This invention concerns an improved electronic sector scanning apparatus and method, used primarily for scanning human tissue to determine its internal structure. A typical ultrasonic scanning unit was a transducer unit for sending and receiving ultrasonic energy. In a transmit mode of operation, the transducer sends incident ultrasonic energy into the patients body. Variations in tissue density within the patient cause a portion of the ulstrasonic energy to be reflected back to the transducer, where the reflected ultrasonic energy is converted into electrical signals. By the.use of interpretative imaging circuitry and display apparatus, these electrical signals can be used to display to a diagnostician internal structure within the human body.
The use of multiple segment ultrasonic transducer units with accomp...
