WebMar 23, 2024 · CT dose index (CTDI) measured in mGy standardized measure of dose output best used to compare CT scanners not a measure of absorbed dose or effective dose CTDI vol CT dose index that measures radiation per slice of tissue using a reference phantom only takes into account scanner output and therefore not a measure of … WebThe series list, CTDI vol, and DLP are es-sential when estimating the dose of a CT study. The CTDI vol was developed as a metric to quantify the radiation produced by the CT machine during scanning. It is neither the ef-fective dose nor the absorbed dose from CT to a patient. It is a weighted dose (i.e., average dose)to a CTDI phantom. This ...

Assessment of the Radiation Dose during 16 Slices CT Examinations
Der CTDI ist eine Messgröße in der Dosimetrie und Grundlage für die Berechnung der Strahlenbelastung während einer Röntgenaufnahme mit Hilfe eines Computertomographen. Die Abkürzung steht für "Computed Tomography Dose Index". Im Gegensatz zu anderen Verfahren der diagnostischen Radiologie wird der Patient während einer computertomographischen Untersuchung von allen Seiten angestrahlt. Der Röntgenstrahl ist au… WebFeb 1, 2016 · Between 2010 and 2014, the median CTDI vol ranged from 4.9 to 6.2 mGy and the 75th percentile from 9.7 to 10.2 mGy. There was no significant change in CTDI vol between reporting years (repeated-measures ANOVA, P = 0.985). Conclusion: The 75th percentile CTDI vol reported in this work was 9.8 mGy averaged over all reporting years. WebJan 19, 2011 · We also found that the point dose measurements with standard CT phantoms can estimate the CTDI within 3% difference compared to the full integrated CTDI from the MC method. This study showed the usability of CTDI as a dose index and DLP as a total dose descriptor in CBCT scans. PACS number: 87.57.uq I. INTRODUCTION dwr physio
