Computed tomography guided radiotherapy

What is CBCT radiation therapy?
Medical imaging is an indispensable tool in radiotherapy for dose planning, image guidance and treatment monitoring.
Cone beam CT (CBCT) is a low dose imaging technique with high spatial resolution capability as a direct by-product of using flat-panel detectors..
What is CT guided radiation therapy?
Image-guided radiation therapy, or IGRT, is a type of cancer treatment that uses imaging technologies such as PET, MRI, and CT to more accurately and safely deliver radiation to cancer cells..
What is CT simulation for radiation?
Simulation is a process carried out by the radiation therapist under the supervision of the radiation oncologist.
It is a mock-up procedure of a patient treatment.
Inside the simulation room is a CT scanner specifically designed for the radiation therapy department..
What is the advantage of MR image guided radiotherapy?
There are several advantages to IGRT therapy: More precise radiation doses can safely be delivered to tumors with fewer side effects.
Reduced treatment toxicity..
What is the role of CT in radiotherapy?
CT scans are regularly used to plan radiotherapy, so they play an important role in cancer treatment.
Doctors use CT scans to decide how much tissue will be exposed to radiation in order to treat tumors..
What is tomography radiation therapy?
TomoTherapy\xae is both a radiation delivery system and a CT scanner that provides .
1. D images before each treatment.
A CBCT system impresses with its simple operability and integration into routine practices, shorter examination times—including higher image sharpness and lower radiation dose—increased X-ray tube efficiency and lower image distortion because of movements of the patient.
CT imaging involves the use of x-rays, which are a form of ionizing radiation.
Exposure to ionizing radiation is known to increase the risk of cancer.
Standard x-ray procedures, such as routine chest x-rays and mammography, use relatively low levels of ionizing radiation.
Planning usually takes place in a CT scanner.
This provides an exact mock-up of the treatment position.
The radiographers will explain what will happen during planning and carry out any preparation you may need.
This scan will give your doctor and radiographers a detailed picture of the area that needs treatment.
Simulation is a process carried out by the radiation therapist under the supervision of the radiation oncologist.
It is a mock-up procedure of a patient treatment.
Inside the simulation room is a CT scanner specifically designed for the radiation therapy department.
The application of other imaging modalities, such as magnetic resonance (MR) imaging and positron emission tomography (PET), can provide additional information in order to more precisely define tumor localization for treatment planning using radiation therapy [6–8].
