Extended Field Of View

The purpose of this work was to evaluate computed tomography (CT) simulators used in radiotherapy treatment planning in Serbia, Croatia and Bosnia and Herzegovina. A survey of quality assurance programmes of 24 CT simulators in 16 facilities was conducted. Dedicated CT-to-ED phantom was scanned at 120 kV and 140 kV, to obtain CT-to-ED (ED- Electron Density) conversion curves as well as CTDIvol. Thoracal phantoms were scanned in standard and extended field of view to evaluate dosimetric effect on treatment planning and delivery. Mean age of measured scanners was 5.5 years. The mean water HU value was -6.5 (all scanners, all voltages) and air HU value was -997. Extended field of view CT data differ from standard field of view and differences between conversion curves have significant dosimetric impact. The CTDI data showed large range of values between centers. Better QA of CT simulators in all countries is recommended. CT-to-ED curve could be used as default at one voltage and per manufacturer. Extended field of view imaging can be used, but treatment planning should be avoided in the regions out of standard field of view.
