Digital System Evaluation
|
|
Each digital system to be used for a given trial must be certified by the UW-FPRC before beginning study participant photography. Study specific procedures will determine what digital capture capabilities (fluorescein angiography (FA), color or both) are accepted. Certification begins with submission of the "UW-FPRC Digital System Certification Request Form." Each digital system being certified requires a separate form, however, if both the FA and color capture capabilities from the same system will be used only one form is needed. If a digital system has been previously certified for FA capture capability an abbreviated set of images is typically required to certify for color capture capability (or vice versa). For Zeiss Visupac®, Topcon IMAGEnet® and MRP OphthaVision® systems; one color image (centered on the posterior pole taken at the correct degree angle) is required to verify settings. For Escalon, OIS Winstation® and Digital Health Care: one color and one red free image (centered on the posterior pole taken at the correct degree angle) of a common eye are required. The Fundus Photograph Reading Center accepts images from Topcon IMAGEnet®, MRP OphthaVision®, OIS Winstation®, Zeiss Visupac®, Digital Health Care (DHC), Escalon (EMI) and Heidelberg HRA® Systems.

Topcon IMAGEnet® System Run the Digital System Evaluation software (DSES). If you have any questions during the process please contact Tony Pugliese at (888) 751-0141, tony@cfsimaging.com. Once Tony Pugliese has verified that the system settings are correct he will issue a document to the UW-FPRC. Upon receipt of this document the UW-FPRC will need to verify the system settings by reviewing recent images (taken after Tony’s documentation has been issued). Please see IMAGEnet® Export Procedure to correctly export images to CD.

MRP OphthaVision® System System certification must be handled through MRP. Contact MRP’s Matt Carnevale at (978) 687-7979. Once Matt has approved your system, images (FA and/or color depending on study-specific procedures) will be requested from the UW-FPRC to verify image settings. CD/DVDs sent to the UW-FPRC must include a .dbf and a .tif file. Please see MRP OphthaVision® Export Procedure to correctly export images to CD.

OIS Winstation® System Submit 10 red free images (or color images, depending on study-specific procedures) of 10 different eyes, at the acceptable image angle (determined by camera type). The images must be centered on the posterior pole so that both the disc and macula are in view. If the center of the macula and the center of the disc are not clearly defined they can not be used for calibration. The UW-FPRC would prefer that OIS Winstation® systems have software version 10.0 or higher. All images must be uncompressed. Please see OIS Winstation® Export Procedure to correctly export images to CD. To properly export images to CD:

Escalon (EMI) System Submit 10 red free images (or color images, depending on study-specific procedures) of 10 different eyes, at the acceptable image angle (determined by camera type). The images must be centered on the posterior pole so that both the disc and macula are in view. If the center of the macula and the center of the disc are not clearly defined they can not be used for calibration. EMI systems must have RCPrep software version 1.4 or higher. All images must be uncompressed. Please see Escalon (EMI) Export Procedure to correctly export images to CD. If there are any hardware or software changes made to the system 10 more red free images (or color images, depending on study-specific procedures) may be required to recalibrate the system. This requirement can be abbreviated if one of the 10 eyes used in the initial calibration is from someone who can be photographed in the future (i.e. the same staff member’s eye photographed under 2 different system perimeters). This way if the system changes, the patient can be re-photographed and the old and new photos can be sent to the UW-FPRC for calibration and recertification.

Digital Health Care (DHC) System Submit 10 red free images (or color images, depending on study-specific procedures) of 10 different eyes, at the acceptable image angle (determined by camera type). The images must be centered on the posterior pole so that both the disc and macula are in view. If the center of the macula and the center of the disc are not clearly defined they can not be used for calibration. DHC Classic systems must have software version 4.19 or higher. All images must be uncompressed. If using the DHClient product, please see DHClient Export Procedure to correctly export images to CD. If using the DHC Oculab iP platform product, please see DHC Export Procedure - Oculab to correctly export images to CD. If there are any hardware or software changes made to the system 10 more red free images (or color images, depending on study-specific procedures) may be required to recalibrate the system. This requirement can be abbreviated if one of the 10 eyes used in the initial calibration is from someone who can be photographed in the future (i.e. the same staff member’s eye photographed under 2 different system perimeters). This way if the system changes, the patient can be re-photographed and the old and new photos can be sent to the UW-FPRC for calibration and recertification.

Zeiss Visupac System® Receipt of the "UW-FPRC Digital System Certification Request Form" will initiate contact between the UW-FPRC and Carl Zeiss Meditec Inc. Make sure the serial # of the Visupac system and a phone # to access the system are included. A representative from Carl Zeiss Meditec Inc. will in turn contact the site to arrange a time to go through the certification process. CD/DVDs sent to the UW-FPRC must include .dcm files. Please see Tutorial on How to Measure and Export Images - VISUPAC Digital Imaging and Archive Management System to correctly export images to CD. Questions may be directed to the Technical Support group 1-877-486-7473 or usafundusimaging@meditec.zeiss.com

Heidelberg HRA® System The HRA Classic or HRA 2 systems used at the 30-degree setting are suitable. Eye Explorer® software, version 1.3.5.0 or higher, must be used and the system must have CD writing capability. Heidelberg HRA images must be taken at 512 X 512 or higher resolution. Submit one angiogram saved using the .E2E file format as single images not as a movie image series. Please see Heidelberg Export Procedure Tutorial to correctly export images to CD.
