Computed Tomography Dose Index - an overview

WebMar 23, 2024 · 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 z-axis (the long axis of the patient). 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 ps4 kingdom hearts theme https://gkbookstore.com
