Abstract
Abstract A transducer located in a reservoir that contains ultrasound-transmitting liquid directs and receives beams of ultrasound onto and from a rotating reflector which is also located in the reservoir. A diaphragm transmits the ultrasound from the liquid to a body which is to be analyzed. The results of the ultrasonic analysis are displayed on a cathode ray tube which is synchronized with the transducer and the rotating reflector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
Apparatus for the ultrasonic analysis of a body comprising a container provided with a membrane to be applied against the body to be analyzed, said container being filled with an ultra-sound transmitting liquid; means for producing a beam of ultrasound energy located in said container; reflector means for reflecting said beam of ultrasound energy into the body through said membrane, said reflector means having a multifaceted, prismatic shape, said reflector means being disposed in said container; driving means for driving said prismatic reflector in a continuous rotation around its symmetry axis; means for displaying two orthogonal axes which correspond to distances and angles to be displayed; means for receiving ultrasound energy reflected from said body, and for providing an output signal representative thereof; and electronic circuit means for synchronizing said reflector means and said display.
Claim 2
Dependent Claim
135 words

Claim 3
Dependent Claim
29 words
The apparatus of claim 1 wherein the means for synchronizing comprises mode selector means for changing a mode in which the graphic display is displayed on the display means.
Claim 4
Dependent Claim
95 words
The apparatus of claim 2, wherein the display means comprises a cathode ray tube and the mode selector means changes the graphic display on the cathode ray tube between an A-mode in which the second display axis of the graphic display corresponds to an intensity of an ultrasonic echo and in which electron beam intensity is constant, and a B-mode in which the second display axis of the graphic display corresponds to a degree of rotation of the reflector means and in which electron beam intensity is varied with said intensity of an ultrasonic echo.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1, wherein the means for synchronizing further comprises means for compensating the graphic display for distortion arising from rotation of the reflector means.
Claim 6
Dependent Claim
31 words
The apparatus of claim 1, wherein the ultrasonic transducer is connected to a transmitter and a receiver and the transmitter and receiver are synchronized with the rotation of the reflector means.
Claim 7
Dependent Claim
15 words
The apparatus according to claim 1 wherein said display means comprises a cathode ray tube.
Claim 8
Dependent Claim
22 words
Apparatus as claimed in claim 1 in which the driving means drives the reflector means in continuous rotation at a constant speed.
Claim 9
Dependent Claim
36 words
Apparatus as claimed in claim 7 in which the electronic control circuit comprises a transmitter and a receiver coupled to an ultrasonic transducer, both transmitter and receiver being synchronized with the rotation of the reflector means.
Claim 10
Dependent Claim
14 words
Apparatus according to claim 1 wherein said driving means is disposed in said container.
Claim 11
Dependent Claim
135 words
Apparatus for ultrasonic analysis of a body comprising: transducer means for producing and receiving a beam of ultrasound energy; means for scanning said body along a single direction with said beam of ultrasound energy, said scanning means including reflector means having a plurality of reflecting surfaces for reflecting said ultrasound energy beam along said single direction, said reflector means rotating about an axis of symmetry parallel to said surfaces of said reflector; means for receiving ultrasound energy reflected from said body; display means having first and second perpendicular display axis for displaying a graphic display corresponding to said reflected energy; and means for synchronizing said reflector means and said display means so that said first display axis of said graphic display corresponds to a distance between a flaw in said body and said reflector means.
Claim 12
Dependent Claim
135 words
Apparatus for ultrasonic analysis of a body comprising: transducer means for producing and receiving a beam of ultrasound energy; means for scanning said body along a single direction with said beam of ultrasound energy, said scanning means including reflector means having a plurality of reflecting surfaces for reflecting said ultrasound energy beam along said single direction, said reflector means rotating about an axis of symmetry parallel to said surfaces of said reflector; means for receiving ultrasound energy reflected from said body; display means having first and second perpendicular display axis for displaying a graphic display corresponding to said reflected energy; and means for synchronizing said reflector means and said display means so that said first display axis of said graphic display corresponds to a distance between a flaw in said body and said reflector means.
