[A trial of digitization and digital analysis from analogue clinical images of the renal cancer].
The advancement in image diagnostic methods has been great in recent years and image diagnosis has become indispensable for the diagnosis of renal and other cancers. However, the clinical images are fixed and recorded on film as analog images for storage and the expansion of storage space, the poor efficiency in arrangement and control and the inconvenience of transfer have become big problems. Digitization of the clinical images offers the advantages of solving these problems and of allowing a variety of image analyses to be made easily. The tendency is for the digitization of all images for medical use in the near future. We applied a handy image analysis system (Shonic GA) using a personal computer as the mainframe and tried to digitize the analog images of a pyelogram, DSA, ultrasonogram, and X-ray CT of renal carcinoma for digital analysis. The results were displayed. This system is handy and easy to operate and thus is useful for the purposes of understanding and gaining experience in digitization and digital analyses of images for medical use.
