2246 results about "Observation system" patented technology

An observational system is the way you get information about your program – what it and its participants and implementers are actually doing, and what seems to be occurring as a result. “Observation” here may mean actual observation – watching people, conditions, activity,...

Viewing system having means for processing a sequence of ultrasound images for performing a quantitative estimation of flow in a body organ

A medical ultrasound viewing system for processing a sequence of three-dimensional (3-D) ultrasound images far performing a quantitative estimation of a flow through a body organ comprising means for performing steps of acquiring a sequence of 3D color flow images, of said flow; assessing the flow velocity values in the 3D images, constructing isovelocity surfaces (6) by segmentation of the flow velocity values; computing the volume (Vol) delimited by the isovelocity surfaces; and using the flow velocity value (V) and the volume (Vol) computed from a segmented surface for computing the surface of an orifice (3) of the organ through which the flow propagates. The viewing system further comprises means for performing steps of measuring the peak velocity (VREG) of said flow through said orifice; computing the surface of the orifice (SOR) through which the flow propagates as a function of the flow velocity value (V) at an isovelocity surface upstream the flow propagation with respect to said orifice, the volume (Vol) computed from said segmented isovelocity surface, and the peak velocity of the flow through said orifice. The surface is given by the formula: SOR=Vol. V / VREG. The system can be applied to the assessment of the surface of regurgitation of the mitral jet.
