I want to calculate the average of ctdivol Appendix B lists the different Preset Families available on the 160 mm version of the Revolution, and the minimum and maximum values of CTDIvol associated with each Preset Family. 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. 2016-06-01 · So was the CTDIvol of group 1 compared to group 2 (−36%) and 3 (−32%) (p < 0.001). Conclusion Additional shaping of a 150 kV source spectrum by a tin filter substantially lowers patient exposure while improving image quality on un-enhanced abdominal computed tomography for urinary stone disease. Max accepted NS Protocol name # Exams P25 of Max series CTDIvol (mGy) P75 of Max series CTDIvol (mGy) Max CTDI DRL (mGy) CTDI diff P75 of Total DLP (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) AAPM 2011 Summit on CT Dose. The maximum value of the overall dose profile of each examination was compared to five dose quantities, including CTDIvol,sum and SSDEsum by the ACR CT Dose Index Registry, scan length-weighted CTDIvol and SSDE by a CT dose monitoring platform, and "max z location CTDIvol " by a CT manufacturer. The Optimization of CT Protocols Using Plots of CTDIvol and of Max and Min MA Versus Patient Size for Actual Clinical Scans Using Automatic Exposure Control (AEC) June 2013 Medical Physics 40(6):481 WE-C-103-04: The Optimization of CT Protocols Using Plots of CTDIvol and of Max and Min MA Versus Patient Size for Actual Clinical Scans Using Automatic Exposure Control (AEC) Ranallo, F. Szczykutowicz, T. • 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 2020-04-24 · DIR Measure: CTDIVol Max across Scans; Exam Dates From: 1/1/20 to 2/28/20; Query by: RPID; RPIDs: CT ABD PELVIS W IVCON (RPID145) Highlight: 75th Percentile; Click on the image for a better view. The report plots each value of CTDIvol, in mGy, by date. DIR Measure: selects which Dose Index type to chart, e.g. the maximum CTDIvol value across all scans (CTDIvol Max Across Scans), the sum total Dose Length Product for the exam (DLP Total for Exam), etc.

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. The maximum value of the overall dose profile of each examination was compared to five dose quantities, including CTDIvol,sum and SSDEsum by the ACR CT Dose Index Registry, scan length-weighted CTDIvol and SSDE by a CT dose monitoring platform, and "max z location CTDIvol " by a CT manufacturer. 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.

With automAs, the radiation dose varied with head size, resulting in 47.5 mGy average CTDIvol between 39.5 and 56.5 mGy. 93 and 98 percentage exams were scored great than 3 for brain and bone windows, respectively. 2016-06-01 2021-02-25 CTDIvol • Volume CTDI: –patient mAcalculated to achieve this noise level at any scan parameter settings Set min & max mA 26.
