While the measured dose index in the previous example with an ionization chamber, CTDIvol, is very dependent on patient size when scan parameters for all three phantoms are identical, the displayed CTDIvol on a CT scanner is independent of changes in patient size by definition. Dose equations for shift-variant CT acquisition modes using variable pitch, tube current, and aperture, and the meaning of their associated CTDIvol Dixon, Robert L. Boone, John M. Both CTDIvol and MSAD are used to approximate average radiation dose within a scan volume.

• Volume Computed Tomography Dose Index (CTDIvol) is a standardized parameter to measure Scanner Radiation Output – CTDIvol is NOT patient dose – CTDIvol is reported in units of mGy for either a 16-cm (for head exams) or 32-cm (for body exams) diameter acrylic phantom – For the same technique settings, the CTDIvol reported for the 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. Researchers used mean volume CT dose index (CTDIvol) to measure average radiation dose and mean effective dose to show the estimated future cancer risk from the full radiation dose received in the • Performs LDCT with volumetric CT dose index (CTDIvol) of ≤ 3.0 mGy for standard size patients (defined to be 5’ 7” and approximately 155 pounds) with appropriate reductions in CTDIvol for smaller patients and appropriate increases in CTDIvol for larger patients; • Utilizes a standardized lung nodule identification, classification and The mean (SD) CTDIvol adjusted for patient size was 2.4 (2.0) mGy and the mean (SD) ED for LCS adjusted for chest diameter was 1.2 (1.1) mSv. Unadjusted mean (SD) values were the same. Distributions of adjusted CTDIvol and ED are in Figure 1 and Figure 2.

CTDIvol is not the dose specific to the patient but a standardised index of the average dose delivered from the scanning series (14, 26, 29).

Another commonly used index is the dose-length product (DLP) which factors in the length of the scan to show overall dose output DLP (mGy*cm) CTDI vol x scan length Computed Tomography Dose Index (CTDIvol), in mGy according to IEC 60601-2-44, Ed.2.1 (Clause 29.1.103.4), The Volume CTDIvol. It describes the average dose for this image for the selected CT conditions of operation. 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 CTDI 100 (measured over a 100 mm long ionisation chamber) and CTDI w (weighted average of dose across a single slice) were used; for helical scanners in current use, the parameter CTDI vol is the more There are two ways of measuring CTDIvol, using a phantom of diameter 16cm (pediatric), or alternatively - diameter 35cm (adult).

What Is Dose? • Volume Computed Tomography Dose Index (CTDIvol) is a standardized parameter to measure Scanner Radiation Output – CTDIvol is NOT patient dose – CTDIvol is reported in units of mGy for either a 16-cm (for head exams) or 32-cm (for body exams) diameter acrylic phantom – For the same technique settings, the CTDIvol reported for the 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.

The computed tomography dose index (CTDI) is a commonly used radiation exposure index in X-ray computed tomography (CT), first defined in 1981.

DLP is CTDIvol x slice thickness x # of slices. Download Citation | Anomalous Scanner-Reported Values of CTDIvol | Purpose: Significant anomalies in scanner reported values of CTDIvol for stationary table protocols (with aberrant, elevated Both CTDIvol and MSAD are used to approximate average radiation dose within a scan volume. Total scan length along the z-axis is not considered. Therefore, neither provides an estimate of the total dose along a given scan volume. PURPOSE The scanner-reported CTDI(vol) for automatic tube current modulation (TCM) has a different physical meaning from the traditional CTDI(vol) at constant mA, resulting in the dichotomy "CTDI(vol) of the first and second kinds" for which a physical interpretation is sought in hopes of establishing some commonality between the two. METHODS Rigorous equations are derived to describe the 2020-09-11 (CTDIvol) and dose length product (DLP), as defined by the International Electrotechnical Commission (IEC) and recognized by the federal Food and Drug Administration (FDA); The dose unit as recommended by the American Association of Physicists in Medicine”. While these reporting/recording efforts are well-meaning, the only dose metrics currently Meaning : the meaning is anything from the name's write-up that is surrounded by "double quotes" separate search terms with spaces; search for an exact phrase by surrounding it with double quotes; this field understands simple boolean logic.
