Abstract
The invention relates to a biopsy arc intended to be the support of examination needles in connection with computer tomography. The arc is removably secured to the patient's table and angularly adjustable to be adapted to the direction of the respective section image plane. The arc has a plurality of apertures directed towards the area enclosed by the arc for guiding the examination needles. The arc is made of a material which has an attenuation with respect to X-ray radiation which lies at or below the value exhibited by organic tissue, whereby the arc as well as organs can be brought to appear and stand out together on the section picture in order that a suitable aperture and direction of examination can be selected without risk of disturbing artefacts.
