Since the CTDI is normalized to some given length across this direction we need to multiply by the scan length to calculate the dose length product (DLP). This is a nice name as Dose Length Product (DLP) directly describes what the quantity is as it is the product or multiplication of those two terms (DLP (mGycm) = CTDI (mGy) Scan Length (cm).

programmed value (CTDIvol and/or DLP). – Programmed value is set for each scan sequence in an exam – Values can be adjusted according to user preference – Recommendations by the AAPMprovide initial default values (for CTDIvol only)1 – Values were set by AAPM so that notifications would be

Both CTDIvol and DLP had significant correlations with the patient’s age (both r2 = 0.66). There were significant differences between age (7.1 vs. 6.5 years, p < 0.0001), CTDIvol (17 vs. 16 mGy, p = 0.04) and DLP (394 vs 331 mGy cm, p = 0.003) for both estimations of CTDIvol (and correspondingly DLP) •Currently no national nor international standard on which phantom to use.

Digital Light Processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device.It was originally developed in 1987 by Larry Hornbeck of Texas Instruments.While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997. 2017-07-28 Both DLP and LCD systems have excellent image quality, and one is not necessarily better than the other. There are advantages and limitations to each.

DLP is derived from CTDIvol, but incorporates a scan length component.

The median of ED was 10.26 mSv and interquartile range of ED was 7.08-15.03 mSv.

There’s a simpler light path to DLP too, so it’s less prone to internal dust or optical misalignment in comparison to the 3LCD. The LED and DLP Combo Is Recommended: LED DLP projectors are easier to handle because LED tech last longer than traditional lamps. Also, DLP gets more brightness per wattage from the cost-efficient LED compared to lamps. CTDIvol vs.
