PCT No. PCT/DK84/00011 Sec. 371 Date Sep. 21, 1984 Sec. 102(e) Date Sep. 21, 1984 PCT Filed Feb. 7, 1984 PCT Pub. No. WO84/03034 PCT Pub. Date Aug. 16, 1984.A stand-off cell for an ultrasonic scanner head has a slit in which a biopsy needle can be guided. The whole introduction will therefore take place in the area supervisable by the scanner head so that the needle can be guided in a secure manner when making a biopsy. The stand-off cell can be made of a plastics with the same acoustic impedance as tissue and can therefore be manufactured very cheaply. After the needle is introduced the stand-off cell can be removed as the needle slides out through the slit. This makes the biopsy easier and makes it possible to utilize the scanner head in the best way.
