Document Type and Number:
Japanese Patent JP7125356
Kind Code:
B2
Abstract:
To display an area in which a reception signal contributes to a reconstruction image when the reception signal includes data in which measurement of an arrival time is difficult.SOLUTION: An ultrasonic wave is transmitted to a subject a plurality of times while changing transmission angles, and a reception signal is acquired that receives the ultrasonic wave penetrating through the subject with an ultrasonic element string for each transmission. The reception signal is compared with a reception signal acquired with ultrasonic elements respectively by transmitting/receiving an ultrasonic wave with the ultrasonic element string without disposing the subject, and a value indicating a degree of reliability of the reception signal is obtained for each ultrasonic element. By executing image reconstruction based on the value indicating a degree of reliability of the reception signal of each ultrasonic element for each reception, which is calculated by a degree-of-reliability calculation unit, a degree-of-reliability map indicating the distribution of the degree of reliability in a cross section of the subject is generated.SELECTED DRAWING: Figure 1
