Study Explorer and Image QC Module

Overview​

The Study Explorer in OmegaAI serves as an essential tool for both navigating and managing medical imaging studies, as well as performing detailed quality control checks. This guide provides an in-depth explanation of the functionalities available in the Study Explorer and Image QC Module, focusing on patient information handling, study and series management, and the importation and viewing of various media types.

Components and Functionalities​

  1. Patient Banner and Demographic Information:

    • Overview: At the top of the Study Explorer, the patient banner displays essential demographic information such as the patient ID, confidentiality status, phone number.

    • Expansion for More Details: By hovering your mouse over the patient banner, it expands to reveal additional information. This expanded view is critical for gaining a understanding of the patient's background and the specifics of their associated studies.

  2. Study Cards and Filtering Options:

    • Study Representation: Each patient's study is represented on a study card, which includes the date of the study, the modalities used, and a brief description of the study.

    • Visibility and Filtering: A blue dot indicates the study currently displayed on the screen. Above the study cards, there are three filtering options to tailor the view:

      • Filter to show only the current study.

      • Filter to show only prior studies.

      • A view that displays all studies.

  3. Thumbnail Navigation and Series Management:

    • Thumbnail Details: Each study card shows thumbnails for series and individual images. Thumbnails for multi-frame images display the total frame count.

    • Series Interaction:

      • Hovering over a thumbnail presents three interactive options:

        • A circular checkbox to select the series, which brings up a lower menu for further actions.

        • An X icon to deselect the series.

        • A trash bin icon allows for series deletion by holding the left mouse button until the action completes.

        • A plus (+) icon to initiate the creation of a new study from the selected series, requiring input for the imaging organization and study set.

    • User can easily drag and drop the images to a different study in the Study Explorer to reparent the study.

  4. Loading Series to Viewports:

    • Drag and Drop: Series can be loaded into specific viewports by dragging and dropping them onto the desired viewport.

    • Double Clicking: Alternatively, double-clicking on a series thumbnail loads it into the currently active viewport. This method provides a quick and efficient way to view series without adjusting viewport arrangements manually.

    • Note: When the study is loaded, the first viewport will be automatically selected.

  5. Advanced Options and Importing New Objects:

    • Renaming and Merging: Additional options include renaming series or merging multiple selected studies. An unmerge option is also available for studies created by merging different studies.

    • Import Functionality: New objects such as JPEG images, DICOM objects, PDFs, or RTF documents can be imported by dragging and dropping into the Study Explorer. A dialogue box will appear, offering different handling options based on the file type, enhancing the flexibility in managing study materials.

  • User can click on the delete button on the viewport or within the Study Explorer to delete a frame or a series.

Image Quality Control (QC)

OmegaAI Image Viewer provides a robust set of Quality Control (QC) features that enhance the management and organization of medical imaging studies. This guide will walk you through accessing and utilizing these features efficiently.

Import Images, Videos and Documents​

The QC module also includes a robust image, video and report import feature. This allows you to import various file types by simply dragging and dropping them into the destination study within the Image Viewer.

Supported File Types:

  • JPEG

  • PDF

  • Text

  • DICOM

  • MP4

Importing Process:

  1. Follow the mentioned steps to Access the Image Viewer.

  2. Drag and Drop:

    • Drag and drop the supported file types from your file explorer into the Image Viewer left side panel.

  3. Processing Based on File Type:

    • Text or PDF Files:

      • You can import these as hard copy DICOM objects into the Image Viewer or as study documents into the Document Viewer.

    • DICOM Files:

      • The system checks if the same DICOM series or frames exist in the study. If additional frames are detected, they are added to the existing series. If the DICOM objects belong to a separate series, a new series is created.

    • JPEG Files:

      • You can import them into the same series or as separate series.

Processing Time:

  • The time to process and import files depends on their size.

  • If you navigate away from the Image Viewer screen during the import process, a message will prompt you to confirm whether to cancel or continue the import.

  • After processing, the imported files will be visible in the Image Viewer Study Explorer.
