CTDIvol: As you setup the scan parameters from the CTDI or CT Dose Index, which is the current standard for DLP: The DLP or Dose Length Product is the.

The total energy deposted is the dose-length product. DLP = CTDI * scan length. The DLP can be converted into an estimate of the effective dose, which 

CT dose index volume (CTDIvol) is an estimate of the absorbed dose to a "slab" of the patient and is reported in mGy. This estimate comes from data obtained from a CT phantom (click here to learn about phantoms). 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.

Neither one is perfect. So it is  Voltage (kV). CTDIvol (mGy). DLP (mGy.cm). CTDIw (mGy). 80.

• Automated evaluation of CTDIvol and/or DLP before patient scanning using the “Dose Check” feature can help protect patients from inadvertent use of excessively high CTDIvol and/or DLP • Does not negatively impact clinical workflow* • It was designed to prevent egregious errors • It was not designed to “optimize” dose

Choosing Between a DLP or LCD Projector. When weighing your options of DLP projector vs.

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.

DLP is calculated by multiplying the CTDIvol by the length of the patient scanned in cm (mGy*cm). If the patient undergoes more than one scan during the course of a study, the DLPs are simply added together.

The DLP can be used to calculate a rough estimate of the effective dose. 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.

CT dose index (CTDI) (measured in mGy) is a standardised 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 ionisation cham 3-Chip vs 1-Chip DLP. As in all LCD and LCoS projectors, some DLP projectors use three DMDs, one each for red, green, and blue. However, these so-called 3-chip models are very expensive. Fortunately for consumers, there's a less-expensive alternative that uses only one DMD. How can a projector use only one imager?

Essentially, it represents scanner output. DLP is derived from CTDIvol, but incorporates a scan length component. Both function as reasonable proxies for absorbed dose but do not represent the actual patient dose.
