the lowest possible amount of radiation dose to the subject (e.g. a relatively low dose protocol) that retains the quantitative accuracy of corrections for attenuation. Technologist The key CT acquisition mode parameters (kVp, mAs, pitch, and collimation) shall be set as specified by study protocol and used consistently for all subject scans. Parameter Actor Requirement DICOM Tag Technologist A team comprising a Technologist / Physician / Medical / Physician / Physicist shall ensure that CT techniques protocols are Medical designed such that dose exposure is the lowest radiation dose Physicist necessary to achieve the objective. Protocols defined by Gently and Image Wisely should be CT Technique: Protocol used where feasible. Design The protocol shall be recorded and documented. Technologist The Technologist shall ensure that CT dose exposure is the lowest radiation dose necessary to achieve the objective . The technologist shall ensure that the CT dose conforms to the dose prescribed by the supervising physician or protocol. 3.6.2 Ancillary Equipment 3.6.2.1 Radionuclide Calibrator The following guidelines are collected from ANSI standard N42.13, 2004 and IAEA Technical Report Series TRS-454. All requirements assume measurements on unit doses of I-123 ioflupane and that calibration sources are in the 'syringe' geometry (i.e., no bulk doses). The Constancy test ensures reproducibility of an activity measurement over a long period of time by 698 measuring a long-lived source of known activity. The Accuracy test ensures that the activity values determined by the radionuclide calibrator are correct and traceable to national or international standards within reported uncertainties. The Linearity test confirms that, for an individual radionuclide, the same calibration setting can be applied to obtain the correct activity readout over the range of use for that radionuclide calibrator. Parameter Actor Requirement DICOM Tag Technologist Shall be evaluated daily (or after any radionuclide Constancy calibrator event) using a NIST-traceable (or equivalent)
