Ultrasonic diagnostic apparatus
First Claim
1. An ultrasonic diagnostic apparatus for observing an ultrasonic tomographic image of a bodily portion of a patient,:
- an insertion section which is insertable into a cavity of the body of the patient and having a distal end and a proximal end;
an optical observation means for observing an optical image of said bodily portion of the patient, said optical means including an objective lens system arranged at the distal end of the insertion section and defining an observation field;
an ultrasonic observation means for observing an ultrasonic tomographic image of said bodily portion of the patient and having an ultrasonic vibrating element arranged within the distal end of the insertion section;
a display means electrically coupled with said ultrasonic vibrating element and having a display screen for displaying the ultrasonic tomographic image of said bodily portion of the patient;
means for obtaining a direction indicator representing a predetermined positional relationship between the ultrasonic tomographic image and the optical image; and
a display controlling means for displaying said direction indicator in a superposed manner with the ultrasonic tomographic image displayed on the display screen of the displaying means.

Abstract
An ultrasonic diagnosing apparatus having an ultrasonic observation system for observing an ultrasonic tomographic image of a portion of a body of patient and an optical observation system for observing an optical image of the portion, a direction indicator is superimposed on an ultrasonic tomographic image displayed on a monitor screen, and the direction indicator is rotated on the monitor screen in accordance with the rotation of the ultrasonic tomographic image. The ultrasonic diagnosing apparatus further has a system for compensating for a deviation between the ultrasonic tomographic image displayed on the monitor screen and the optical image due to a twist of a flexible shaft which is extended in an insertion section of the apparatus to rotate an ultrasonic vibrating element arranged in a distal end of the insertion section.

14. An ultrasonic diagnostic apparatus for observing an ultrasonic tomographic image of a bodily portion of a patient, comprising:
-
an insertion section which is insertable into a cavity of the body of the patient and having a distal end and a proximal end and a bending section arranged near the distal end; an ultrasonic observation means for observing an ultrasonic tomographic image of said bodily portion of the patient and having an ultrasonic vibrating element arranged within the distal end of the insertion section; a display means electrically coupled with said ultrasonic vibrating element for receiving an echo signal supplied form the ultrasonic vibrating element to produce a video signal and including a display screen for displaying the ultrasonic tomographic image of said bodily portion of the patient; a twist detecting means for detecting one of (i) an amount of and (ii) an amount and a direction of the bending moment of the bending section of the insertion section to produce a twist detection signal; and a display controlling means for receiving the twist detection signal and rotating the ultrasonic tomographic image displayed on the display screen of the displaying means in accordance with the twist detection signal. - View Dependent Claims (15, 16, 17, 18)
