Teledyne QImaging cameras are now part of the Teledyne Photometrics product portfolio. Sharing technology, a common software and being manufactured at the same location, Teledyne QImaging forms the CCD technology section of our scientific camera range. Liver MR Elastography. In a typical liver MR elastography configuration, an active pneumatic mechanical wave driver is located outside the MR elastography room and is connected, by way of a flexible 25-ft (7.62-m) polyvinyl chloride tube, to a passive driver that is fastened onto the abdominal wall over the liver (8,27). Five quantitative MRI techniques were performed: liver MR elastography, spleen MR elastography, liver iron-corrected T1 mapping, liver T2 mapping, and liver diffusion-weighted imaging (DWI, quantified as apparent diffusion coefficients). Two anatomical sequences were used to document splenomegaly, varices and ascites.

The current official release of the driver is 6.4.6, released on September 26, 2011 by Christopher R. Bakercbaker+iwan1394@cs.cmu.edu.
After more than a year of wrestling with the nuances of Microsoft's 64-bit operating systems, and with no small quantity of assistance from a few brave testers (you know who you are!), I am proud to officially release this next version of the CMU 1394 Digital Camera Driver, which includes:

Quantitative Imaging 1394 Driver Test Questions

• Support for all present 64-bit versions of Microsoft Windows XP, Vista and 7, allowing both native (64-bit) and emulated (32-bit) applications to access camera data via a single driver interface.
• A completely new demo application, written from the ground up to support both 32-bit and 64-bit Windows.
• A litany of bugfixes, many of which were contributed by individual users (for which I am grateful!), including:
• Squashment of the nefarious BSOD on resume-from-suspend bug
• A closer-to-correct implementation of the Serial I/O functionality described in the IIDC 1.31 standard (closer = still a little quirky, but the quirks may be in the camera I am testing with)
• Verified Strobe and Parallel I/O functionality (Strobe controls are also now integrated into the same dialog as Gain, Zoom, Focus, etc.)
• .. and many others
• New since the public beta:
  • Fully automated driver installation on 64-bit systems
  • Several minor bugfixes and documentation updates, but nothing that alters the API/ABI

Update: digital signatures for all kernel-mode software

All 64-bit versions of windows require a digital signature via an AuthentiCode certificate in order to run kernel-mode software. I would like to thank MathWorks for providing the funding for this certificate and allowing this driver set to continue to be published freely to the general public. MathWorks provides an adapter to the CMU 1394 Digital Camera driver as part of their Image Acquisition Toolkit to allow developers quick and easy access to images from firewire cameras within the MATLAB environment.

Known issues and limitations

• Large-block asynchronous transfers. I have received several requests and offerance of patches that restore the ability to issue large asychronous I/O (i.e., larger than a single quadlet/register) requests to cameras. I am evaluating these and trying to fold them into the driver in a manner that supports 64-bit platforms.
• Mysterious BSOD when using multiple 1394b cameras on the same bus under Windows 7. In experimenting with various configurations of cameras, 1394b host controllers, and driver settings, I have occasionally triggered inexplicable kernel panics while performing comparatively simple operations. Whether this is a quirk of the new Microsoft 1394 bus driver, of some particular host controller, of the 1394 camera driver's innards, or, most likely, of some combination thereof, remains to be seen. Using a single 1394b camera on a single bus is quite stable, however, and the circumstances where multiple cameras trigger this problem seem rare.
• The usual assortment of bugs and quirks. Much of the frame-handling logic had to be altered to accommodate the curious limitations of DMA transfers on 64-bit systems. Although I have been unit-testing this code to the greatest extent possible, my experience is that no new code is completely bug-free. My thanks go out to the many beta testers who have helped me to this point, and further comments/questions/bug reports/etc. are especially welcome on this front.
