A radiation therapy machine enabling aligning of a patient for radiation treatment based on an earlier tomographic scan of the patient uses projection images used to reconstruct a tomographic image rather than reconstructed images. The machine compares the projection images directly to projection images ...
Stereotactic body radiation therapy (SBRT), or stereotactic ablative radiotherapy, is a type of radiation therapy that precisely targets a tumor with high doses of radiation by using several beams of various intensities aimed at different angles.
"I could not have treated this on any other treatment machine than an MR-Linac." - Prof. Dr. Cihan Gani Images courtesy of University of Tubingen, Germany Clinical evidence Learn more about how MR-guided radiation therapy is benefiting patients with oligometastatic disease. Clinical trials Webinar...
Clinician will choose the type of radiotherapy and the machine for treatment according to the type of cancer and where it is in the body. There are different types of external beam radiation therapy treatment. They include: 3D Conformal radiotherapy (3DCRT) 3DCRT is now a very common in radi...
Intensity-Modulated Radiation Therapy The radiation therapy component of theCMTis the source of much morbidity. Traditionally, the delivery of radiation treatments is based on CT-guided or three-dimensional images of the pelvis (conformal radiation therapy). Intensity-modulated radiation therapy (IMRT) ...
The purpose of this research is to improve the physician's ability to localize and delineate the extent of the tumor by incorporation of the PET images into radiation therapy treatment planning. A machine-based CT-PET fiducial fusion method was implemented for head and neck carcinoma radiation ...
A human interface to be used with irradiation machine in a computed tomography machine wherein x-ray computed tomography images are individually display on a computer screen and an operator uses a manual cursor control device to trace various irradiation zones on the image, identify desired dose wi...
On-treatment verification images were taken mainly using X-ray film in a holder, she adds. The more “cutting edge” machines had an imaging device that was hooked onto the machine when an operator wanted to use it. Treatment planning was carried out using a simulator, which was essentially...
