Abstract
An ultrasound diagnostic apparatus (1) includes a time phase search period specifying unit (16) that specifies a time phase search period in each heartbeat period on the basis of Doppler data; and a frame specifying unit (12) that specifies at least one of B-mode data of a frame with a maximum diameter of a blood vessel or B-mode data of a frame with a minimum diameter of the blood vessel in each heartbeat period by analyzing the B-mode data of a plurality of frames in the time phase search period specified by the time phase search period specifying unit (16).
Claims20
An ultrasound diagnostic apparatus in which B-mode data and Doppler data of a region including a blood vessel of a subject are continuously acquired for a predetermined period, the ultrasound diagnostic apparatus comprising:
- a processor configured to
- specify a time phase search period in each heartbeat period on the basis of the Doppler data, and
- specify at least one of the B-mode data of a frame with a maximum diameter of the blood vessel or the B-mode data of a frame with a minimum diameter of the blood vessel in each heartbeat period by analyzing the B-mode data of a plurality of frames in the time phase search period.
A control method of an ultrasound diagnostic apparatus in which B-mode data and Doppler data of a region including a blood vessel of a subject are continuously acquired for a predetermined period, the control method comprising:
- specifying a time phase search period in each heartbeat period on the basis of the Doppler data;
- and
- specifying at least one of the B-mode data of a frame with a maximum diameter of the blood vessel or the B-mode data of a frame with a minimum diameter of the blood vessel in each heartbeat period by analyzing the B-mode data of a plurality of frames in the specified time phase search period.
A processor for an ultrasound diagnostic apparatus comprising:
- acquiring B-mode data and Doppler data of a region including a blood vessel of a subject continuously for a predetermined period;
- specifying a time phase search period in each heartbeat period on the basis of the Doppler data;
- and
- specifying at least one of the B-mode data of a frame with a maximum diameter of the blood vessel or the B-mode data of a frame with a minimum diameter of the blood vessel in each heartbeat period by analyzing the B-mode data of a plurality of frames in the specified time phase search period.
