Abstract
Abstract An ultrasonic device for examining the internal parts of the body comprising a plurality of ultrasonic transmitters mounted along a horizontal line on a movable carriage and triggered sequentially. A plurality of receivers is mounted on the carriage along a vertical line that intersects the horizontal line at right angles. The movement of the carriage is synchronized with the deflection of an electron beam in a PPI cathode-ray tube to provide a visual display of the surface contour of the internal body part under investigation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A device for examining internal body parts by means of ultrasonic waves comprising, ultrasonic transmitter means mounted for movement along the surface of the body, said ultrasonic transmitter means comprising a plurality of separate transmitters of ultrasonic oscillations arranged in a flat plane along a straight or curved line, control means for triggering said separate transmitters in sequence to produce sequentially ultrasonic waves of short duration in narrow beams directed to the body part to be examined, and a plurality of receivers arranged in a plane at right angles to the plane of the sound transmitters along a line which intersects the line of the sound transmitter, said receivers being mounted for movement with said transmitters along the surface of the body so as to intercept the ultrasonic waves propagating through the body after being reflected from the surface of the body part under examination.
Claim 2
Independent Claim
145 words
A device for examining internal body parts by means of ultrasonic waves comprising, ultrasonic transmitter means mounted for movement along the surface of the body, said ultrasonic transmitter means comprising a plurality of separate transmitters of ultrasonic oscillations arranged in a flat plane along a straight or curved line, control means for triggering said separate transmitters in sequence to produce sequentially ultrasonic waves of short duration in narrow beams directed to the body part to be examined, and a plurality of receivers arranged in a plane at right angles to the plane of the sound transmitters along a line which intersects the line of the sound transmitter, said receivers being mounted for movement with said transmitters along the surface of the body so as to intercept the ultrasonic waves propagating through the body after being reflected from the surface of the body part under examination.
Claim 3
Dependent Claim
54 words
A device as claimed in claim 1 further comprising, a carriage member mounted for movement along a given guide path, a cross-shaped support member mounted on said carriage, and first and second support arms fastened on said cross-shaped support members, said transmitters and receivers being mounted on said first and second support arms, respectively.
Claim 4
Dependent Claim
32 words
A device as claimed in claim 2, characterized in that the guide path has a curved shape matching the curvature of the surface of the body having the organ to be examined.
Claim 5
Dependent Claim
48 words
A device as claimed in claim 2 further comprising a control member including means for displacing the carriage with the transmitters and receivers along said guide path, and said control means includes a control-system for repeating the sequential triggering of the transmitters during the displacement of the carriage.
Claim 6
Dependent Claim
19 words
A device as claimed in claim 1, characterized in that the repetition frequency of said control means is variable.
Claim 7
Dependent Claim
32 words
A device as claimed in claim 1 wherein said control means comprises, an electronic pulse generator, and a pulse distributor selectively interconnecting the output of said pulse generator with said separate transmitters.
Claim 8
Dependent Claim
88 words
A device as claimed in claim 6 further comprising, means for moving said transmitters and receivers, a cathode ray tube with means for radially deflecting the electron beam across the display screen, a control member having its input coupled to the output of the pulse generator and a first output for controlling said moving means and thereby the movement of said transmitters and receivers and a second output for controlling the sweep of the cathode ray tube beam in synchronism with the movement of said transmitter and receivers.
Claim 9
Dependent Claim
82 words
A device as claimed in claim 6 further comprising computer means coupled to the outputs of the pulse distributor and the outputs of said receivers and including means for determining the distance between a point on the surface of the internal body part that reflects the ultrasonic energy from a transmitter and the intersection point of said line of transmitters and said line of receivers by analyzing the transit time of the ultrasonic energy from a given transmitter to a given receiver.
