Using the Cine Tool

Overview​

The Cine tool in OmegaAI is designed for real-time viewing of medical imaging studies, such as Ultrasound, CT (Computed Tomography), MR (Magnetic Resonance), and XA (X-ray Angiography). It enables users to efficiently navigate through large multi-frame series without repetitive manual interaction, enhancing the review process. This tool is particularly useful in dynamic imaging where frame-by-frame analysis is essential.

Accessing the Cine Tool​

  1. Visibility and Activation: The Cine tool is available only if the loaded study contains more than two images. It can be accessed:

    • Via the Cine icon located at the bottom of the viewport menu

    • From the toolbar

    • By pressing the "C" key, which serves as a hotkey for quick access

Cine Tool Interface and Functions​

Once activated, the Cine tool GUI (Graphical User Interface) appears with several control options:

  1. Go to First Frame: Jumps directly to the first image of the series.

  2. Move to Previous Frame: Steps back to the previous image in the series.

  3. Play/Stop: Starts or stops the automatic playback of frames.

  4. Move to Next Frame: Advances to the next image in the series.

  5. Move to Last Frame: Moves directly to the last image of the series.

  6. FPS (Frames Per Second) Indicator: Shows the current frames per second rate. FPS can be adjusted by clicking and holding the left mouse button and dragging left or right. The FPS rate is set based on DICOM data for the selected series (active viewport), or a default value is used based on the series modality if no DICOM data is available.

Additional Features​

  • Playback Progress Indicator: An indicator at the top of the GUI displays the progress of the playback.

  • Automatic Playback in Hanging Protocols: As part of the hanging protocols configuration, users can set the viewport to autoplay the cine when a study is opened, facilitating a more streamlined workflow.

Using the Cine Tool Effectively​

  • To enhance workflow efficiency, familiarize with the hotkeys and GUI.

  • Utilize the FPS adjustment feature to match the pace of image review to the specific requirements of the study being analyzed.

Practical Example​

In a clinical scenario where rapid assessment of a cardiac function is required through an echocardiogram, the Cine tool allows clinicians to play through the echocardiogram's image series swiftly, pause at critical frames, or review specific segments repeatedly to ensure accurate analysis and diagnosis.

Shutter Toolset

Overview​

This section guides users in utilizing the Shutter Tool feature in Image Viewer. This toolset aims to enhance the diagnostic process, focus on relevant image areas, and ensure patient privacy.

Shutter Toolset Options​

The Shutter Toolset can easily be accessed via the customized tool wheel.

The toolset has three options to select from including:

  • Rectangular Shutter

  • Circle Shutter

  • Freehand Shutter (can use without having to drag your mouse/cursor)

Enhanced Image Visibility​

The Shutter Toolset allows clinicians to better visualize specific areas of medical images by darkening peripheral, non-relevant regions. This feature allows for more accurate diagnoses.

Reduction of Visual Distractions​

The Shutter Toolset helps minimize unnecessary and distracting elements in medical images, enabling healthcare professionals to concentrate on the critical aspects of the image for diagnosis and treatment planning.

Improved Contrast and Brightness Management​

The Shutter Toolset allows for more effective adjustments in contrast and brightness in isolated regions of the image. This enhancement improves the overall readability and clarity of essential areas.

Effective Annotation and Emphasis​

The Shutter Toolset provides a tool for radiologists and other medical professionals to emphasize significant findings within an image, such as fractures or tumors. This feature facilitates clearer communication and understanding among medical teams and with patients.

Ensured Patient Privacy​

The Shutter Toolset includes a feature to obscure identifiable features of a patientΓÇÖs body that are not relevant to the diagnosis. This feature is particularly important when images are shared or presented in various settings, ensuring patient privacy.

Standardization for Image Comparison​

The Shutter Toolset aids in comparing multiple images by allowing the standardization of visible areas. This feature is crucial for monitoring changes over time in serial imaging.

Diagnostic Accuracy Enhancement​

The Shutter Toolset improves overall diagnostic accuracy by enabling clinicians to focus on pertinent aspects of medical images. This feature leads to more informed and precise medical decisions.
