CT guidance for insertion of radiation therapy fields involves using a CT scan to accurately map the area of your body where radiation will be applied. This ensures the radiation targets only the necessary area, minimizing impact to healthy tissues.

Intensity-modulated radiation therapy (IMRT) is a type of cancer treatment. It uses advanced technology to manipulate photon beams of radiation to conform to the shape of a tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional shape of the tumor by modulating—or controlling—the intensity of the radiation beam. This can result in better tumor control and less harm to healthy tissue.

The design and construction of a complex radiation treatment device is a process where a specialized instrument is created. This device targets harmful cells with high-energy rays to destroy or damage them, while minimizing impact on healthy cells. This aids in treating conditions like cancer.

This procedure involves using high-energy radiation to target and treat disease. It covers 3 or more distinct areas, using custom blocks to protect healthy tissue. Tangential ports, wedges, and rotational beams help direct the radiation. An electron beam of 11-19 million electron volts (mev) is used for deep-seated conditions.

Radiation therapy dose calculation is a process to determine the exact amount of radiation needed to treat a specific area in the body. This calculation helps ensure the treatment is effective while minimizing harm to healthy tissues. It's a key part of planning your radiation therapy.

In radiation therapy, intra-fraction localization and tracking monitor patient or target movement during treatment. This ensures that radiation is accurately delivered to the correct area. Techniques like 3D positional tracking, gating, and 3D surface tracking are used to enhance precision.
