Technical Field

The present invention relates to an ultrasonic diagnostic apparatus and a method of controlling the ultrasonic diagnostic apparatus, and more particularly, to an ultrasonic diagnostic apparatus and a method of controlling the ultrasonic diagnostic apparatus that perform measurement relating to a part of a subject based on an ultrasonic image.

Background

Conventionally, an ultrasonic diagnostic apparatus is known as an apparatus for obtaining an image of the inside of a subject. An ultrasonic diagnostic apparatus generally includes an ultrasonic probe including a transducer array in which a plurality of transducers are arranged. In a state where the ultrasonic probe is brought into contact with the body surface of the subject, an ultrasonic beam is transmitted from the transducer array toward the inside of the subject, and an ultrasonic echo from the subject is received in the transducer array to acquire element data. The ultrasonic diagnostic apparatus also electrically processes the obtained element data to generate an ultrasonic image of the part of the subject.

Using the ultrasound image thus generated, the length, area, and the like of a portion of the subject included in the ultrasound image are usually measured. For example, patent document 1 discloses an ultrasonic diagnostic apparatus that performs measurement on a part of a subject using an ultrasonic image. The ultrasonic diagnostic apparatus arranges a mark for designating a measurement range at a set position on an ultrasonic image set by a user, and automatically performs measurement on a region designated by the mark.

Disclosure of Invention

Technical problem to be solved by the invention

Measurement values obtained by measuring a part of a subject are often used for diagnosis of the subject by a doctor or the like. Therefore, it is desirable that the measurement value related to the part of the subject is obtained by measurement in accordance with a predetermined reference, and for such measurement, a guideline defining a reference of a measurement position, a measurement method, and the like is generally known.

In the technique described in patent document 1, since it is not considered that a part of a subject is measured in accordance with a certain standard as defined in the guideline, an inaccurate value may be obtained as a measurement value for diagnosing the subject by a doctor or the like.

In addition, in general, users such as doctors and technicians often perform measurement of a region of a subject by manual operation while visually observing an ultrasonic image, and in particular, even when an inexperienced user performs measurement while referring to a guideline, measurement according to an accurate reference may not be easily performed, and an accurate measurement value may not be obtained. Further, when a user who does not know the original guideline measures a subject portion, the measurement is not performed based on an accurate reference, and thus an accurate measurement value may not be obtained.

The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide an ultrasonic diagnostic apparatus and a control method of the ultrasonic diagnostic apparatus, which can measure a site of a subject according to an accurate reference regardless of the skill of a user.

Means for solving the technical problem

In order to achieve the above object, an ultrasonic diagnostic apparatus according to the present invention includes: an image memory that stores ultrasound images of a plurality of frames that are consecutive in time series and that include a measurement target site of a subject to be measured; an operation section for a user to select one of the plurality of frames as a selection frame; a display unit for displaying the ultrasonic image of the selected frame; a measurement unit that performs measurement relating to a measurement target region of a subject based on an ultrasound image; a determination unit that determines whether the measurement performed by the measurement unit has succeeded or failed; and a display switching unit that displays the measurement result in the selected frame on the display unit when the determination unit determines that the measurement performed on the selected frame by the measurement unit has succeeded, and displays the measurement result in at least one peripheral frame and the ultrasonic image of at least one peripheral frame different from the selected frame in the plurality of frames stored in the image memory on the display unit when the determination unit determines that the measurement performed on the selected frame by the measurement unit has failed.

In the peripheral frames, the measurement result is not displayed for the frame in which the measurement failed.

The at least one peripheral frame may be a prescribed number of frames consecutive to the selected frame.

Alternatively, the at least one peripheral frame may be all frames except the selected frame among frames within one heartbeat period including the selected frame. The measurement target site may be a site that moves periodically by the respiration of the subject or a site that moves periodically by the pulsation of the subject.

Alternatively, the at least one peripheral frame may be all frames except the selected frame in the series of frames under measurement.

When the determination unit determines that the measurement of the selected frame has failed, the at least one peripheral frame may be a partial frame from a frame next to the selected frame in time series to a frame after the selected frame and first determined by the determination unit to have a successful measurement, or may be a partial frame from a frame after the selected frame and first determined by the determination unit to have a successful measurement to a frame before the selected frame in time series.

When the determination unit determines that the measurement of the selected frame has failed, the display switching unit may highlight the frame determined by the determination unit to have succeeded in the measurement in at least one peripheral frame.

Alternatively, when the determination unit determines that the measurement of the selected frame has failed, at least one of the peripheral frames may be a frame determined by the determination unit to have succeeded in the measurement.

When the determination unit determines that all of the measurements on the selected frame and at least one of the peripheral frames have failed, the display switching unit may notify the user of an error.

For example, when the measurement target site is an inferior vena cava, the measurement unit detects a right atrial boundary of the subject, specifies a measurement position located at a position defined by the detected right atrial boundary, and measures the diameter of the inferior vena cava at the specified measurement position, and the determination unit determines that the measurement has failed when the right atrial boundary is not detected or when the measurement position is not specified by the measurement unit.

The measurement result may include a measurement line for performing measurement on a measurement target site of the subject.

The control method of an ultrasonic diagnostic apparatus according to the present invention is characterized by storing ultrasonic images of a plurality of frames which are consecutive in time series and include a measurement target site of a subject to be measured, displaying the ultrasonic image of a selected frame selected by a user from the plurality of frames, performing measurement relating to the measurement target site of the subject based on the selected frame, determining whether the measurement has succeeded or failed with respect to the selected frame, displaying the measurement result in the selected frame and the ultrasonic image of the selected frame if it is determined that the measurement has succeeded with respect to the selected frame, and displaying the ultrasonic image of the selected frame, the ultrasonic image of at least one peripheral frame different from the selected frame in the plurality of frames, and the measurement result in the at least one peripheral frame if it is determined that the measurement has failed with respect to the selected frame.

Effects of the invention

According to the present invention, the present invention comprises: a determination unit that determines that the measurement by the measurement unit has succeeded; and a display switching unit that displays the measurement result in the selected frame on the display unit when the determination unit determines that the measurement performed on the selected frame by the measurement unit has succeeded, and displays the measurement result in at least one peripheral frame and the ultrasonic image of at least one peripheral frame different from the selected frame among the plurality of frames stored in the image memory on the display unit when the determination unit determines that the measurement performed on the selected frame by the measurement unit has failed.
