摘要： A method for stabilizing and optimizing angiogram cine runs. The method for stabilizing involves reducing abrupt motion from the last frame to the first frame by refining the choice of the estimates of first and last frame indices provided by the user and by performing image registration so that a feature of interest is nearly in the same position between the last and first frame. According to another aspect, a network accessible system for storing and playing back angiographic images and presenting patient information is provided. The most diagnostically relevant subset of frames are extracted from selected cine runs and made available over a wide area network (WAN) such as the Internet. The process of identifying a subset of frames encompassing a few cardiac cycles from the most relevant cine runs makes it possible for authorized users to view the images on a web page interface from remote locations like homes or offices using the Internet which otherwise suffers from bandwidth limitations that restricts the amount of data that can be transmitted within a reasonable delay.

摘要： A catheter assembly especially adapted for injecting therapeutic liquids such as DNA solutions to a patient's myocardium comprises an elongated guiding catheter for insertion through a patient's artery to the vicinity of the myocardium, a reservoir for therapeutic liquid at the distal end of the guiding catheter, one or more injection needles protruding from the distal end of the guiding catheter and in fluid communication with the reservoir, the extent of needle protrusion being appropriate for penetration of but not passage through the myocardial wall, and an operating device for delivering a predetermined quantity of therapeutic liquid from the reservoir through the needles.
