Abstract
A mammalary biopsy needle positioning scheme that improves on the system of U.S. Pat. No. 4,821,727. In the present invention, the arrival of the needle holder into a pixel is distinguished by comparing latest data per pixel to average data per pixel. If the comparison reveals marked differences from the average value, then the average value is discarded and the new data is used whereas in the absence of marked differences, the new data is averaged with the old average. The result is images with highlighted needle holder insertion information thereby providing images of the needle holder in the breast in a much shorter time than provided by the prior art and/or with smaller X-ray doses.
