Support for DICOM properties and tags

Comprehensive Support for DICOM Display Properties and Tags

Display any DICOM tag include full support for all pixel data value representations:

DICOM libraries with annotation support

Image Annotation, Mark up, and Redaction

The Medical Viewer provides a robust and flexible API to add annotations to DICOM pixel data and images in HTML/JavaScript applications. These annotation tools are perfect to highlight a region of interest, redact areas and text, and more. Additionally, the control can overlay text to show patient and study information, metadata with configurable weight/importance, and option to permanently burn overlays onto images.

Collaboration and export options:

  • Create, load, save, and share annotations as Softcopy Presentation State including Compound Graphic Objects
  • Upload annotated and processed images back to server as Secondary Capture
  • Save DICOM instances to local archive
  • Generate PNG URL direct links
  • Screen capture
DICOM libraries with DICOM support

Zero-Footprint 3D Volume Rendering

The LEADTOOLS Medical Viewer for HTML/JavaScript apps can render 3D volumes without installing neither software on the client nor using remote technologies such as Citrix. The viewer control communicates rapidly with the server-side 3D rendering engine using standard and well-known web protocols for unparalleled medical 3D display in any modern browser.

  • Multiple volume types including VRT, MIP, MPR, SSD
  • Interactive controls for window level, density removal, offset, scale, zoom, and more
  • Settings and options for customizing the volume appearance including border, rotation cube, resolution, and slicing
  • Caches 3D volumes for faster load times
  • Display 3D reference lines on any series, including optional simultaneous display of boundary lines (first and last)
  • 3D cursor for smooth MPR and synchronized stack navigation

Customizable study and series-level layout

Study and Series Layout

The study and series-level layout in the Medical Viewer control is fully customizable, including:

  • Adjacent cells
  • Any cell location
  • Any cell size
  • Empty cells
  • Overlapping cells
  • Explodable cells
  • Symmetric rows and columns
  • Configurable layout presets
  • XML layout definitions

In addition to completely configurable layout options, the viewer has APIs and properties to:

  • Set various series sorting options
  • Split series into multiple stacks
  • Loads images while scrolling (Lazy Load)
  • Apply image processing and manipulation to a single frame or entire series
  • Study timeline thumbnail preview with drag and drop support
  • Patient laterality, orientation, and localization (Patient Projection)
  • Automatic image synchronization to view multiple series based on the image position and orientation
  • Perform synchronization on two large stacks of the same anatomy
DICOM libraries with hanging protocol support

Structured Displays and DICOM Hanging Protocol

The medical viewer includes a collection of tools to design and reuse display layouts:

  • Intuitive, user-friendly interface to create and store DICOM Hanging Protocols
  • Store study and series-level Structured Displays
  • Design advanced non-grid layout templates (e.g., FMX 18) usable by DICOM Hanging Protocols and Structured Displays

The inclusion of DICOM Hanging Protocols in the LEADTOOLS HTML5/JavaScript Zero-footprint Medical Web Viewer provides developers with an easy way to create a universal, multi-discipline viewer. Few products on the market offer full DICOM Hanging Protocol support quite the way LEADTOOLS does. Developers and integrators are able to create next-generation viewing software for use in large hospitals and enterprises housing varied medical departments (e.g., radiology, cardiology, mammography, dental, etc.), which can all share a single VNA.
