An apparatus for the examination of living tissues, comprises means (228) for illuminating the tissue with infra-red-containing electromagnetic radiation, a television camera (202) for receiving the radiation which is transmitted through the tissue and means (216) for producing an image of the received radiation. In addition a probe (224) is provided for applying ultrasound to a region of the tissue and for receiving the reflected ultrasonic signals from the region. The signals obtained are representative of the velocity of blood flow in the region and means (216) are provided for generating from the signal an image which provides an indication of blood flow velocity in the region. The apparatus further comprises an arm rotatably mounted on a support about a pivot, the television camera (202) being mounted on the arm on one side of the pivot. A device for holding the tissue to be imaged by the television camera is mounted on the arm on the other side of the pivot. |
