20090022376 | METHOD FOR PROCESSING IMAGES IN INTERVENTIONAL RADIOSCOPY TO DETECT GUIDING INSTRUMENTATION EQUIPMENT - A method for processing images in interventional radioscopy for detecting guiding instrumentation equipment. The method of the invention enables objects of longilinear or very curved shapes to be detected within the radioscopic image having very low contrast to noise ratios. In one embodiment, an algorithm enables the measured contrast to noise ratio of long or curved structures in the image to be considerably improved. To do this, an embodiment of the invention uses oriented, separable, recursive and rapid steerable detection filters. Said detection filters have a low calculation cost, even for long filters having several orientations | 01-22-2009 |

20080240536 | METHOD OF DETECTION AND COMPENSATION FOR RESPIRATORY MOTION IN RADIOGRAPHY CARDIAC IMAGES SYNCHRONIZED WITH AN ELECTROCARDIOGRAM SIGNAL - A method of detection and compensation for respiratory motion improves the registration between a 3D pre-operation image and X-ray images acquired during a cardiac intervention. By synchronizing the X-ray images with the electrocardiogram, the disclosed method thus eliminates the motion related to the heart cycle from these images, thus isolating the contribution of the respiratory motion. From this point, an algorithm is proposed capable of attributing the motion remaining in the radiography images to respiration. The algorithm also enables this motion to be detected and compensated for in order to obtain a registration between 3D cardiac images and radiography images. | 10-02-2008 |
20090136112 | Method for the processing of images in interventional radioscopy - A method for the processing of images in interventional radioscopy to produce a sequence of de-noised images in which elongated objects of guiding instrumentation equipment are preserved and enhanced. The method of the invention uses a tool for indicating the confidence to be placed in a given pixel as regards its belonging to a piece of guidance equipment. This tool is used to create a combination algorithm capable of re-injecting the pixels having a low contrast-to-noise ratio into the de-noised image. This combination algorithm enables the enhancement solely of the pixels of the guidance equipment with a high confidence value so as not to produce artifacts with the enhancement of false positives. | 05-28-2009 |
20100208973 | RADIOLOGICAL IMAGING METHOD AND DEVICE - A method for radiological imaging of a region of interest including blood vessels. The method has the steps of acquiring a real-time fluoroscopic image of the region of interest by exposing the region of interest to a first dose of X-rays, the fluoroscopic image showing background structures and instrument introduced into the vessels; subtracting a mask image from the acquired real-time fluoroscopic image to generate a subtracted fluoroscopic image showing only the instrument; combining the subtracted fluoroscopic image and a pre-recorded diagnostic image of the region of interest showing only the blood vessels to generate a combined image showing both the blood vessels and the instrument; and displaying the combined image on a screen for viewing. The mask image is determined from a fluoroscopic image acquired prior to the introduction of the instrument into the vessels by exposing the region to an X-ray does equivalent to the first dose. | 08-19-2010 |
20110019878 | SYSTEM AND METHOD TO COMPENSATE FOR RESPIRATORY MOTION IN ACQUIRED RADIOGRAPHY IMAGES - A system and method to compensate for respiratory motion in imaging of instruments introduced into the subject anatomy is provided. The system can include an imaging system in communication with a controller. The controller can include a memory with program instructions for execution by the processor to perform the steps of: detecting an illustration of at least a portion of the plurality of instruments introduced into the subject anatomy in a first image and a second image, comparing and calculating a displacement of the plurality of instruments between the first and second images, calculating one of an average or median displacement of the plurality of instruments between the first and second images, and applying one of the average and the median displacement to adjust at least a portion of the first or second images or a pre-acquired three-dimensional model of the internal region of | 01-27-2011 |

20120271729 | Method and System for Managing Sourcing Program Requests - A method for managing sourcing requests. The method utilizes a computer interface to collect the sourcing request and present that sourcing request to a sourcing agent. The method also utilizes a computer interface to allow the sourcing agent to initiate and conduct a sourcing protocol that provides a list of results from which the sourcing agent can select the most appropriate sourcing solution for an organization. A computer program product comprising a non-transitory computer medium with instructions to collect sourcing request data, determine whether the sourcing program needs modification and modifying the sourcing program. | 10-25-2012 |
