LCD Display Calibration for Medical Imaging


The Image Systems Advantage...


Critical Accuracy - It is critical that radiology displays present accurate and consistent images. Image Systems provides calibration solutions to ensure DICOM compliance when using our display solutions. Image Systems' CFS is the Calibration Feedback System you need to ensure your displays are calibrated properly.

Calibration Hardware
Integrated Front Sensor

An integrated front sensor is optionally available on Image Systems 2MP, 3MP, and 5MP grayscale LCD displays. The moveable front sensor retracts into the bezel after use and keeps the entire LCD screen viewable. The integrated front sensor option enables hands-free conformance and calibration.		 Image Systems' luminance meter (Puck)

A handheld puck for use with the CFS software. The puck has a USB interface.
SBC Stable Back light Control

The SBC function consists of a back light sensor internal to the display monitor that measures and provides a closed-loop control of the luminance output of the LCD back light. This feature is a standard option on the Image Systems 2MP, 3MP, and 5MP grayscale LCD displays.		 Add-on Front Sensor (AFS)

For LCD monitors that do not have an integrated front sensor, this add-on front sensor attaches to the monitor and provides for hands free conformance and calibration. Connects via USB connector.


Calibration Software

CFS ™ (Calibration Feedback System)


with Network Support*       SPECIFICATIONS:  CFS
The CFS network software is SNMP enabled so that an administrator can view and manage the status of the displays from a remote site. Alarms and Traps for out-of-tolerance conditions are generated.
*Requires additional SNMP console software such as Castle Rock SNMPc Network Manager.

CFS TM (Calibration Feedback System)


with Hands-Free Support      SPECIFICATIONS:  CFS
The CFS software can be used with optional integrated luminance sensors to provide hands-free DICOM compliance testing and calibration. A built-in scheduler can initiate the testing to occur on off-hours. A log of tests is generated providing a verifiable record of compliance testing.
Eliminates or reduces the need for technicians to take manual measurements.

CFS TM (Calibration Feedback System)


with Puck Support                      SPECIFICATIONS: CFS
CFS software can be used with a precise, handheld luminance
meter (puck) to measure conformance per the procedures
described in the ACR/NEMA DICOM standard. A custom Lookup Table can be generated and downloaded at the user site to ensure DICOM compliance.

Test Pattern and DICOM Viewer



Included in the Image Systems CFS software are test patterns for visual confirmation of performance including SMPTE, Briggs, Luminance, and easy access to TG18 DICOM test patterns.  In addition, a simple DICOM viewer is included to enable viewing of medical images and modality generated test images.

Verilum Calibration Software


with Puck Support
Image Systems' cards and drivers have been tailored to support Verilum. The optional Verilum calibration software is successfully being used by many customers to calibrate and measure DICOM conformance. It requires the use of a handheld Verilum puck.
