Abstract:
An ultrasonic diagnostic apparatus for forming an ultrasonic tomogram based on an ultrasonic echo signal, comprising:an ultrasonic probe having an ultrasonic vibrator at a distal end portion thereof, the ultrasonic vibrator designed to be inserted in the celom, the ultrasonic probe which outputs the ultrasonic echo signal; an inserting shape detecting means which detects an inserting shape of the ultrasonic probe; an auxiliary-image forming means which forms an auxiliary image correlating the inserting shape obtained by the inserting shape detecting portion with the ultrasonic tomogram; an output means which outputs the ultrasonic tomogram and the auxiliary image to a display device so that they can be compared with each other; and a tomographic-plane position and direction detecting means which detects a position and a direction of a diagnostic plane obtained by the ultrasonic diagnostic apparatus, wherein the auxiliary-image forming means forms a tomographic plane marker indicating a position and a direction of the tomographic plane obtained by the tomographic-plane position and direction detecting means and which combines the tomographic plane marker and the inserting shape to form the auxiliary image.
