Overview

The first page you will see when the viewer is loaded is the Study List. In this page you can explore all the studies that are stored on the configured server for the OHIF Viewer.

Sorting

When the Study List is opened, the application queries the PACS for 101 studies by default. If there are greater than 100 studies returned, the default sort for the study list is dictated by the image archive that hosts these studies for the viewer and study list sorting will be disabled. If there are less than or equal to 100 studies returned, they will be sorted by study date (most recent to oldest) and study list sorting will be enabled. Whenever a query returns greater than 100 studies, use filters to narrow results below 100 studies to enable Study List sorting.

Filters

There are certain filters that can be used to limit the study list to the desired criteria.

  • Patient Name: Searches between patients names
  • MRN: Searches between patients Medical Record Number
  • Study Date: Filters the date of the acquisition
  • Description: Searches between study descriptions
  • Modality: Filters the modalities
  • Accession: Searches between patients accession number

An example of using study list filter is shown below:

Study Summary

Click on a study to expand the study summary panel.

user-study-summary

A summary of series available in the study is shown, which contains the series description, series number, modality of the series, instances in the series, and buttons to launch viewer modes to display the study.

Study Specific Modes

All available modes are seen in the study expanded view. Modes can be enabled or disabled for a study based on the modalities contained within the study.

In the screenshot below, there are two modes shown for the selected study

  • Basic Viewer: Default mode that enables rendering and measurement tracking

  • PET/CT Fusion: Mode for visualizing the PET CT study in a 3x3 format.

Based on the mode configurations (e.g., available modalities), PET/CT mode is disabled for studies that do not contain PET AND CT images.
