Abstract
An ultrasound sector scan imaging system employing a hand held scan unit is provided with an adapter mounting which is affixed over the scan section, and a sterile glove or boot which encloses the scanner and the mount. A disposable needle guide mechanism is fitted, saddle style, to the mounting over the boot. The disposable guide has a channel for locating the biopsy needle in the sector scan plane, and a depression therein for hand-maintenance of the needle in the guide, during the needle location process, and for free removal of the scanner once the desired position is achieved.
