IPEM Report 111: Quality Control of Gamma Cameras and Nuclear Medicine Computer Systems is the latest report from IPEM on gamma camera quality control. This report is a major revision of IPEM Report 86: Quality Control of Gamma Camera Systems and encompasses a wide range of new material, reflecting advances in the field over the last decade. Planar performance of a gamma camera is fundamental and this revision sees a complete rewrite of the Assessment of Planar Performance chapter, ensuring it remains relevant for current users. There are also major changes to the material covering software testing, wholebody and SPECT quality control. Importantly, with the now routine provision of combined modality imaging, there is new material covering gamma cameras with CT capability. This will be a must-read for most Nuclear Medicine departments. Looking to the future a chapter of this report is also dedicated to ‘novel’ gamma cameras. Introduced over the past few years these systems have little in the way of published material on quality control testing. Experts from across the UK share their experience with the reader. A final chapter then places each quality control test within the context of a gamma camera’s life span, from equipment specification to decommissioning. This report is thorough and practical, a vital reference for all aspects of gamma camera quality control.
