A multileaf delineator system for a radiotherapy simulator

• Multileaf collimators are offered as an accessory to many accelerators for conformal radiotherapy and the dose planning systems are capable of calculating multileaf collimated beams. There is further a frequent desire to verify the radiation fields on a radiotherapy simulator prior to the actual treatment. For this purpose,an accessory to the simulator was developed (the multileaf delineator). With this unit the front end of the individual leaves are indicated both on the skin of the patient and in the x-ray image. All anatomical structures both outside and inside the field edge are, however, still fully visible.
