Title:
POSITION CONTROL DEVICE, POSITION CONTROL METHOD, AND ULTRASOUND IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/143134
Kind Code:
A1
Abstract:
The present invention comprises: a storage unit (37) that stores deviation when an ultrasound probe unit (1) scans an (n-1)th line of a sample surface, such deviation being in the (n-1)th line between a reference time period and a time period from sending an ultrasound wave until receiving a reflected wave, and such storage performed before moving the ultrasound probe unit to an n line; and a processing unit (35) that determines, on the basis of the deviation in the (n-1)th line, the position of the ultrasound probe unit (1) when the ultrasound probe unit (1) scans the nth line of the sample surface, and that calculates the deviation, when the ultrasound probe unit scans the nth line of the sample surface, in the nth line between a reference time period and a time period from sending an ultrasound wave until receiving a reflected wave. The processing unit (35) determines the position of the ultrasound probe unit (1) in the vertical direction relative to the sample surface so that the deviation is zero.
