Cornerstone3D Public Beta
Release
|
|
|
Hello OHIF community!
We're excited to announce the
open-source release of Cornerstone3D
- the future of the Cornerstone.js
framework.
Cornerstone3D has been under private
development through industry
partnership for over a year. After
enhancements and hardening of the
private alpha, we are now able
to open the public beta to the
community. We are looking forward to
receiving your valuable
feedback before settling on the API
for the eventual v1.0 release.

Our goal was to create a renderer
with high-performance
interactivity without sacrificing
memory efficiency in RAM or GPU.
We included an intelligent caching
solution to allow volumes to be
(dis)assembled from individual
image slices as needed to avoid
exceeding the browser tab memory
limit. The new
Cornerstone3D rendering
engine can also:
-
Render all transfer syntaxes
including various compressed
formats such as JPEG2000, JPEG
Lossless
-
Stream the slices of a volume
and interact with them in
real-time as they are being
loaded
-
Display a volume with
orthogonal or oblique
multiplanar reformatting using
GPU-based slicing
-
Visualize the same volume in
different planes (e.g. maximum
intensity projection)
-
Fuse and overlay multiple
volumes, e.g. for PET/CT
fusion
-
Render color images, including
with multiplanar
reformatting
-
Fall back to CPU rendering when
GPU rendering is not available
(currently only for acquisition
direction)
-
Recalibrate the pixel spacing
of the images by modifying the
metadata for the viewport
In addition, we have overhauled
tool support with the following
changes from the legacy
cornerstone-tools library:
-
Migration to SVG-based
rendering for annotations,
resulting in significantly
improved support
for high-resolution
monitors and better overall
rendering performance
-
Improved out-of-the-box
management for cross viewport
tool sharing and
synchronization
-
Improved segmentation support,
with the infrastructure in
place to allow us to
follow the pioneering work of the 3D
Slicer team
and provide polymorphic
segmentation
representations
-
New API for selection,
locking and styling of
annotations
-
A micro-library for calculating Standardized
Uptake Value (SUV) scaling
factors from DICOM metadata, based on
the logic summarized by the
Quantitative Imaging Biomarkers
Alliance
These libraries are all now written
entirely in TypeScript which ensures
type safe API usage and improves
developer experience.

Cornerstone3D's documentation has
been modernized and re-styled under
the OHIF v3 brand umbrella. The new
documentation includes tutorials,
how-to-guides, concepts, and API
references, broken-down into the
following sections:
|
|
-
Getting Started: covers the scope of the
project, related libraries, and
installation instructions
-
Tutorials: provides a series of
tutorials for different tasks
such as rendering, tools,
segmentation
-
How-to-Guides: provides guides for more
advanced tasks such as creating
custom loaders and metadata
providers
-
Concepts: provides an in-depth look at
various technical concepts that
are used in the library
-
Contributing: explains how to contribute to
the project and how to report
bugs
-
Migration Guides: includes instructions for
upgrading from legacy libraries
to the new versions
-
FAQ: provides answers to
frequently asked questions
-
Help: provides information of how
to get help with the
library
-
Test Coverage
Report: provides a detailed report of
the test coverage of the
library
-
Examples: Displays the live examples of
the library
-
API Reference: provides a detailed
description of the API and how
to use each function

The public beta release of
Cornerstone3D is a major milestone
for us, but we're just getting
started with what OHIF can offer.
We're now focused on the next
release of OHIF v3, which will
integrate Cornerstone3D with the
viewer. You can head over to
the OHIF Roadmap Page to see more about our
plans.
