Abstract

An ultrasonic diagnosing apparatus for displaying an ultrasonic image of an organ of a patient including an ultrasonic probe for transmitting an ultrasonic wave toward a cavity wall of the patient and receiving an ultrasonic wave reflected by the cavity wall to produce an echo signal. A plurality of organ marks denoting a plurality of organs and a plurality of posture marks representing postures of the patient on a bed are previously stored in a memory. Any desired organ mark and posture mark are selectively read out of the memory and the thus selected organ mark and posture mark are displayed on a display screen of a monitor together with the ultrasonic image as a composite image. In superimposition on the organ mark there is further displayed an ultrasonic wave transmitting point indicating mark. By monitoring the composite image displayed on the monitor screen, it is possible to know a part of the organ whose ultrasonic image is displayed as well as a point and a direction from and in which the ultrasonic wave is transmitted. Therefore, the diagnosis can be performed very easily and accurately.

Dependent claims

An ultrasonic diagnosing apparatus comprising:

an ultrasonic probe which is insertable into a cavity of a patient for transmitting an ultrasonic wave toward a cavity wall and receiving an ultrasonic wave reflected by the cavity wall to generate an echo signal;
an image signal processing circuit connected to said ultrasonic probe for receiving said echo signal and processing the echo signal to produce an ultrasonic image signal;
a memory means for storing a plurality of posture marks which represent postures of the patient on a bed and a plurality of organ marks which represent organs of the patient;
a selecting means for selecting a desired posture mark among said plurality of posture marks and a desired organ mark among said plurality of organ marks to produce a posture mark signal and an organ mark signal;
an image processing means for mixing said posture mark signal representing said desire posture mark and said organ mark signal representing said desired organ mark with the ultrasonic image signal generated by said image signal processing means to produce a composite image signal;
and
a displaying means for receiving said composite image signal to display a composite image of ultrasonic image, posture mark and organ mark.
