded holes in, for example, the truss structure 202. In some embodiments, the adapter plate 204 may also have threaded bolt holes. Each of the PET detectors 206 is removably coupled to the adapter plate 204. For example, each of the PET detectors 206 may be removably coupled to the adapter plate 204 using, for example, bolts, wherein holes in the adapter plate 204 and/or corresponding holes in the PET detectors 206 may be threaded.

Various embodiments may have supports (not shown) on the adapter plate 204 to align the PET detectors 206. Other implementations may allow the PET detector 206 to be aligned with the PET detector 206 on either side. For example, each PET detector 206 may have a notch (not shown) on a first side and a corresponding tab (not shown) on a second side, such that the tab of a first PET detector 206 may fit into the notch of a second PET detector 206, and so on.

Fig. 2B is an exploded view of an exemplary PET scanner truss structure with the detectors of fig. 2A, in accordance with various embodiments. Referring to FIG. 2B, a truss mechanism 200 is shown that includes a truss structure 202, an adapter plate 204, and a PET detector 206. The truss mechanism 200 may be used with the PET scanner 100. A cooling liquid manifold 208 is also shown. The cooling liquid manifold may be used, for example, in a liquid cooled PET scanner truss structure with detectors. This will be described in more detail with respect to fig. 7A and 7B.

Fig. 3A is a schematic diagram of another exemplary PET scanner truss structure with detectors, in accordance with various embodiments. Exemplary truss mechanism 300 may be similar to truss mechanism 200, but truss mechanism 300 may include a PET detector 306B in addition to PET detector 206 shown in fig. 2A and 2B. Thus, there may be PET detectors removably coupled to both sides of the adapter plate 304 in fig. 3A. Additionally, a second cooling liquid manifold 208 may be present to cool a second set of PET detectors 306B.

Fig. 3B is an exploded view of an exemplary PET scanner truss structure with the detectors of fig. 3A, in accordance with various embodiments. Referring to FIG. 3B, a truss mechanism 300 is shown that includes a truss structure 302, an adapter plate 304, PET detectors 306A and 306B, and cooling liquid manifolds 308A and 308B. The truss mechanism 300 may be used with the PET scanner 100.

Adapter plate 304 may be removably coupled to truss structure 302, and PET detectors 306A and 306B may be removably coupled to truss structure 302, similar to that described with respect to fig. 2A and 2B.

Fig. 4 is a cross-section of a side view of an exemplary PET scanner truss structure with the detectors of fig. 3A, in accordance with various embodiments. Referring to FIG. 4, a truss mechanism 400 is shown that includes a truss structure 402, an adapter plate 404, PET detectors 406A and 406B, and cooling liquid manifolds 408A and 408B.

Fig. 5 is an illustration of an exemplary air-cooled PET scanner truss structure with detectors, in accordance with various embodiments. Referring to fig. 5, a truss mechanism 500 is shown that is air cooled by a blower 510, wherein air from the blower 510 may be provided to an air intake manifold 514 via an air conduit 512. Air provided to the inlet manifold 514 may be blown over the PET detectors 506 to cool the PET detectors 506.

The air inlet manifold 514 may be located at a first end of the PET detector 506 that is removably coupled to the adapter plate 504 or at a second end of the PET detector 506 that is not coupled to the adapter plate 504. The adapter plate 504 may have holes (not shown) to allow air to enter that flows over the PET detectors 506 or to allow air to flow out that flows over the PET detectors 506.

In various embodiments, the blower 510 may be, for example, an air conditioner that cools air prior to providing the cooled air to the intake manifold 514.

Fig. 6 is a cross-sectional view of an exemplary air-cooled PET scanner truss structure with the detectors of fig. 5, in accordance with various embodiments. Referring to FIG. 6, a truss mechanism 600 is shown in which air from an air inlet manifold 614 flows over the PET detectors 606 via conduits 616 to cool the PET detectors 606. The air may then exit via air outlets 622 in the air outlet manifold 620. It should be noted that the conduit 616 may be an open area above the PET detector 606. However, some embodiments may include a closed conduit, which may be in the form of a tube extending at least a portion of the distance from the gas inlet manifold 614 to the gas outlet manifold 620.

Fig. 7A is a cross-section of a side view of an exemplary liquid-cooled PET scanner truss structure with detectors, in accordance with various embodiments. Referring to FIG. 7A, a truss mechanism 700 is shown that includes a truss structure 702, PET detectors 706A and 706B, an adapter plate 704 with cooling liquid coils 713, and holding structures 711A and 711B.

Retention structures 711A and 711B may be coupled to PET detectors 706A and 706B and to adapter plate 704. The coupling may be a removable coupling using, for example, mechanical means such as bolts and/or nuts. The coupling may also be a removable coupling using, for example, a thermally conductive adhesive. In some embodiments, chemicals may be used to loosen the adhesive.

