[OA234] Establishing acceptance criteria for VMAT Quality assurance (QA) in a new radiotherapy centre

Comparisons of volumetric modulated arc therapy (VMAT) quality assurance (QA) systems: sensitivity analysis to machine errors

BACKGROUND In volumetric modulated arc therapy (VMAT), gantry angles, dose rate and the MLC positions vary with the radiation delivery. The quality assurance (QA) system should be able to catch the planning and machine errors. The aim of this study was to investigate the sensitivity of three VMAT QA systems to machine errors. METHODS Several types of potential linac machine errors unique to V...

Quality assurance devices for dynamic conformal radiotherapy

Two quality control devices, light-field device and radiation-field device, have been specially designed to facilitate the clinical implementation of conformal dynamic arc treatment (CDAT) and intensity modulated radiation therapy (IMRT). With the devices, the light field as well as the radiation field, projected from the individual beam at any treatment position (i.e. arbitrary gantry angle) c...

Quality Assurance (QA) for Kilovoltage Cone Beam Computed Tomography (CBCT)

Precise targeting of the tumor is very important and imaging can be immensely helpful in this process. Hence the quality assurance of the imaging systems used to guide the beam is also essential. One could argue that it is as critical as quality assurance for the radiation dose output, since the right amount of radiation dose delivered to the wrong location can be as detrimental as delivering t...

Criteria mapping: a method of quality assurance.

Criteria mapping is a flexible and responsive method of chart audit that allows the simultaneous assessment of both the process and the outcome of care by means of health record abstraction. This method of audit is particularly suited to occupational therapy because it includes branching to reflect the sequential judgments of therapists and does not penalize the clinician for omitting unnecessa...
