This document presents recommendations of the American Association Physicists in Medicine (AAPM) for quality assurance computed-tomography- (CT) simulators and CT-simulation process. report was prepared by Task Group No. 66 AAPM Radiation Therapy Committee. It approved Committee Science Council.
Recent years have seen various reviews on the lack of access to radiotherapy often based geographic regions world such as Africa, Asia Pacific, Europe, Latin America and North America. Countries are defined by their national income per capita levels World Bank definitions high income, upper middle lower low income. Within regions, there significant variations in gross (GNI) among different countries, even within similar levels, large exist. This report presents actual status analyses current...
Radiotherapy technology continues to advance and the expectation of improved outcomes requires greater accuracy in various radiotherapy steps. Different factors affect overall dose delivery. Institutional comprehensive quality assurance (QA) programs should ensure that uncertainties are maintained at acceptable levels. The International Atomic Energy Agency has recently developed a report summarizing achievable suggested action levels, for each step process. Overview report: seeks promote...
Two new Fricke dosimeter gel systems with low diffusion rates have been developed for 3D radiation dosimetry purposes. Both consist of a solution 20% (by weight) polyvinyl alcohol (PVA) in 50 mM H2 SO4solution 0.4 ferrous ammonium sulphate and xylenol orange (FX). The difference the two gels is way that gelation process was initiated: either by bringing temperature to (a) +5 °C or (b) -20 before returning them room temperature. These are termed `hydrogel' `cryogel', respectively. hydrogel...
With increasing recognition of growing cancer incidence globally, efficient means expanding radiotherapy capacity is imperative, and understanding the factors impacting human financial needs valuable.A time-driven activity-based costing analysis was performed, using a base case 2-machine departments, with defined cost inputs operating parameters. Four income groups were analysed, ranging from low to high income. Scenario analyses included department size, hours, fractionation, treatment...
The January 2010 articles in New York Times generated intense focus on patient safety radiation treatment, with physics staffing identified frequently as a critical factor for consistent quality assurance. purpose of this work is to review our experience medical staffing, and propose transparent flexible algorithm general use. Guided by documented times required per routine procedure, we have developed robust estimate needs according center-specific workload physicists associated support...
Purpose: To investigate the dosimetric accuracy of sliding window gated IMRT compared with static treatment, using varying dose rates.Materials and methods: This study measured changes in output diode array response changing rate, verified precision motion table, distribution film diodes at two depths rate.During 4DCT (4 Dimensional Computed Tomography), patient's respiratory signals target were recorded imported to XY4D simulation table SUN NUCLEAR Corporation simulate respiration tumour...
Background and purpose. One of the newer audit modalities operated by International Atomic Energy Agency (IAEA) involves audits treatment planning systems (TPS) in radiotherapy. The main focus is dosimetry verification delivery a radiation plan for three-dimensional (3D) conformal radiotherapy using high energy photon beams. has been carried out eight European countries – Estonia, Hungary, Latvia, Lithuania, Serbia, Slovakia, Poland Portugal. corresponding results are presented. Material...
Background: The IAEA has developed and tested an on-site, end-to-end IMRT/VMAT dosimetry audit methodology for head neck cases using anthropomorphic phantom. is described, the results of international pilot testing are presented.Material methods: utilizes a specially designed, commercially available phantom capable accommodating small volume ion chamber (IC) in four locations (three planning target volumes (PTVs) one organ at risk (OAR)) Gafchromic film coronal plane absorbed dose to water...
The aim of this study was to determine the effect reducing number image guidance sessions and patient-specific target margins on dose distribution in treatment prostate cancer with helical tomotherapy. 20 patients who were treated tomotherapy using daily megavoltage CT (MVCT) imaging before served as population. average geometric shifts applied for set-up corrections, a result co-registration MVCT planning kilovoltage studies over an increasing sessions, determined. Simulation consequences...
To determine the relationship between ethical reasoning and gender occupation among a group of male female nurses doctors.Partialist impartialist forms were defined singled out as being central to difference what is known "care" moral orientation (Gilligan) "justice" (Kohlberg). A structured questionnaire based on four hypothetical dilemmas involving combinations (health care) professional, non-professional, life-threatening non-life-threatening situations, was piloted then mailed randomly...
