Added a hidden filter for max and min acquisition CTDIvol. I should be able to use this to create links from CTDIvol histograms to the associated data. References issue #224. As an aside, I think it may be worth letting the user choose which filters are hidden. 2020-12-08 · For collimations that equal or exceed 100mm (or the ion chamber length), the CTDIvol should be determined by using 100mm (or the ion chamber length) in lieu of NxT in the calculation. Example for a 100mm ion chamber: When filling out the CTDI calculation form, any N and T that give a product of 100 would be acceptable, i.e.

In the past CTDI100 (measured over a 100 mm long ionization cham • For Adult, if the cumulative CTDIvol for any given body part exceeds 650 mGy – Scans with table movement (any axial or helical scan) • For Pediatric, if the cumulative CTDIvol for any given body part exceeds 200 mGy • For Adult, if the cumulative CTDIvol for any given body part exceeds 250 mGy CTDIvol in Context of AEC • When Tube current modulation is used: – CTDIvol reported is based on the average mA used throughout the scan – Essentially the CTDIvol at that kVp, bowtie, collimation, rotation time and then using the average mA (CTDI is very linear with mAs) Summary data for CTDIvol are shown in Table 3 below. In every case except adult abdomen exams in 2003, both the average dose and the standard deviation fell for each consecutive year. Thus, the establishment of CT reference levels in the United States appears to have helped reduce both the mean dose and the range of doses for these common CT CTDIvol (or CTDI volume) represents the dose for a specific scan protocol which takes into account gaps and overlaps between the radiation dose profile from consecutive rotations of the x-ray source. Therefore CTDIw represents the average radiation dose over the x and y direction whereas CTDIvol represents the average radiation dose over the x For each different protocol the CTDIvol, minimum mA, maximum mA and patient size where determined for at least 40 patients, along with information on when the mA had reached its specified minimum or maximum value. Plots were made of the CTDIvol versus patient size and of the maximum and minimum mA versus patient size. CT Dose Reporting: Starting on July 1, 2012, new California legislation requires that specific CT scanner dose metrics be included in the radiology report, for all patients undergoing diagnostic CT scans.
Each GSI Recon specifies reconstruction parameters for one image series. Several GSI Recons are preloaded onto the scanner, but the user can define new GSI Recons. Over 46 kg—100 kV, 55 QmAs, CTDIvol 1.83 mGy.

Poster: "EuroSafe Imaging 2020 / ESI-12123 / Low-dose paediatric cardiac CTA examinations and acceptable image quality - mission possible" by: " D. Kostova-Lefterova Pediatrics are more vulnerable to radiation and are prone to dose compared to adults, requiring more attention to computed tomography (CT) optimization. Hence, diagnostic reference levels (DRLs) have been implemented as part of optimization process in order to monitor CT dose and diagnostic quality. The noise index has recently been endorsed to be included as a part of CT optimization in the 2017-08-28 · max compared with no ×Sharp.
