Magnetic Resonance Imaging (MRI) is not a type of radiation therapy imaging technique. It is a medical imaging technique that uses a strong magnetic field and radio waves to create detailed images of the inside of the body.

Radiation therapy imaging is used for a variety of purposes, including diagnosing diseases, planning and guiding radiation therapy treatments, and monitoring the response of tumors to radiation therapy.

Ultrasound imaging is not a type of radiation therapy imaging modality. It is a medical imaging technique that uses sound waves to create images of the inside of the body.

Computed Tomography (CT) is the most common type of radiation therapy imaging technique. It uses X-rays and a computer to create detailed images of the inside of the body.

Radiation therapy imaging plays a vital role in the treatment of cancer. It is used to diagnose cancer, plan and guide radiation therapy treatments, and monitor the response of tumors to radiation therapy.

Ultrasound imaging is not a type of radiation therapy imaging technology. It is a medical imaging technique that uses sound waves to create images of the inside of the body.

Cone-beam computed tomography (CBCT) is primarily used in radiation therapy to verify the accuracy of radiation therapy treatments. It is used to ensure that the radiation beam is properly aligned with the target area and that the dose of radiation is delivered as planned.

Computed Tomography (CT) is not a type of radiation therapy imaging modality used for functional imaging. It is a type of anatomical imaging modality that provides detailed images of the structure of the body.

Fluoroscopy is used in radiation therapy to verify the accuracy of radiation therapy treatments. It allows the radiation therapist to visualize the target area and the surrounding structures in real time, ensuring that the radiation beam is properly aligned and that the dose of radiation is delivered as planned.

Ultrasound imaging is not a type of radiation therapy imaging technology used for image-guided radiation therapy (IGRT). It is a medical imaging technique that uses sound waves to create images of the inside of the body.

Image-guided radiation therapy (IGRT) is used to verify the accuracy of radiation therapy treatments. It allows the radiation therapist to visualize the target area and the surrounding structures in real time, ensuring that the radiation beam is properly aligned and that the dose of radiation is delivered as planned.

Ultrasound imaging is not a type of radiation therapy imaging modality used for adaptive radiation therapy (ART). It is a medical imaging technique that uses sound waves to create images of the inside of the body.

Adaptive radiation therapy (ART) is used to modify the radiation therapy plan based on changes in the tumor and surrounding structures. This allows the radiation therapist to deliver a more precise and effective dose of radiation to the target area while minimizing damage to healthy tissues.

Ultrasound imaging is not a type of radiation therapy imaging modality used for stereotactic body radiation therapy (SBRT). It is a medical imaging technique that uses sound waves to create images of the inside of the body.

Stereotactic body radiation therapy (SBRT) is used to deliver a high dose of radiation to a small target area with minimal damage to surrounding tissues. This is achieved by using precise imaging techniques to accurately target the tumor and by delivering the radiation in a highly focused manner.
