Abstract
Systems and methods are described for capturing images of articles under test and processing the images to automatically detect the failure of a test article. The described methods include optimizing image capture to allow for the use of low cost imaging devices instead of high speed cameras or other expensive equipment. The described methods also include several methods for processing the images to identify the occurrence of a failure event.
Claims47
A system for identifying a failure of an implantable medical device during testing thereof, the system comprising:
- a mock vessel having a lumen for receiving the implantable medical device;
- a pump in fluidic communication with the mock vessel for pumping a fluid through the mock vessel in a pulsatile flow with a pressure cycle;
- a camera for capturing a sequence of images of the implantable medical device;
- a signal processor attached to the a camera for receiving, storing, and processing the sequence of images;
- wherein the signal processor processes the sequence of images to select a set of images taken at a selected time in the pressure cycle of the pulsatile flow;
- wherein the signal processor processes the set of images to identify the failure of the implantable medical device.
