http://www.netbooknews.com Nvidia’s GTC 2010 opening day Keynote by Jen-Hsun Huang presented a breakthrough development in robotic cardiac surgery called "beating heart surgery". This notable development of minimally invasive surgery [MIS] benefits patients through shortening convalescence, reducing trauma and surgery costs. The aim is to make the surgery more intuitive for the surgeon and safer for the patient. The fact that the heartbeat and respiration represent the two major sources for motion disturbance requires the use of computer vision techniques that accurately sense the motion of the heart which are then used in a feedback control loop mechanism that synchronizes identical motion in the actual surgical elements. The heart then appears as nearly motionless to the attending physician allowing full concentration on repairing defects.
