What is an HDR Afterloader?

HDR (high dose rate) brachytherapy is conducted with a so-called HDR afterloader, also known as a remote afterloading system. With the help of applicators and catheters, the very small radiation source is driven from a shielded safe – located inside the afterloader – directly into or next to the tumor.

What is brachytherapy system?

Brachytherapy is a type of radiation therapy where a sealed radiation source is placed next to or inside the area being treated. It is also important to women’s health because it is a common treatment for cervical, breast, and skin cancer.

What is a Flexitron?

Summary. The Elekta Flexitron Remote Afterloader is used to insert a radioactive source directly into a tumor, where it stays for a short time. This form of treatment delivers a precise, localized dose of radiation while minimizing exposure to healthy tissue.

What is an Afterloader?

Introduction to High Dose Rate Brachytherapy (HDR) The source is housed in a device called an afterloader. The computer-guided afterloader directs the source into the treatment catheters placed in and around the prostate by the brachytherapy physician.

How does HDR brachytherapy work?

HDR brachytherapy is a form of internal radiotherapy where an oncologist: Temporarily implants a catheter — a small plastic tube or balloon — in the tumor area. Places highly radioactive material inside the body for a short time and then retracts it using a remote control.

What is Afterloader brachytherapy?

Remote afterloading brachytherapy systems automatically administer a radioisotope directly to cancerous tissue, thereby minimizing the radiation dose to surrounding tissue and eliminating the radiation exposure to hospital staff.

Is HDR brachytherapy painful?

You shouldn’t feel any pain during brachytherapy, but if you feel uncomfortable or have any concerns, be sure to tell your caregivers. Once the radioactive material is removed from your body, you won’t give off radiation or be radioactive.
