ABSTRACT:
An ultrasonic display apparatus which utilizes novel electrical and optical means to produce an image which is spatially superimposed within the exact area of the patient's body being scanned is disclosed. The ultrasonic display apparatus includes a cathode ray tube, a planar mirror and a transducer which are mounted within a housing having a viewing window formed therein. The cathode ray tube includes a generally planar viewing face which lies in a first plane. The planar mirror lies in a second plane. One of the mirror and cathode ray tube is pivotally mounted within the housing such that the angle between the first and second planes is adjustable. The transducer is pivotally mounted in the housing and is connected to electric circuit means which cause the transducer to generate a succession of ultrasonic beams which propagate along a third plane. Angle adjustment means are provided for adjusting the angle of the third plane with respect to the housing. The angle adjustment means also maintains the angle between the second and third planes equal to the angle between the first and second planes when the angle of the third plane is changed with respect to the housing.
