mpReview - 3DSlicer module for multiparametric annotation of the prostate

Key Investigators

Project Description

The 3DSlicer module mpReview (part of the SlicerProstate extension) was previously developed to assist with manual annotation of the prostate and other related anatomical regions. The current state of the module does not use the latest SegmentEditor, and requires that the data be organized and preprocessed in a specific manner on the user’s local machine. The overall goal is to update the module to be more streamlined, and later have the ability to be extended to other regions of the body.

Currently, we have modified the module to allow data to be loaded from the local Slicer database, or from a remote GCP server. The DICOMweb client is used to retrieve studies/series/instances of the user-selected GCP DICOM store. The resulting segments are saved as a DICOM SEG file (user-specific) and uploaded to the server. Using our own instance of the OHIF viewer, the data and the corresponding segmentations can be viewed.


  1. Objective A. Separate the location of the raw DICOM data and the DICOM SEG files.
  2. Objective B. Brainstorm easier ways for multiple users to view their annotations.

Approach and Plan

  1. Implement the selection of two DICOM stores, where one will contain the raw DICOM data and the other the DICOM SEG files.
  2. Discuss how to best view annotations from multiple users.

Progress and Next Steps

  1. The user can select to use the local DICOM database or the remote GCP server.
  2. Annotations are saved as DICOM SEG files to the server.
  3. We can create a second DICOM datastore to store only the segmentations, but cannot yet read the latest saved segmentation DICOM file from it.


Select to use either the local Slicer database or a remote (GCP) server.


Create annotations of the prostate and other anatomical regions of interest, and upload the segmentation DICOM files to the server.


Use our instance of the OHIF viewer to see the updated annotations.
