Positron Emission Tomography (PET) is an advanced clinical examination imaging technique in the field of nuclear medicine. It is to take certain substances, generally necessary in the metabolism of biological life, such as: glucose, protein, nucleic acid, fatty acid, short-lived radionuclides (such as 18F, 11C, etc.) labeled with a label, when injected into a human body, the radionuclides release positrons during decay, and a positron travels from a few tenths of a millimeter to a few millimeters and encounters an electron to be annihilated, thereby generating a pair of photons with energy of 511KeV in opposite directions. This is a pair of photons captured by a highly sensitive camera and corrected for scatter and random information by a computer. By carrying out the same analysis processing on different positrons, a three-dimensional image of the aggregation condition in a living body can be obtained, thereby achieving the purpose of diagnosis.
A Computed Tomography (CT) apparatus typically includes a gantry, a couch, and a console for operation by a physician. One side of the frame is provided with a bulb tube, and the side opposite to the bulb tube is provided with a detector. The console is a computer device for controlling scanning, and the computer device is also used for receiving scanning data acquired by the detector, processing and reconstructing the data and finally forming a CT image. When CT is used for scanning, a patient lies on a scanning bed, the scanning bed sends the patient into the aperture of a stand, a bulb tube arranged on the stand emits X rays, the X rays penetrate through the patient and are received by a detector to form scanning data, the scanning data are transmitted to computer equipment, and the computer equipment carries out primary processing and image reconstruction on the scanning data to obtain a CT image.

The scanning system comprises a scanning device positioned in the shielding chamber, the scanning device surrounds to form a scanning cavity, and the scanning cavity is a containing part of an object to be scanned in the scanning process. The scanning system also includes a scanning bed located within the shielded room, and the scanning bed is movable along the scanning chamber. The object to be scanned is laid on the scanning bed, and the object to be scanned is carried by the scanning bed and transferred from the outside of the scanning device to the scanning cavity. Specifically, the scanning bed comprises a bed plate, and an object to be scanned is placed on the bed plate for image scanning. The bed board of the scanning bed can be of various types, and the type of the bed board can be selected according to the actual application scene. Generally, in order to improve the comfort of an object to be scanned, an arc bed plate is generally adopted; in the radiotherapy process, a flat bed plate is needed; and part of using scenes can be replaced by the small animal bed board for scientific research.
Before performing the scan, a scan bed image is first acquired to find the type of the scan bed from the scan bed image.

Preferably, the camera can be arranged right above the scanning bed, so that the scanning bed surface contour image can be acquired well.
It will be appreciated that when the camera is located within the scanning chamber, the scanning bed is moved from outside the scanning apparatus into the scanning chamber and reaches a predetermined scanning position before it is taken to capture an image of the bed surface profile. When the camera is arranged outside the scanning cavity, the shooting can be started outside the scanning device so as to acquire the scanning bed surface contour image.
The scanning bed surface contour image may be obtained by processing an image shot by a camera, and specifically, the image shot by the camera may be subjected to gray scale processing first, and then a frame is extracted by using an image gradient algorithm to obtain the scanning bed surface contour image.
In one embodiment, the acquiring a scanning bed image of a scanning system comprises:

Specifically, when the operator issues an acquisition command, the scanning system responds to the acquisition command and automatically adjusts the corresponding components of the scanning system to a preset position (e.g., the X-ray tube is adjusted to the 12 o ' clock position, or the 3 o ' clock position, or the 9 o ' clock position) to acquire the image of the bed spacer.

and determining the type of the scanning bed according to the electron density difference information.

CT scanning is a technique of reconstructing a tomographic image by combining a computer with X-rays and using the difference in attenuation coefficients of the X-rays in different regions of an object to be scanned to make the radiation signals received by a detector different. For the scanning bed positioning sheet image, the structure of the scanning bed is different due to different types of the scanning bed, for example, the structure of a flat bed and an arc bed is different. In addition, in order to distinguish the type of the scanning bed more obviously, a visible mark can be arranged on the bed board of the scanning bed, and the structure of the scanning bed can be changed through the visible mark, for example, a hollow structure is arranged. According to the method and the device, the X-ray penetrates through the scanning bed, and the ray attenuation coefficients corresponding to different scanning bed types are different, so that the type of the scanning bed can be determined according to the ray attenuation coefficient distribution difference in the scanning bed locating piece image.

And if the first scanning bed type is not consistent with the target scanning bed type corresponding to the scanning bed type, adjusting the parameters of the initial model to enable the first scanning bed type output by the deep learning model to be consistent with the target scanning bed type. And when any scanning bed image is input, the target scanning bed type corresponding to the scanning bed image can be obtained, and then the current initial model is determined to be a trained deep learning model. The scanning bed type corresponding to the scanning bed image can be output according to the input scanning bed image through the trained deep learning model.
