ABSTRACT:
A SPECT system includes two or more radiation detector heads (32) and (34) which are mounted opposite each other to a gantry (30) for rotation about a subject. Each detector head has a collimator (38) mounted in front of the detector head. The collimator (38) is separated into a top portion (40) and a bottom portion (42). The top portion (40) and bottom portion (42) are spaced from each other to provide a gap (44) within the collimator (38). The gap (44) receives one or more devices to provide additional functionality during a scan. The insertable devices include a transmission radiation source (52), a calibration source, a radiation filter, and others.