The retention structures 711A and 711B may act as heat sinks to transfer heat from the PET detectors 706A and 706B to the adapter board 704. Accordingly, retention structures 706A and 706B may encircle PET detectors 706A and 706B. The retaining structures 706A and 706B may be solid structures or may include fins for further dissipating heat from the PET detectors 706A and 706B. The adapter board 704 may have a cooling liquid coil 713 for removing heat from the adapter board 704. The liquid in the cooling liquid coil 713 may be pumped by a pump (not shown).

In some embodiments, liquid may be pumped into the cooling liquid coil 713, and the discharged liquid exiting the cooling liquid coil 713 may not be reused. In other embodiments, the drained liquid may be held in a holding tank (not shown), for example, for reuse at a later time after the liquid has cooled. In other embodiments, the liquid may be cooled, for example, because the refrigerant may be cooled for a refrigerator and then pumped back to the adapter board 704. Thus, the liquid may be any of a number of different types of liquids that may be used for cooling. For example, the liquid may be water or some aqueous solution, or a suitable refrigerant.

While the cross-sectional view of the adapter plate 704 shows four conduits, various examples of the present disclosure may have more or fewer conduits shown in cross-section. Additionally, while the cooling liquid coils 713 are shown as being centered in the adapter plate 704, various embodiments may have the cooling liquid coils 713 offset to one side or the other. For example, a first coil may be offset to be closer to the retention structure 711A, and a second coil may be offset to be closer to the retention structure 711b, and so on.

Fig. 7B is a cross-section of a side view of another exemplary liquid-cooled PET scanner truss structure with detectors, in accordance with various embodiments. Referring to fig. 7B, a similar configuration to fig. 7A is shown, except that the cooling liquid coils 713 of fig. 7A are shown in external cooling structures 715A and 715B, in which the cooling liquid coils 713A and 713B are placed, respectively.

It should be noted that for fig. 7A and 7B, when there is only one set of PET detectors 706A, there may be only one holding structure 711A, and in the case of fig. 7B, there may be only one external cooling structure 715A.

Thus, it can be seen that the present disclosure provides an imaging system 100 having an adapter plate 304 configured to be removably coupled to a truss structure 302 of the imaging system, a plurality of detectors 306A and 306B configured to be removably coupled to the adapter plate 304, and one or more conduits 713 or 616 for a fluid to flow through, wherein the fluid is used to cool the imaging system. The fluid may be air (gas) or liquid.

The adapter plate 304 may be one of several different sizes of adapter plates, with the particular size of the adapter plate being selected based on the desired truss bore size. At least two of the different sized adapter plates may be configured to be removably attached to different respective numbers of detectors. Thus, adapter plates with smaller truss bore sizes may use fewer detectors, thereby reducing the cost of the imaging system.

The detectors may be removably attached to both sides of the adapter plate. In one embodiment, the imaging system may be configured to allow air to flow through the one or more conduits 616, and the one or more conduits 616 may be configured to carry air over the plurality of detectors 606 to help cool the detectors. In some embodiments, the air may be cooled prior to being provided to the one or more conduits.

There may be at least one air inlet manifold 614, wherein air is provided to one or more conduits 616 via the at least one air inlet manifold 614. There may also be at least one air outlet manifold 620, wherein the at least one air outlet manifold 620 may receive air from at least one of the one or more conduits 616.

In one embodiment, the imaging system 100 may be configured to allow liquid to flow through one or more conduits, where the conduit 713 may be located in the adapter plate 704. The catheter may form at least one coil 713 in the adapter board 704. In another embodiment, one or more conduits may include at least one coil 713A/713B located outside of the adapter board 704. For example, there may be at least one coil 713A/713B on each side of the adapter board 704. The liquid may be cooled before being provided to the one or more conduits.

It can also be seen that the present disclosure provides the air-cooled imaging system of fig. 5 and 6, comprising: an adapter plate 504, which may be one of a plurality of different sized adapter plates, configured to be removably coupled to the truss structure 502 of the imaging system 100; a plurality of detectors 506 configured to be removably coupled to the adapter plate 504; and one or more conduits 616 through which air flows, wherein the air is used to cool the imaging system 100. The one or more conduits 616 are configured to carry air over the plurality of detectors 606. At least two of the different sized adapter plates are configured to be removably attached to different respective numbers of detectors 606.

In addition, the present disclosure also provides the liquid-cooled imaging system of fig. 7A and 7B, comprising: an adapter plate 704, which may be one of a plurality of different sized adapter plates, configured to be removably coupled to the truss structure 702 of the imaging system 100; a plurality of detectors 706A/706B configured to be removably coupled to the adapter plate 704; and one or more conduits 713/713a/713B for flowing a liquid, wherein the liquid is used to cool the imaging system. The one or more conduits include one or both of: at least one coil 713A/713B located outside the adapter board 704, and at least one coil 713 located in the adapter board 704. At least two of the different sized adapter boards are configured to be removably attached to different respective numbers of detectors 706A/706B.
