Radiation Therapy Room Types

Brachytherapy

Brachytherapy (also referred to as internal radiotherapy, sealed source radiotherapy, curietherapy or endocurietherapy) – a radiation source is implanted in the body, near or directly inside the tumor. Common radiation sources utilized in brachytherapy include Cesium-137, Iridium-192, Cobalt-60, Iodine-125, Palladium-103, and Ruthenium-106. There are several Brachytherapy treatment options available:

• Low-Dose Rate (LDR) - low emission radiation at a rate of up to 2 Gy/hr-1
  
  
• Medium-Dose Rate (MDR) - the doses of radiation delivered fall in a mid-range of 2 Gy/hr-1 to 12 Gy/hr-1
  
  
• High-Dose Rate (HDR) - dose rates exceed 12 Gy/hr-1 d.
  
  
• Pulsed-Dose Rate (PDR)- short pulses of radiation are emitted, typically once an hour, to simulate the overall rate and effectiveness of LDR treatment.
