POSITION CONTROL DEVICE, POSITION CONTROL METHOD, AND ULTRASOUND IMAGING SYSTEM

A position control device includes a storage unit (37) that is configured to store a deviation in an (n-1)-th line when an ultrasonic probe unit (1) scans the (n-1)-th line of a surface of a sample before the ultrasonic probe unit moves to an n-th line, the deviation being between time from transmit...

Beschreibung
Zusammenfassung:	A position control device includes a storage unit (37) that is configured to store a deviation in an (n-1)-th line when an ultrasonic probe unit (1) scans the (n-1)-th line of a surface of a sample before the ultrasonic probe unit moves to an n-th line, the deviation being between time from transmitting an ultrasonic wave until a reflected wave is received and a reference time; and a processing unit (35) that is configured to determine a position of the ultrasonic probe unit (1) when the ultrasonic probe unit (1) scans the n-th line of the surface of the sample based on the deviation in the (n-1)-th line, and to calculate a deviation in the n-th line between time from transmitting an ultrasonic wave until a reflected wave is received and the reference time when the ultrasonic probe unit scans the n-th line of the surface of the sample. The processing unit (35) is configured to determine the position of the ultrasonic probe unit (1) in a direction perpendicular to the surface of the sample such that the deviation is zero.
