1. An ultrasonic thickness measurement device comprising:
an ultrasonic probe including eight or less ultrasonic elements each including a transmission element and a receiving element, the transmission element and the receiving element being the ultrasonic elements; and
a controller configured to determine a thickness of a target body tissue from tomographic image data of a body of a subject acquired based on received signals that is received by receiving elements of each of the ultrasonic elements, wherein
the tomographic image data is image data in which data of each of tomographic images of eight or less lines corresponding to the eight or less ultrasonic elements is arranged, along a depth direction from a skin surface of the body of the subject,
the thickness is determined from the tomographic image data that is acquired by arranging, in association with an arrangement of each of the eight or less ultrasonic elements, B-mode images generated from A-mode images, and
the A-mode images are generated by processing each of the received signals that is sequentially received by the eight or less ultrasonic elements.
