DLP can be calculated by multiplying CTDI x Scan Length. DLP is also given directly by the scanner. If you wish to calculate yourself, 2020-07-30 CTDIvol is an estimate of the dose deposited in a slab of the patient.It is based off of precise measurements made with a phantom. Every combination of imaging parameters (including strength and quality of x-rays and how fast the table moves through the scanner) is tested for a given CT scanner. 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.

From it I calculated an effective dose (described below) of 5.5 mSv for you. Remember this is a rough estimate; it could be off by 20% either way. 2015-01-07 · The term CTDI (vol), in the unit of milligray (mGy), is a reference value used for the measurement of radiation dose in a plastic cylinder. DLP stands for dose-length product. DLP is the CTDI (vol) multiplied by the scan length in centimeters and is given in units of mGy–cm. 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 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. The term CTDI (vol), in the unit of milligray (mGy), is a reference value used for the measurement of radiation dose in a plastic cylinder.
