Standard calibration of ionization chambers used in radiation therapy dosimetry and evaluation of uncertainties
Background: Absolute dosimetry of external beam radiotherapy is carried out by the use of ionization chambers. These chambers must be calibrated at a standard dosimetry laboratory before any use in clinical dosimetry. The secondary standard dosimetry laboratory of Iran (SSDL) has the duty of calibrating the ionization chambers used in radiotherapy centers in Iran. Materials and Methods...
متن کاملImplications of cancer staging uncertainties in radiation therapy decisions.
INTRODUCTION Radiation therapy (RT) for cancer is a critical medical procedure that occurs in a complex environment involving numerous health professionals, hardware, software, and equipment. Uncertainties and potential incidents can lead to inappropriate administration of radiation to patients, with sometimes catastrophic consequences such as premature death or appreciably impaired quality of ...
متن کاملModeling Internal Radiation Therapy
A new technique is described to model (internal) radiation therapy. It is founded on morphological processing, in particular distance transforms. Its formal basis is presented as well as its implementation via the Fast Exact Euclidean Distance (FEED) transform. Its use for all variations of internal radiation therapy is described. In a benchmark trial, FEED proved to be truly exact as well as f...
متن کاملUncertainties in Bayesian Geometric Models
Deformable geometric models fit very naturally into the context of Bayesian analysis. The prior probability of boundary shapes is taken to proportional to the negative exponential of the deformation energy used to control the boundary. This probabilistic interpretation is demonstrated using a Markov-Chain Monte-Carlo (MCMC) technique, which permits one to generate configurations that populate t...
متن کاملComparison of geometric uncertainties using electronic portal imaging device in focal three-dimensional conformal radiation therapy using different head supports.
AIMS AND OBJECTIVES To study the geometric uncertainties in the treatment and evaluate the adequacy of the margins employed for planning target volume (PTV) generation in the treatment of focal conformal radiotherapy (CRT) for patients with brain tumors treated with different head support systems. MATERIALS AND METHODS The study population included 11 patients with brain tumors who were to be...
