[A preliminary report of computerized ultrasonography in obstetrics and gynecology: a new technique of C-mode (author's transl)].

UNLABELLED: In order to obtain a three-dimensional ultrasonogram as a first step for a general visualizing diagnosis, a new computerized ultrasonography was tried with patients from our obstetric and gynecological department, with the following results: 1. Time required: Collection of data for the three-dimensional part measuring 17 X 17 X 8.5cm took 17 seconds (Scanning time), and formation of the 32-image longitudinal sections and coronal sections (C-mode) took 46 seconds and 1 minute 54 seconds, respectively. Formation of the 64-image longitudinal sections and coronal sections (C-mode) took 1 minute 20 seconds and 3 minutes 20 seconds, respectively. 2. Images: The recorded and reproduced images were identical to the originals macroscopically and even as indicated on the line printer. The coronal images (C-mode) and the longitudinal images could well stand practical use. 3. Reproduction of images: All data were stored on magnetic tape which could be processed as needed. 4. CLINICAL RESULTS: (a) In obstetric patients, the images enabled us to confirm the location and expansion of the placenta and fetus more clearly. (b) In gynecological patients, it proved to be easy to get a whole view permitting better comprehension of the tumor shape, its internal components and its relation with the surrounding organs in a three-dimensional way.
