  • This feature is an enhancement of image registration feature introduced in version 4.8.2. It guides the user through the process of capturing images, streamlining the workflow.
  • To be able to manage the workflow, the software requires that a pattern of images be defined, which matches a template on the camera itself. These patterns and templates are camera specific and will be supplied on request by Medmont. Patterns for Canon 20D cameras are included in the "Canon_Retinal_EOS_20D_Source-en.mxf" file on installation CD and are also available at Medmont website.
  • Please consult the DV2000 online help or user manual for the details about how to create a mosaic of images.
  A Feature Pack 1 license must be purchased and installed for this feature to work. Please contact Medmont or one of its authorized distributors to purchase this license.
• New Feature - Added facility to view stereo images taken from retinal cameras. Special hardware and Feature Pack 1 license is required for this feature to work.
• Enhancement - Added support for Canon cameras on Vista machines. This only applies to Canon ED sources. Canon 20D and older cameras are not supported.
• On Windows 2003 Server machines WIA service is disabled by default. Configuration tool does not give an error message anymore if the WIA service is disabled. However WIA service needs to be running if a WIA image source has to be created.
• Added back the camera settings menu item to the DirectShow image capture source dialog.
• Exams created via image import mechanism were using the current date instead of the creation date of the file.
  

• Change – Threshold exam pane background color has been changed to black when a color color-key is selected.

• Clear Analysis only cleared analysis for exams that were displayed.
• Clearing Analysis in some circumstances threw NullRefrence exception.
• Difference View threw an exception if one of the exams didn’t have a detectable pupil.

• Enhancement – The image capture interface for Still Image Capture sources has been completely revamped. The view is now a Thumbnail view as compared to earlier slide-show view. User has full control over the layout of this thumbnail view via File->Capture Settings… dialog. Following the same paradigm as all the digital cameras, when an image is captured, user is presented with a review image. The view then changes back to the previous view after certain period of time. User can set the time of review or turn it off completely.
• It is no more a requirement to clear images when user decides to change the eye. Just change the eye from bottom left option buttons. All the captured images are displayed, clearly marked with L or R as they were captured. User can then change the eye via File->Exam Details… dialog, if required.

• Connecting to an M700 with an incorrect serial number now displays this fact rather than an "unable to connect" message.
• Enhancement – Where a system may be connected to different perimeters, ensuring no perimeters are selected will automatically show the selection dialog when the test window is started.
• Enhancement – The Hill of Vision (HoV) computations now extend to the 50-degree ring. This means valid HoV data is available for tests such as the Peripheral test.
• Enhancement – Setting the Lens value for a test is now more versatile. The new rules are modified by the Age-Based Lens (ABL) setting in the test window Options menu.
  • With ABL off, the lens settings are zero when the test window starts.
  • An additional button has been added in the test Lens dialog called Refraction that will copy the patient’s refraction to the test.
  • With ABL on, the lens settings on entry are the algebraic sum of the patient’s refraction and the ABL setting (current behaviour).
  • Any non-zero lens value will bring up the lens prompt before the test can start unless Auto-Prompt is unchecked.
  • Whatever values are used during the test are saved with the test.
  • NOTES:
    • With ABL on, the lens settings will reflect the algebraic sum of the patient’s refraction and the ABL offset. Switching between eyes will reflect these settings. On returning to an eye for which lens settings may have been previously edited, the settings will be arbitrarily reset to the patient’s refraction plus any ABL.
    • With ABL off, any local changes made in the Lens dialog are preserved when switching between eyes.
    • The ABL settings per age group are: 0-30: 0, 31-40: 1.0, 41-45: 1.5, 46-50: 2.0, 51-55: 2.5, 56-60: 3.0, 61+: 3.25.
• In the Histogram display, Pattern Defect now reflects the current Region selection.
• The Spatially Adaptive test now retains any additional points. This allows further exploration of any detected abnormal points and subsequent saving of the test.

• New Feature - Added contact lens designs by RoseK. The program adds RoseK and Graft RoseK designs.
• Enhancement  – The correct procedure for physically transferring an E300 instrument from one computer to another is to also export/import it in the software. If it is installed as a new instrument on other machine its identity cannot be maintained across machines. However sometimes this requirement is ignored in practice. This caused failure to import exams from instruments, which already existed in the database but with a different identity. MS now ignores the new identity and keeps the existing data.
• Attempt to type a value into the radius box of Elevation Settings dialog caused a continuous loop.

• New Feature – Image Registration Feature added.
  • This feature is allows for stitching of a series of retinal images, which are offset a bit from the previous image into a single image. (Also known as MOSAIC)
  • Select the images to be registered and click Edit->Register Images. This brings up the Image Registration dialog.
  • You can arrange the position and stack order of the images in the right hand pane. Click Register and the images are automatically stitched. Save if required.  
• Image Source dialog did not apply the compression settings if the value was typed in the box.
• RGB video sources did not work on FlashBus cards.
• Auto Apply did not work for Invert Black dialog.
• Auto Apply did not work for Separate Color Channel dialog.
• The last remaining image version could be deleted and caused the MS to crash.
• Saving a new Image Version with a lower image quality did not reflect the change although it was saved correctly.

• Canon EOS 20D image operation could not be deleted.
• Enhancement – “Show Active Sources Only” setting on the Image Source dialog is now persistent. 

Medmont Studio

• New Feature – Patient records can now be copied/moved across patients using ‘File->Move Exams…’ menu item. This functionality is useful if you have the same patient listed twice because of some spelling mistakes etc. in a 3^rd party database. In previous versions of Medmont Studio, exams had to be moved individually and there was no facility to copy exams. Now they can be done in a batch. Select all the exams to be moved/copied and click on File->Move Exams…
• While importing exams, if a practice with the same name already exists in the current database then the imported practice is renamed, with a date stamp, to allow for the import.

    • Wavefront error: The difference in optical path length of a ray from an on-axis distant object refracted through the cornea and the principle ray (which passes through the centre of the cornea) to an ideal spherical wavefront inside the eye, divided by 550 nm (the assumed wavelength of the light-ray).
• Added Zernike analysis of height data and wavefront error
  • The values of individual Zernike coefficients are available via the attributes mechanism
  • New graphical views:
    • Height: Zernike Fit: This is a decomposition of the height data in terms of the Zernike components
