Abstract (en)

For the purpose of producing a real time image of a given sector of a plane in a subject, a curved faced, disc shaped transducer (100) and an oppositely facing, circular angularly disposed mirror (106) form the transmission and reception path of a mechanical sector scan imaging system. The transducer (100) and a mirror (106) are mounted on a common axis (121), and a shaft (113) upon which the mirror (106) is affixed oscillates about that axis (121). Energy is deflected from the mirror (106) into the patient, the echoes are reflected back at the mirror (106) and in turn along the axis (12) towards the transducer (100). Through a belt drive mechanism, a motor provides the oscillating motion, in turn scanning the ultrasound beams through the subject by virtue of the mirror motion. An optical encoder records positional information from the motor, for coordination of the mirror oscillation with transducer signals, and thereby for the assembly of a composite image.
