Abstract
Provided are an ultrasound imaging apparatus and a surgical operation support system for obtaining position information of a device outside an imaging area and presenting the position information to a user together with an ultrasound image. The surgical operation support system includes the ultrasound imaging apparatus, an ultrasonic source fixed to a therapeutic tool to be inserted into a subject body, a display device for displaying the ultrasound image and the position of the ultrasonic source. The ultrasound imaging apparatus is provided with a position estimator for estimating the position information of the ultrasonic source, and the position estimator analyzes a grating lobe artifact (false image) that is generated by the ultrasonic wave emitted from the ultrasonic source outside the imaging area, to estimate the position information of the ultrasonic source with respect to the imaging area.
