In recent years there has been an increasing interest in quantitative analysis of coronary cineangiograms and already for a longer time of left ventricular cin eangiograms. The needfor quantitationofcoronary arterialdimensions has been stimulated by the introduction ofnew therapeutic procedures in the catheteriza tionlaboratory, suchas the balloon dilatationtechnique (PTCA) and thromboly tic therapy, by the need to study the vasoactive responses of pharmaceutical agents, and also by the desire to study the progressive nature ofcoronary artery disease with the ultimate goal to find ways to bring a halt to the progression of coronary atherosclerosis or even achieve regression of the disease. Parallel with these clinical developments, rapid technical developments in computerarchitect ures and semiconductor memories have made it possible to digitize and store cineframesor selected portions thereof in image processors and to analyze these pictorial data quantitatively at affordable prices. More than 15 years of research have been directed by various groups towards the semi- or fully-automated delineation of the left ventricular boundaries on a frame-to-frame basis. Yet not a single system with fully-automated capability is commercially available. In the mean time many different left ventricular wall motion models have been developed, again with little consensuson which model is to be preferred as no golden standard exists.

Sailors trusted him with their money and their lives. That was a mistake. The lucky ones woke up with headaches in the holds of ships headed to China. The others never took another breath. Billy Gohl robbed, 'shanghaied, ' and killed sailors across the Pacific Northwest. Grays Harbor in Aberdeen, Washington was so full of bodies that newspapers dubbed it a 'floaters fleet.' His trapdoor of death was famous. In his time, Gohl murdered over 100 people, making him one of the most prolific serial killers in American history. If you're a fan of Erik Larson's Devil in the White City, Harold Schechter's Little Slaughterhouse on the Prairie, and Truman Capote's In Cold Blood, you'll love Dead True Crime. Ghoul of Grays Harbor: Murder & Mayhem in the Pacific Northwest is part of Dead True Crime, a series of historical true crime stories of serial killers, bizarre cases, and little-known murderers. Meticulously researched short reads, they're the perfect length for a flight, the beach, or a sleepless night. C.J. March brings you a series of tales that will keep you turning the pages deep into the night.
Joe Pickett, garde-chasse dans le Wyoming, surveille un troupeau de wapitis lorsque des coups de feu retentissent. Les animaux sont massacrés les uns après les autres. Joe découvre stupéfait que le tueur n'est autre que le superviseur du district. Il s'échappe dans la forêt enneigée : Joe le retrouve transpercé de flèches et la gorge tranchée. Mais par qui ?...
