Problem

Patexia would like to disseminate the innovation of using motion-layer decomposition imaging techniques for tracking coronary stents during placement. To enter this contest, find a source demonstrating existing commercial use of this improvement to imaging for angioplasty and related surgeries.

Motion-layer decomposition is an image processing technology used to enhance the imaging of faint objects moving in a video (coronary stents, for example, which are barely visible with current imaging technologies). This form of processing involves decomposing the series of video images into layers of objects which move in unison by following the motion of a selected object. Superimposing these images centered on the moving object will give an enhanced image of all the objects which move together in a particular layer. By imaging an easily-visible tool (a radiopaque catheter, for example) and extracting from the video all the objects in the image that move with that tool (a coronary stent, for example), this technique can greatly enhance the visibility of these objects.

The following questions will help clarify the contest and eligible submissions. To be eligible for full prize amount, users should answer “yes” to at least questions 1-3. Additional questions will be used to determine a contest winner amongst multiple entries.
 

  1. Does the source document a commercial use after June 30th, 2000?
  2. Does it capture video (time-series of images) of a device moving with a coronary vessel?
  3. Does it employ motion-layer decomposition of the video? That is, does the usage; a) select features in a moving layer to be imaged (for example, a device with stent), b) follow those features through the time series of images, c) average over the the series of images to obtain an isolated image of the objects desired in a particular layer?
  4. Is it used for stent placement in angioplasty?
  5. Is the moving feature a device such as a catheter, a guidewire, endoscope, angioplasty balloon, atherectomy cutting device, or intravascular ultrasound device?
  6. Is the device marked with a radiopaque marker?
  7. Does the usage include an image intensifier fluoroscope to capture the video?
  8. Does the usage involve injecting a liquid contrast agent into the vessel?
