FLUG 2017 – IPEM Evidence Based QA Working Party – Fluoroscopy and Fluorography – dosimetry; Mark Worrall

  Background There is little evidence in peer reviewed literature to support the efficacy of many of the tests of x-ray equipment performed routinely by medical physics departments. Current guidance is based on the substantial experience of the members of working parties involved in writing IPEM report 91 and the IPEM report...

FLUG 2017 – A Novel Quantitative Measurement of Image Quality in Fluoroscopy; Patrick Kenny

  Measuring image quality on modern flat panel fluoroscopy systems is challenging. Accurate measurements using the Leeds TO10 must use a small range of prescribed settings of beam quality (kV & added copper). Often these are not always easily achieved on newer systems. Also, TO10 analysis involves estimating the Threshold Contrast...

FLUG 2017 – Digital Angiography: Hunting for Ghosts; David Costello

  Low dose Angiography (LDA) systems rely on significant recursive filtration (aka temporal averaging) to maintain image quality. The use of this type of processing is specific to the imaging application (cardiac, neuro, vascular…) and can be varied by the system vendor. In situations of rapid motion, such processing can have...

FLUG 2017 – Assessment of the detectability of a moving guidewire in fluoroscopically-guided procedures using a mathematical model observer; Nick Ryckx

Presentation to come   Background Fluoroscopically-guided procedures are among the most irradiating medical interventions using ionising radiation. As such, a fair amount of pressure is put on reducing patient dose, either by adapting the protocols implemented in the units, or by heavy technical upgrades allowing for online image processing and subsequent patient exposure...

FLUG 2017 – Development of a software based on an anthropomorphic image atlas for image quality optimization in interventional radiology: initial results for 3D angiography; Michaël Gautier

  Purpose To provide a protocol optimization software helping radiologist to tailor image quality (IQ) in Interventional Radiology (IR) thanks to an anthropomorphic images atlas. Method and materials For the four most representative anatomic areas of our clinical practice (liver, pelvis, lung, spleen), five reference protocols were set-up in our interventional...

FLUG 2017 – Assessment of Fluoroscopy Mode on the Varian TrueBeam Linear Accelerator; Claire Jerrom

  The X-Ray Imaging System on Varian TrueBeam Linear Accelerators can be used to acquire fluoroscopic images to aid radiotherapy treatment planning and verification. Six Varian TrueBeam units were installed in the Radiotherapy Department at Guy's Cancer Centre in June 2016. The fluoroscopy programmes were tested on three of the units...
