Part 2: Description
2.4. Licensed Features
The system features are determined by the licensed options selected by each site,
allowing you to invest only in the features you want, as well as add features at a later
date. The following features can be obtained by purchasing the appropriate license:
•
DigitalNow DICOM Export
•
ImageChecker Screen-Film CAD
These features are described further in the following sections.
DigitalNow DICOM Export
With DigitalNow, R2 film-scanning platforms send digitized film images to a
DICOM-conformant archiving system for future review. Sites using full-field digital
mammography (FFDM) systems can scan prior analog studies and compare those
priors with the current digital study on a softcopy review workstation. Sites planning
to move to digital in the future can plan ahead and send the digitized images to an
archive system now, and retrieve them for comparison later to future digital studies.
R2 systems configured with DigitalNow utilize the separator sheet barcode (‘R2 ID’)
for identifying the patient associated with the digitized film images. This allows for
the proper identification, storage, and retrieval of digitized film images in the archive
system.
The system can be configured to produce 50- or 100-micron output images for any
output device. For digitized film images, the processing units perform dynamic
window leveling on each image, as well as blacken image areas that lie outside the film
edges.
ImageChecker Screen-Film CAD
The ImageChecker license provides Hologic’s CAD algorithm, which is used to
identify and mark regions of interest on routine screening and diagnostic
mammograms to bring them to the attention of the radiologist after the initial
reading has been completed.
ImageChecker provides three types of RightOn™ CAD marks (Mass, Calc, and Malc)
that can appear in the results. Each mark identifies a region of interest for the
radiologist to review.
Calc – Marks regions suggestive of calcifications.
Mass – Marks regions suggestive of masses or architectural distortions.
Malc – Composite mark indicates an overlap of Calc and Mass marks.
The CAD marks can be augmented using the EmphaSize™ and PeerView™ features.
