|BViewer Release Notes|
BViewer 1.1.u, released 20 Jul, 2017.
BUG FIX: A change was made in the way Dicom data elements are read from a file by BRetriever: If a Dicom element is encountered in a nested element sequence and it has already been read above that nesting level, the nested element is ignored. For example, this prevents the Dicom data for a nested thumbnail image from overriding the values for the primary image. This fixes some image display problems.
BUG FIX: Logic was added to prevent BRetriever from crashing if a Dicom file is encountered where no Modality is specified. An appropriate error message will now be displayed.
BUG FIX: A potential problem was fixed where the RescaleSlope Dicom element was defaulting to 0 if not specified. It now correctly defaults to 1.
BUG FIX: When the .AXT list of exported data values was updated in the last release, the Manufacturer element was inadvertently deleted. This element has been added back to the exported data.
BViewer 1.1.t, released 27 Jun, 2017.
IMPROVEMENT: The BViewer installation procedure was changed so that it always asks the destination folder for the installation.
IMPROVEMENT: The exported .AXT files were changed to increase the patient comments field length to 1024 characters (from 256). The physician notification status was added, and all the fields from the BViewer report tab were grouped together in the .AXT file.
IMPROVEMENT: A pop-up confirmation window was added when clicking the "All-OK" button after already entering interpretation data. Any data previously entered will be cleared when the "All-OK" button is clicked. This provides the capability for the reader to reconsider whether it's OK to erase that data.
IMPROVEMENT: Comprehensive logging of system error messages was added to the BViewer service controller program. Extraneous status checks that always result in logged errors (because the service isn't active) were eliminated. The service controller now operates successfully from a jump drive provided that the BViewer program installed on that drive is started with explicit administrator privileges. This should make BViewer fully functional when installed on and run from an external jump drive.
BViewer 1.1.s, released 4 May, 2017.
IMPROVEMENT: Support was added to handle images encoded in the RGB format. GE equipment has been observed to produce CR images encoded this way.
BUG FIX: A Dicom exception was added for images from Manufacturer = "Xray". These images now display correctly.
IMPROVEMENT: The subject study image window heading was revised to include the "Linear" and "Sigmoid" windowing settings. These buttons were moved from the BViewer Setup tab. A new button was added to this pair called "Not Applied". This removes the application of any windowing specified in an image's Dicom file and displays the raw image with wide open windowing. NOTE: If you click this button and then wish to return to Linear or Sigmoid windowing, you will need to click the "Reset" button first. The layout of some of the commonly used buttons in this window heading was reshuffled to make room for the new buttons, and some buttons were given enlarged labels to improve readability on high-resolution display panels.
BUG FIX: A Dicom exception was added for modality CR images from Manufacturer = "Agfa" with VOI_LUT image processing. These images now display correctly.
BUG FIX: A problem was fixed for some types of images where scrolling the mouse with the right button down resulted in a previous image re-displaying outside the borders of the current image.
BUG FIX: Some problems were fixed when the display mode resorts to using the Microsoft Windows native OpenGL version. This is the display software used on systems without OpenGL support by the system's graphics controller. It is also intentionally invoked to handle the GE RGB images.
BUG FIX: A situation was observed on 10-bit display systems where the selected image does not display until certain mouse activity occurs. This was fixed by forcing a screen refresh immediately after rendering the image.
IMPROVEMENT: The display refresh rate was increased by a factor of 4. This results in a crisper performance when adjusting the windowing by moving the mouse around with the right button down.
