Intraoperative radiation therapy (IORT) is radiation therapy that is administered during surgery directly in the operating room (hence intraoperative ). Usually therapeutic levels of radiation are delivered to the tumor bed while the area is exposed during surgery. IORT is typically a component in the multidisciplinary treatment of locally ...
The most common type of particle therapy as of August 2021 is proton therapy. [1] In contrast to X-rays ( photon beams) used in older radiotherapy, particle beams exhibit a Bragg peak in energy loss through the body, delivering their maximum radiation dose at or near the tumor and minimizing damage to surrounding normal tissues.
Radionuclide therapy ( RNT, also known as unsealed source radiotherapy or molecular radiotherapy) uses radioactive substances called radiopharmaceuticals to treat medical conditions, particularly cancer. These are introduced into the body by various means ( injection or ingestion are the two most commonplace) and localise to specific locations ...
It has also been used with Stereotactic Body Radiation Therapy to assist with the initial set-up and detect intrafraction patient motion throughout treatment. For stereotactic surgery , SGRT allows a frameless system to be used to monitor the surface of the patient within an open-face immobilization mask.
Radiation Therapy Oncology Group. "The Radiation Therapy Oncology Group (RTOG) was initially organized in 1968 under the direction of Simon Kramer as a national cooperative group for the purpose of conducting radiation therapy research and clinical investigations in order to treat cancers, including endometrial and cervical cancer.

Bolus (radiation therapy) In radiation therapy, bolus is a material which has properties equivalent to tissue when irradiated. It is widely used in practice to reduce or alter dosing for targeted radiation therapy.
Brachytherapy is a form of radiation therapy where a sealed radiation source is placed inside or next to the area requiring treatment. Brachy is Greek for short. Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, esophageal and skin cancer and can also be used to treat tumours in many other body sites. [1]
