Abstract
A diagnostic apparatus for diagnosing the circulatory system of a patient, including an X-ray diagnostic system and an ultrasonic diagnostic system. The ultrasonic diagnostic system has an ultrasonic catheter for insertion into the circulatory systems of the patient and for scanning a circulatory organ with an ultrasonic wave to thereby an ultrasonic tomogram. A roadmap image is obtained prior to the ultrasonic diagnosis. When the ultrasonic catheter is inserted into the circulatory system of the patient, the X-ray diagnosis is performed to obtain a live image of the circulatory system which includes a picture of the catheter and is displayed overlapped on the roadmap image. The ultrasonic catheter is inserted into the circulatory system of the patient while the location of the catheter is monitored from the overlapped display of the live image and the roadmap image.
