Radiotherapy Planning

PET Clinics, 2015
Incorporation of PET/computed tomography (CT) in radiotherapy planning plays a critical role in assisting gross tumor volume delineation for radiotherapy planning and delivery. As radiotherapy techniques evolve to become more conformal with the increasing use of intensity-modulated radiotherapy and stereotactic body radiotherapy, whereby sharp dose ...

Radiotherapy Planning

2023
Abstract Radiotherapy treatment is still based on the immutable principles of physics and biology and the fundamental approaches of logical thinking, audit, and appropriate analysis of treatment outcomes, including patterns of failure, research, and collaborative working must still underpin practice.

Planning a Radiotherapy Department

Clinical Oncology, 2017
The master planning of new radiotherapy facilities requires the input and engagement of a range of highly specialised professionals, both in the construction and health sector. Although radiation protection and safety aspects of radiotherapy services are universal, low and middle income countries are often presented with unique challenges that also ...

Automated Radiotherapy Treatment Planning

Seminars in Radiation Oncology, 2019
The "treatment planning" component of managing a radiotherapy patient currently consumes hours, even days, of human effort. The time and workforce demands of the current planning paradigm can expose patients to delays and potentially substandard treatments, all while standing as seemingly insurmountable roadblocks to adaptive radiotherapy.

CT for intracavitary radiotherapy planning

American Journal of Roentgenology, 1980
Twenty-two patients with malignant uterine tumors were examined with computed tomography (CT) for treatment planning after insertion of an afterloading Fletcher applicator. The CT findings maximized the individualization of treatment planning, including the number, dosage, and loading arrangement of radioactive sources.

Radiotherapy planning using computed tomography

Cancer, 1981
A critical look at the use of computed tomography (CT) for radiation therapy planning shows problems which all arise from incorrect positioning of the patient. CT is an excellent tool for therapy planning if the patient is positioned identically at the CT scanner and on the therapy couch. This is accomplished by installing matching laser systems at the

Computed tomography for radiotherapy planning

International Journal of Radiation Oncology*Biology*Physics, 1980
Abstract Images obtained by X-ray transmission computed tomography (CT) assist in planning external beam radiation therapy. Quantitatively, contiguous transverse tomograms may be used to compute radiation dose distributions, based on patient-specific geometry and density of the tissues irradiated.
