High Dose Rate (HDR) System

     A Nucletron high dose rate (HDR) system is used to treat lesions by passing a tiny Iridium-192 radioactive source into the patient via an implanted catheter.  This radioactive source is under computer control; it can be programmed to dwell for various durations at specified locations within the catheter to produce a desired radiation dose distribution.  With the Nucletron system, many lung lesions and gynecological lesions can be treated on an out-patient basis, which reduces the cost of treatment for the patient.

     The Nucletron system is remotely controlled.  The radioactive source is securely contained and shielded while the patient is being prepared for treatment and at the conclusion of a treatment.  Thus, there is no exposure to medical personnel around the patient.

     In our department, we routinely use this system for the management of lung cancers and gynecologic cancers to optimize clinical results and patient convenience.
