ULTRASONIC DIAGNOSTIC APPARATUS AND PROGRAM THEREFOR

摘要

To provide an ultrasonic diagnostic apparatus enabling one to easily know the correspondence between a needle in an ultrasonic image and an actual needle. An ultrasonic diagnostic apparatus 1 comprises: a first position detecting section for detecting information on a position of a needle N inserted into a subject; an operating section 7 for accepting from a user inputs for, for a plurality of needles N inserted into the subject, appending distinguishing information for distinguishing each of the plurality of needles and storing information on a position detected by the first position detecting section for a needle appended with the distinguishing information; a second position detecting section for detecting information on a position of an ultrasound transmission/reception plane; and a display control section for displaying, in the case that a needle N whose information on a position is stored is included in the ultrasound transmission/reception plane, a marker indicating the needle in an ultrasonic image displayed in a display section for the transmission/reception plane in a manner that the needle is distinguishable from another needle based on the distinguishing information.

1. An ultrasonic diagnostic apparatus characterized in comprising:
a first position detecting section for detecting information on a position of a needle inserted into a subject in a specified coordinate system in a three-dimensional (3D) space; an input section for accepting from a user inputs for, for a plurality of needles inserted into said subject, appending distinguishing information for distinguishing each of said plurality of needles and storing information on a position detected by said first position detecting section for a needle appended with said distinguishing information; a second position detecting section for detecting information on a position in said 3D space of an ultrasound transmission/reception plane formed by an ultrasonic probe performing ultrasound transmission/reception to/from said subject; and a display control section for displaying, in the case that a needle whose information on a position is stored is included in said ultrasound transmission/reception plane whose information on a position is detected by said second position detecting section, a marker indicating said needle in an ultrasonic image displayed in a display section for said transmission/reception plane in a manner that said needle is distinguishable from another needle based on said distinguishing information.
