Our counterparts over in the web department recently developed a Flash-based pregnancy calendar. It uses some slick ActionScript 3 and showcases visualizations that our company produced from 3D microscope and fetal micro-MRI data. It’s available for embedding on any third-party site (as we have done on this page). Check it out below.

Not multum in parvo, but Maximum (or Minimum) Intensity Projection.

Download MIP Fuse 1.13

This simple Fuse just takes a range over time and generates an image with the highest or lowest pixels.  Great for normalizing.  It does so for each channel, so it can be useful for color normalization too, or for finding the bounding box of a position pass.  It can also be useful for making “summary” thumbnails of footage.

We’ve seen some pretty cool things at SIGGraph so far…

Gel Sight

Gel Sight is a retrographic surface imaging technique that was wonderfully elegant in it’s simplicity and effectiveness.  They also gave out free samples…

Cuda raycasting 13GB of cryomacrotome goodness (in stereo)

Nvidia had a stereographic interactive realtime rendering of the full 13GB Visible Human dataset being rendered in CUDA on 3 Quadroplexi.  Very impressive.  The glasses used were the new Nvidia active shutter glasses, and were very effective.

Resistive multitouch in many form factors

A new startup out of NYU showed a novel resistive multitouch device.  Very effective, low cost, and suitable to many applications.

UPDATE: Sorry about the broken link, Touchco was bought up by Amazon, so pretty much all of the cool applications they had in mind are replaced by the Kindle 3.

VLC madness courtesy 2 Fusion-io cards

Fusion-io showed their new “budget” nonvolatile storage adapter, the ioXtreme.   $900 gets you 80GB, with a read speed o 700MB/s.  The IO’s aren’t very high, much less their enterprise solutions, but that doesn’t matter if you are reading sequential data.  The booth was pretty crazy, too, one of the better live hardware demos I’ve seen in a while.  I’ll get some pictures tomorrow.  VLC never looked so impressive…

We were recently commissioned to do some visualizations for a virtual colonoscopy procedure.   Also known as a colonography.   If you’re unfamiliar with the process, Wikipedia has enough information to give you a general overview. While there is a lot of information on the internet about the scanning process itself and what the patient will experience, there isn’t much about the ways in which the CT data can be analyzed once it is acquired.  So here’s a brief overview of what we at Anatomical Travelogue did with it.

This past October, I gave a talk for the Engineering in Medicine and Biology Society (EMBS) of the IEEE in New York City. The talk covers the design and evaluation of a device adding 3-D ultrasound scanning to a digital mammography (breast x-ray) system. The presentation centers on the specific application and device, but also touches on more general topics such as stereo image calibration and experimental design for evaluating needle placement accuracy. Note: the video takes a few seconds to buffer and begin playing.

REGISTERED 3-D ULTRASOUND and DIGITAL STEREOTACTIC
MAMMOGRAPHY for BREAST BIOPSY GUIDANCE

Matthew Irwin, MESc

Large core needle biopsy is a common procedure used to obtain tissue samples when cancer is suspected in diagnostic breast images. The procedure is typically performed under image guidance, most commonly using freehand ultrasound or stereotactic mammography (SM). To utilize the advantages of both imaging modalities, we developed a biopsy device combining three-dimensional ultrasound (3DUS) and digital SM imaging with computer-aided needle guidance. This talk will discuss the design of our system, current methods in digital stereo X-ray and 3-D ultrasound imaging and validation experiments using tissue-simulating phantoms. A paper outlining this work was recently published: “Registered 3-D Ultrasound and Digital Stereotactic Mammography for Breast Biopsy Guidance”, M. R. Irwin, D. B. Downey, L. Gardi, and A. Fenster. IEEE Transactions on Medical Imaging, vol. 27, no. 3, pp. 391-401, Mar. 2008.
