Ultrasonic diagnosing system
First Claim
1. An ultrasonic diagnostic apparatus which advances and returns a radial scanning ultrasonic vibrator in the living body of a subject and generates a plurality of time-series radial tomographic images in accordance with the advance and return, the ultrasonic diagnostic apparatus comprising:
- positional information detecting means which detects positional information of the radial scanning ultrasonic vibrator upon obtaining the radial tomographic image; and
route tomographic generating means which generates a route tomographic image along a route of the advance and return of the radial scanning ultrasonic vibrator based on the positional information obtained from the positional information detecting means and the plurality of the time-series radial tomographic images.

Abstract
An ultrasonic diagnostic apparatus has an ultrasonic endoscope, an ultrasonic observing portion, a position detecting unit, a monitor, a keyboard, and a mouse. Cross-sectional planes in parallel therewith are set to radial tomographic images, an intersecting line segment is obtained between a radial tomographic image and the cross-sectional plane, the intersecting line segments are combined, and a route tomographic image is generated. It is easily recognized how the lesion is spreading along the luminal portion during the examination by advancing and returning a radial scanning ultrasonic probe. Further, which part in the luminal portion is scanning during the examination can easily be recognized during the examination.
