Location head for an apparatus for detecting very small breast anomalies

Abstract

A computer controlled apparatus for detecting breast tumors by mechanically palpating a breast in a full scan manner to detect small lumps or anomalies. The patient is positioned on a fully adjustable bed and oriented relative to the apparatus. A detection head mounted for movement in three dimensions is positioned above the bed. A palpation finger is brought into pressure contact with a sequence of small areas across the entire breast, palpating each area to measure tissue density. Concurrent with the palpation scan, a scan of breast color and temperature is conducted. A locator head positions the detector for the scan in a manner that assures repeatability during each of a series of periodic examinations. This system detects very small lumps and allows easy, accurate monitoring of suspicious areas over an extended time period. Several different embodiments of the detection head and location head are described.
