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).
Claims16
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:
- an ultrasound probe;
- a transmission and reception circuit configured to transmit an ultrasound beam to an inside of the subject via the ultrasound probe, and receive an ultrasound echo from the inside of the subject to generate reception data;
- and
- a processor configured to
- generate the B-mode data on the basis of the reception data generated by the transmission and reception circuit,
- specify at least one of a first period and a second period within each heartbeat period as a time phase search period, where each heartbeat period is composed of the first period, the second period, and a third period, the first period includes a time point at which the Doppler data has a minimum value, the second period includes a time point at which the Doppler data has a maximum value, the third period runs from an end of the second period to an end of each heartbeat period, and the first period, the second period, and the third period within any heartbeat period are different from each other,
- calculate a diameter of the blood vessel included in the B-mode data of each of a plurality of frames only in the specified time phase search period within each heartbeat period, 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 within each heartbeat period based on the diameters of the blood vessel calculated from the B-mode data of the plurality of frames in the specified 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:
- transmitting an ultrasound beam to an inside of the subject via an ultrasound probe and receiving an ultrasound echo from the inside of the subject to generate reception data;
- generating the B-mode data on the basis of the reception data;
- specifying at least one of a first period and a second period as a time phase search period within each heartbeat period, where each heartbeat period is composed of the first period, the second period, and a third period, the first period includes a time point at which the Doppler data has a minimum value, the second period includes a time point at which the Doppler data has a maximum value, the third period runs from an end of the second period to an end of each heartbeat period, and the first period, the second period, and the third period within any heartbeat period are different from each other;
- calculating a diameter of the blood vessel included in the B-mode data of each of a plurality of frames only in the specified time phase search period within each heartbeat period;
- 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 within each heartbeat period based on the diameters of the blood vessel calculated from the B-mode data of the plurality of frames in the specified time phase search period.
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:
- an ultrasound probe;

- and
- a processor configured to
- generate the B-mode data on the basis of the reception data generated by the transmission and reception circuit,
- specify at least one of a first period and a second period within each heartbeat period as a time phase search period, where a first period starts from a first time point at which the Doppler data has a minimum value and ends with a second time point at which the Doppler data has a maximum value within each heartbeat period, a second period starts from the second time point and ends with a third time point within each heartbeat period, the third period runs from an end of the second period to an end of each heart beat period, and the first period and the second period within any heartbeat period are different from each other,
- calculate a diameter of the blood vessel included in the B-mode data of each of a plurality of frames only in the specified time phase search period within each heartbeat period, 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 within each heartbeat period based on the diameters of the blood vessel calculated from the B-mode data of the plurality of frames in the specified time phase search period.
