Abstract
Systems and methods for laser catheter treatment in a vessel lumen. The method includes inserting the laser catheter within the vessel lumen to a location of a treatment area; presenting an image of the treatment area within the vessel lumen based on using an ultrasound (US) imaging system; and, detecting, in real-time, a bubble cloud that is a function of the laser catheter operation (at a prescribed speed and controlling a fluence and a pulse rate) in the treatment area. The method determines a vessel diameter, a real-time location and measurements of the bubble cloud, and estimates a dwell position and dwell time. A dynamic displayed image that is indicative of a progression of the laser catheter treatment is presented, and commands may be generated to modify the laser catheter parameters responsive to the estimated dwell position, the estimated dwell time, and a recommended treatment protocol.
