  • Ultrasonic diagnostic system
    Patent number: 5383461
    Abstract: An extended frame memory is provided in parallel with a frame memory, and tomographic images having a number required for computing the cubage of a part to be ultrasonically scanned are stored in the extended frame memory. Thereafter, the thus stored tomographic images are successively read out, and sectional areas are computed from the stored tomographic images. Then, the cubage of the part to be ultrasonically scanned of an examinee is calculated from the thus computed sectional areas. The computation of the cubage is conducted after the tomographic images having a number required for the computation of the cubage are stored in the extended frame memory, thereby it is possible to reduce the burden to the examinee.
