title: Laser backpointer for use with a radiotherapy simulator.
abstract: A radiotherapy simulator with image intensification has been equipped with a laser backpointer which does not need to be removed during fluoroscopic examinations, provides negligible interference with the fluoroscopic image, and results in significant reductions in the time required for mark-up of patients. Accuracy of set-ups may be improved since rechecking of patient positioning has been simplified.
