Electrical capacitance tomography technique reconstructs dielectric constant distribution in an object by measuring the capacitances between the eletrode pairs which are mounted around this object. Because of the limitation of measurement condition, the measured data are imcomplet. This paper describes a multiresolution reconstructive algorithm which is(More)
In order to accurately extract the ultrasound ventricular contour, an adaptive contour extraction algorithm based on a kind of active contour model was put forward against the shortcomings of the traditional GVF snake model that was difficult to converge to the deep concave edges and noise sensitivity. The algorithm was based on the traditional GGVF snake,(More)
