Patient Specific Radiation Dose Tracking: Improving Quality Assurance in Radiology Practices

A Specific Patient Quality Assurance (PSQA) procedure for a Co-60 source based High Dose Rate Brachytherapy

Introduction: In radiation therapy, accurate dose determination and precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. The current study aims the development and clinical application of the Patient Specific Quality Assurance (PSQA) procedures for nasopharyngea...

ROC analysis in patient specific quality assurance.

PURPOSE This work investigates the use of receiver operating characteristic (ROC) methods in patient specific IMRT quality assurance (QA) in order to determine unbiased methods to set threshold criteria for γ-distance to agreement measurements. METHODS A group of 17 prostate plans was delivered as planned while a second group of 17 prostate plans was modified with the introduction of random m...

Patient-Specific Radiation Dose and Cancer Risk in Computed Tomography Examinations in Ondo, Nigeria

Introduction: The dose in computed tomography (CT) often approach or exceed the optimum levels, thereby increasing the probability of cancer induction. With wide application of this diagnostic test, it is expedient to determine the effective dose (ED) for each patient to estimate their cancer risk. This study was conducted to investigate the patient-specific dose (PSD) and cancer risk in CT exa...

A quality assurance program in dental radiology.

A quality assurance program in radiology provides the basis for systematic measurement of various parameters which affect the quality and production of a radiographic image. We have outlined a program which can be implemented in dental offices by dentists or auxiliary personnel without sophisticated instruments. Tests designed to establish the adequacy of specific functions are described togeth...
