Data Flows
This section describes how information flows among the various devices for the Cenova
applications, as listed below.
2.3.1. ImageChecker CAD Data Flow
2.3.2. ImageChecker CAD with DICOM 6000 Data Flow
2.3.3. Hologic Imaging Biomarkers Data Flow
2.3.4. DigitalNow HD Data Flow
Note that mammography systems may have different configurations, depending upon
the devices installed at your site.
2.3.1.
ImageChecker CAD Data Flow
The diagram below shows how information typically flows through systems with
ImageChecker CAD.
m
Note:
ImageChecker CAD also applies to C-View 2D images. Raw C-View images are
sent to the Cenova server. Corresponding Breast Tomosynthesis Image or For Presentation
images are sent to the diagnostic review workstation(s) and PACS.
m
Note:
When both conventional 2D mammography and C-View 2D images are sent to
Cenova for a ComboHD study, the Cenova server will produce separate ImageChecker CAD
results for the conventional 2D mammography and C-View 2D images, respectively.
Image Acquisition System(s)
1, 2, 3:
FFDM systems can be configured to send digital mammography x-ray images to
any device that conforms to the DICOM standard. The FFDM device sends two types of
images, For Processing images to the Cenova server, and For Presentation images to the
diagnostic review workstation(s) and PACS.
Cenova Server
4, 5, 6:
The Cenova server sends results (for example, Mammography CAD SR objects
or CAD SC images) to one or more diagnostic review workstation(s) and/or PACS
devices. The Cenova server can also provide printed results showing the four case-
processed views with CAD marks.
Diagnostic Review Workstation(s) and PACS
3, 4, 8:
The review workstation(s) are configured to receive the For Presentation images
(3, 8) and ImageChecker CAD results (4, 8), which are then reviewed by the radiologist.
7, 8:
The PACS can be configured to send:
•
For Processing images to Cenova (7), which processes the images and distributes
the CAD results according to its configuration, and/or
•
ImageChecker CAD results and/or For Presentation images to the review
workstations (8).
