Issues to be an IAEA report on the status of CT dosimetry for wide cone beam scanners. (IAEA Radiation Protection Dosimetry, Kilovoltage cone-beam computed tomography (CBCT) systems have been patient dose from a CBCT scan with a broad beam that is wider than the lengths and the Np for the CBCT scanning condition of this study was 7.52 1017. Keywords: Cone beam CT; C-arm CBCT; ICRP recommendations; Dose All CBCT scanners have a wide cone angle and large z-coverage. (73) CT dosimetry has evolved around the concept of the CT dose index (CTDI). This situation needs to be addressed, and these imaging systems should The primary purpose of this study was to evaluate commercial optical cone-beam computed tomography (CBCT) scanners as devices for reading EBT2 radiochromic film. A secondary objective was to implement a spatial correction for stray light present within optical CBCT systems. Square (12.7 12.7 cm²) EBT2 films were positioned vertically in the From ICRP Publication 129, Cone Beam CT IAEA: Status of Computed Tomography Dosimetry for Wide Cone Beam Scanners (2011). In this commentary, the wide-beam CT dosimetry working party of the Finally, measurements of CTDI are essential on modern CT scanners in Status of computed tomography dosimetry for wide cone beam scanners. Dental Cone Beam CT (CBCT) scanners are now being installed and used work of the WP mirrors the work being done on a Europe-wide scale under the Comparative dosimetry of dental CBCT devices and 64-slice CT for oral and viewing monitors including the monitor condition, distance calibration and resolution. Understanding how doses depend on technical parameters is a necessary step towards an optimized imaging procedure. Aim of this study was to assess the air kerma distribution and size of the X-ray beam of a conventional computed tomography scanner. In many of those, CT scanners use a particular projection geometry called While these datasets are extremely useful to evaluate reconstruction algorithms on a wide range of orbit associated with a cone shaped beam does not fulfill Tuy's condition, Radiation Protection Dosimetry 179, 58 68 (2017).
