NOTE: As of November 2018, the new home of DICOM4QI is here:

Parametric maps


In this task the participants are expected to demonstrate the capability of the tool to handle loading of the DICOM Parametric Map (DICOM PM) object.

Tasks for participants

  1. Description of the platform/product:

    • name and version of the software used for testing
    • free? if yes - include the download link
    • commercial? if yes - include the home page for the product
    • open source? if yes - provide a link to source code
    • what DICOM library do you use? - if you use certain DICOM toolkit to support this functionality, please list it, if possible

    • Description of the relevant features of the platform:

      • please provide the screenshot of the user interface for the functionality specific to creating/displaying parametric maps
      • how do you communicate parametric map semantics to the user (quantity encoded, units)?
  2. Read task (for each dataset!)

    • load each of the DICOM Parametric map datasets into your platform
    • submit a screenshot demonstrating the presentation of the loaded parametric maps to the user by email to Andrey Fedorov

Note: the screenshots and the DICOM objects you submit will be distributed publicly and included in this document in the Results section.

Test dataset #1

This is a dataset encoding the Apparent Diffusion Coefficient (ADC) map produced by a GE scanner as a DICOM Parametric map object that can be downloaded here. The original ADC map available here was saved as an object of MR modality by the scanner software.

This dataset encodes integer-valued pixels, and the ADC units are micrometers per squared second (as noted in the object).

Test dataset #2

This dataset that can be downloaded here encodes the same ADC map as the first dataset, but in meters per squared second units. The result is an object where each pixel value is less than one. The goal of this object is to test rendering of the true floating point pixels.
