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.

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. N =1 and T = 100mm. CT dose index (CTDI) (measured in mGy) is a standardized measure of radiation dose output of a CT scanner which allows the user to compare radiation output of different CT scanners. 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.

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.

CTDIvol vs. DLP What do they represent? CTDIvol is based on measurements obtained when scanning either a 16cm or 32 cm phantom. Essentially, it represents scanner output. DLP is derived from CTDIvol, but incorporates a scan length component.
