Our dataset includes whole body CT scans of over 15,000 New Mexicans who died between 2010-2017. Each individual is represented by approximately 10,000 images. Slice thickness is 1 mm with 0.5 mm overlap.

CTs can be viewed using any DICOM viewer, and include normal and thin slice reconstructions for bone, lung, and brain. 3D reconstructions are possible with this data, depending on what viewer you use.

Metadata includes almost 60 variables about the individuals’ demography, life and death. These data are accessible for research separately from the CT scans. Check out the data dictionary for definitions.

2. Search Metadata

Once you have an account, login and search the metadata. Select the variables of interest. There are lots to choose from. Click “Search” to see how many results meet your criteria. The search function can only return 1,000 records at a time, but you can serially limit your search. When you’re ready, click "View Results."

3. Select Records

Once you have an initial search, you can examine metadata for each record to decide if you would like to download the data or request scans. Metadata is accompanied by scout images, which are like large x-rays, to provide a basic view of each decedent. Select records to place in your cart by clicking on the green plus sign. Remove them by clicking on the red minus sign.

4. View Selections

Go to your cart to see the list of records you’ve selected. Click “Download Metadata” to receive a CSV file with the data for the individuals you have selected. Click “Request Images” to submit a research request. Your research request must be approved before you can download CT scans.

5. Request Images

Your research request should describe your inclusion and exclusion criteria, the research you plan to conduct, any specific hypotheses you have, results you expect, and benefits that might accrue. Click “Submit” and your request will be sent to our research committee.

6. Download Images

If your request is approved, you will receive an email describing how to access the scans you have requested.
