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