## Abstract

An ultrasound diagnostic apparatus (1), which performs a compression test with respect to at least two points of a popliteal vein and a common femoral vein of a subject, includes an ultrasound probe (15), an image acquisition unit (8) that acquires an ultrasound image by transmitting an ultrasound beam toward the subject from the ultrasound probe (15), a vein detection unit (9) that detects the popliteal vein included in the ultrasound image, and an operation guiding unit (10) that guides a user, in a case where the compression test of the popliteal vein is performed, to operate the ultrasound probe such that the ultrasound probe (15) is positioned at a position in which only one popliteal vein is included in the ultrasound image based on the number of the popliteal veins detected by the vein detection unit (9).

## Claims

### Claim 1

A method of controlling an ultrasound diagnostic apparatus that performs a compression test with respect to at least two points of a popliteal vein and a common femoral vein of a subject, the method comprising:
transmitting an ultrasound beam toward a back of a knee of the subject from an ultrasound probe to acquire an ultrasound image;
detecting the popliteal vein included in the acquired ultrasound image;
guiding a user to operate the ultrasound probe to fix the position of the ultrasound probe in a case where the compression test of the popliteal vein is performed and only one popliteal vein is detected; and
guiding the user to move the ultrasound probe to an upper side of a back of a knee of the subject in a case where the compression test of the popliteal vein is performed and a plurality of popliteal veins are detected.

### Claim 2 (depends on 1)

The method of controlling an ultrasound diagnostic apparatus according to claim 1, further comprising:
determining whether a movement range of the ultrasound probe by the user from a point in time when the ultrasound probe is guided to be moved to an upper side of a back of a knee of the subject is within a predetermined range; and
guiding the user to move the ultrasound probe to the back of the knee of the subject in a case where the determination is made that the movement range of the ultrasound probe is beyond the predetermined movement range.

### Claim 3 (depends on 2)

The method of controlling an ultrasound diagnostic apparatus according to claim 2, further comprising:
determining that the movement range of the ultrasound probe is beyond the predetermined movement range in a case where the number of frames of a plurality of the acquired ultrasound images exceeds a predetermined number of frames from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee.

### Claim 4 (depends on 2)

The method of controlling an ultrasound diagnostic apparatus according to claim 2, further comprising:
determining that the movement range of the ultrasound probe is beyond the predetermined movement range in a case where an elapsed time from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee exceeds a predetermined time.

### Claim 5 (depends on 2)

The method of controlling an ultrasound diagnostic apparatus according to claim 2, further comprising:
estimating a movement distance of the ultrasound probe based on an acceleration of the ultrasound probe measured by an acceleration sensor included in the ultrasound probe; and
determining that the movement range of the ultrasound probe from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee is beyond the predetermined movement range in a case where the estimated movement distance of the ultrasound probe exceeds a predetermined distance.

### Claim 6 (depends on 1)

The method of controlling an ultrasound diagnostic apparatus according to claim 1, further comprising:
causing a display device to display operation guidance on the ultrasound probe for the user.

### Claim 7

A method of controlling an ultrasound diagnostic apparatus that performs a compression test with respect to at least two points of a popliteal vein and a common femoral vein of a subject, the method comprising:
transmitting an ultrasound beam toward a back of a knee of the subject from an ultrasound probe to acquire an ultrasound image;
detecting the popliteal vein included in the acquired ultrasound image;
guiding a user to move the ultrasound probe to an upper side of a back of a knee of the subject in a case where the compression test of the popliteal vein is performed;
determining whether a movement range of the ultrasound probe by the user from a point in time when the ultrasound probe is guided to be moved to an upper side of a back of a knee of the subject is within a predetermined range; and
guiding the user to move the ultrasound probe to the back of the knee of the subject in a case where the determination is made that the movement range of the ultrasound probe is beyond the predetermined movement range.

### Claim 8 (depends on 7)

The method of controlling an ultrasound diagnostic apparatus according to claim 7, further comprising:
determining that the movement range of the ultrasound probe is beyond the predetermined movement range in a case where the number of frames of a plurality of the acquired ultrasound images exceeds a predetermined number of frames from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee.

### Claim 9 (depends on 7)

The method of controlling an ultrasound diagnostic apparatus according to claim 7, further comprising:
determining that the movement range of the ultrasound probe is beyond the predetermined movement range in a case where an elapsed time from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee exceeds a predetermined time.

### Claim 10 (depends on 7)

The method of controlling an ultrasound diagnostic apparatus according to claim 7, further comprising:
estimating a movement distance of the ultrasound probe based on an acceleration of the ultrasound probe measured by an acceleration sensor included in the ultrasound probe; and
determining that the movement range of the ultrasound probe from a point in time when the operation of the ultrasound probe is guided such that the ultrasound probe is moved to an upper side of the back of the knee is beyond the predetermined movement range in a case where the estimated movement distance of the ultrasound probe exceeds a predetermined distance.

### Claim 11 (depends on 7)

The method of controlling an ultrasound diagnostic apparatus according to claim 7, further comprising:
causing a display device to display operation guidance on the ultrasound probe for the user.
