By transrectal ultrasonography the volume of the prostate is determined two times using the conventional planimetric method. Thereafter the US scanner is placed in a fixture which is retracted repeatedly. For this a motordrive has been developed. The images of each section are improved by digital processing, and the prostatic outline is determined interactively by developed image processing software. In this manner the total volume of the prostate is calculated. In a post-mortem study prostates of 9 cadavers were measured with the conventional planimetry and by means of digital processing and analysis. The results were compared with the results obtained after removal of the prostate. In a clinical study the prostatic volumes of 20 patients were measured in a similar way. The results of the two methods are compared. Both in the cadaver study and the patient study we found a good correlation between the conventional method and the computerized method. In the cadaver study we noticed a better correlation between the prostatic volume found with the computerized method and the volume obtained after prostatectomy. Also the reproducibility of this method turned out to be better.
