New Mexico Decedent Image Database: Opening and Viewing Image Data (Webinar)
October 21, 2020
National Institute of Justice (NIJ), U.S. Department of Justice
Forensic Technology Center of Excellence
1:00-2:00 p.m. ET
Participants will learn about the image data included in the New Mexico Decedent Image Database.
Post-mortem computed tomography (PMCT) scanning was performed on each decedent included in the database.
The resulting image data can be downloaded in DICOM format.
The image data for individual decedents is divided into a series, each of which consists of a stack of two-dimensional images (slices) that represent a particular anatomic region (i.e. the head, neck and upper extremities, the torso, or the lower extremities).
Detailed Learning Objectives:
- Participants will learn about the image data included in the New Mexico Decedent Image Database
- Participants will learn how to open and view DICOM image series and to recognize the difference between soft tissue and bone reconstructions.
- Participants will also be introduced to the Hounsfield Unit (HU) scale, the quantitative gray scale values that correspond to the density of each type of tissue in the image.
- Finally, participants will learn to perform basic quantitative measurements on 2D images, such as measuring distance, circumference, angle, or area, and how to determine the mean HU value of a selected region of interest (ROI).
Funding for this Forensic Technology Center of Excellence event has been provided by the National Institute of Justice.
