Conventional Simulation Radiation Therapy

Internal radiation therapy is commonly used to treat prostate cancer and may be used alone or in. Simulation is a process during which the patient is prepared for therapy.

Simulation for conventional.

Conventional simulation radiation therapy. A patient to be simulated is placed on the conventional simulator table in the treatment position. Internal radiation therapy or brachytherapy is delivered by placing sealed radioactive isotopes inside of the body using needles or catheters. While the majority of patients receiving external beam radiation therapy treatment are planned by ct simulation a significant number of them are still planned using conventional simulators for various reasons.

Conventional simulation implies the use of a machine capable of the same mechanical movements as treatment units. The information collection process in a conventional simulation is often fragmented and done with primitive tools. This process is experimental and the keywords may be updated as the learning algorithm improves.

Daniel bourland in clinical radiation oncology third edition 2012. Conventional simulators are a combination of diagnostic x ray machine and certain components of a radiation therapy linear accelerator 1 6. The supine position is most common but prone positioning and other geometries are also used.

The radiation therapy simulator has been an integral component of the treatment planning process for 30 years. Recent developments in imaging and computer power have led to the ability to acquire large three dimensional data sets for target localization and complex treatment planning for radiation therapy. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

A conventional simulator as seen in fig. The patient is placed in the treatment position and the radiation field or fields are marked. Conventional simulation during simulation the defined treatment set up which is prepared on the tps will be simulated on the simulator using the light field projection and the radiographic or fluoroscopic modes provided by the conventional simulator.

Internal radiation therapy may be given in high or low dosage rates and may be temporary or permanent. Radiation therapy or radiotherapy often abbreviated rt rtx or xrt is therapy using ionizing radiation generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. This process will help to mimic the radiation therapy beams in terms of divergence.
