DEVICE FOR LIMITING DECODING ARTEFACT APPEARANCE FOR AN ENCODED MASK GAMMA CAMERA

摘要

The invention relates to a device limiting the appearance of decoding artefacts for an encoded mask gamma camera comprising a gamma radiation sensor (3) arranged in front of the encoded mask (1) and provided with a view field having an area (20) which is partially encoded by said encoded mask (1). The inventive device also comprises a recessed part (30) which is impervious to gamma radiation, is arranged oppositely to the sensor (3) with respect to the encoded mask (1) and obscure the partially encoded area of the view field for the sensor (3).
