Auto-segmentation of organs at risk for head and neck radiotherapy planning: from atlas-based to deep learning methods.

Medical Physics (Lancaster), 2020
Radiotherapy (RT) is one of the basic treatment modalities for cancer of the head and neck (H&N), which requires a precise spatial description of the target volumes and organs at risk (OARs) to deliver a highly conformal radiation dose to the tumor cells

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 ...

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.

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 ...

Integration of 68Ga-PSMA-PET/CT in Radiotherapy Planning for Prostate Cancer Patients.

Clinical Nuclear Medicine, 2019
To assess the role of Gallium-labeled-prostate-specific membrane antigen PET/CT (Ga-PSMA-PET/CT) in risk group definition and radiotherapy planning in the initially planned definitive radiotherapy (RT) for prostate cancer patients. METHODS The clinical

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.

Computers in Radiotherapy Planning [PDF]

open access: possible, 1979
When the history of computers in medicine comes to be written, it may well be shown that radiotherapy was the very first application of clinical significance, when the first work was done over 20 years ago by Tsien (1955) in the U.S.A. and by Wood (1962) in the U.K.

Optimisation of radiotherapy treatment planning

Computer Programs in Biomedicine, 1972
Abstract The necessity of studying the whole of a process of optimisation is emphasised. The problem and objective of radiotherapy are stated and the reasons for treatment planning optimisation being at present confined to the distribution of absorbed dose are discussed.
