Other radiation therapy machines which incorporate real-time MRI tracking of tumors are currently in development. MRI-guided radiation therapy enables clinicians to see a patient's internal anatomy in real-time using continual soft-tissue imaging and allows them to keep the radiation beams on target when the tumour moves during treatment.

The advent of new imaging technologies, including magnetic resonance imaging (MRI) in the 1970s and positron emission tomography (PET) in the 1980s, has moved radiation therapy from 3-D conformal to intensity-modulated radiation therapy (IMRT) and to image-guided radiation therapy tomotherapy. These advances allowed radiation oncologists to ...
In a medical facility, such as a hospital or clinic, a gantry holds radiation detectors and/or a radiation source used to diagnose or treat a patient's illness. Radiation sources may produce gamma radiation, x-rays, electromagnetic radiation, or magnetic fields depending on the purpose of the device. [1] [2]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
Radiation exposure from medical imaging in 2006 made up about 50% of total ... A magnetic resonance imaging ... (MRI), ultrasound, and radiation therapy. ...
[2] [3] [4] In other words, theranostics combines radionuclide imaging and radiation therapy which targets specific biological pathways. Technologies used for theranostic imaging include radiotracers, contrast agents, positron emission tomography, and magnetic resonance imaging. [3] [5] It has been used to treat thyroid cancer and ...
A Therac-25 had been in operation for six months in Marietta, Georgia at the Kennestone Regional Oncology Center when, on June 3, 1985, applied radiation therapy treatment following a lumpectomy was being performed on 61-year-old woman Katie Yarbrough. She was set to receive a 10-MeV dose of electron therapy to her clavicle. When therapy began ...
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
