2017-09-19 Can CTDIvol and DLP results tell me two different things? Yes. CTDIvol represents the output when scanning a phantom, while DLP takes into account the scan length. We’ve seen instances where CTIDvol is considered well within a “normal” range but DLP was unexpectedly high. We found the scan settings were appropriate for the study, but the exam length McCollough and colleagues, in their recent editorial in the May 2011 issue of Radiology ( 1 ), have dismissed volume computed tomography (CT) dose index (CTDI vol) and dose-length product (DLP) as useful measures of patient radiation dose, arguing that they do not measure the dose the patient absorbs. However, these indexes quantify the radiation 2015-01-07 Dose length product (DLP) measured in mGy*cm is a measure of CT tube radiation output/exposure. It is related to volume CT dose index (CTDIvol), but CTDI vol represents the dose through a slice of an appropriate phantom. DLP accounts for the length of radiation output along the … DLP Approach to Calculate mSv • DLP approach – DLP comes from scanner •CTDIvol x length of scan – k„s are known •(e.g.

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.

DLP is calculated by multiplying the CTDIvol by the length of the patient scanned in cm (mGy*cm). McCollough and colleagues, in their recent editorial in the May 2011 issue of Radiology (1), have dismissed volume computed tomography (CT) dose index (CTDI vol) and dose-length product (DLP) as useful measures of patient radiation dose, arguing that they do not measure the dose the patient absorbs.

It is related to volume CT dose index (CTDIvol), but CTDI vol represents the dose through a slice of an appropriate phantom.

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.

CTDIvol is used to approximate the radiation dose for each section obtained during a helical scan. It also includes the dose along the z axis of the scan. It is in units of mGy. It is similar to multiple scan average dose (MSAD) MSAD

For example, for a pre-contrast and post-contrast CT of the abdomen and pelvis, the DLPs will be summed. Mean value of CTDIvol and DLP for CCTA was 50 mGy and 825 mGy·cm.

Dose Length Product • The Dose Length Product (DLP) is also calculated by the scanner • DLP is the product of the length of the irradiated scan volume and the average CTDIvol over that distance • DLP has units of mGy*cm What is Dose? 57.

DLP projectors' advantages to better understand which projector type is the best fit for your needs. Choosing Between a DLP or LCD Projector. When weighing your options of DLP projector vs. LCD projector, it can be helpful to look at available features, strengths and your intended use Lung doses correlated with CTDIvol, DLP and SSDE with correlation coefficients(k) at 0.98, 0.93, and 0.99. However, for the cases with CTDIvol less than 1mGy, only SSDE preserved a strong correlation with lung doses (k=0.83), while much weaker correlations were found for CTDIvol (k=0.29) and DLP (k=-0.47).
