    摘要： A computer-implemented method of determining one or more target sites usable for treatment of ventricular tachycardia is proposed including receiving three-dimensional model data indicative of a cardiac model modelling an anatomy of a heart of a subject with fibrosis, wherein the cardiac model includes at least one myocardial segment associated with and/or modelled as electrically conducting myocardial tissue and at least one fibrotic segment associated with and/or modelled as insulating fibrotic tissue, simulating the evolution of a cardiac activation wave across the at least one myocardial segment and the at least one fibrotic segment, and determining at least one split location, at which an isosurface of the simulated wave is split into two or more sections, the at least one split location being indicative of a location for the simulated wave hitting a boundary between the at least one fibrotic segment and the at least one myocardial segment.

    摘要： A magnetic resonance (MR) compatible transducer for magnetic resonance elastography applications has a cantilevered drive element a free end of which is arranged in use to move reciprocally, and a flexible non-conductive connection rod slidably disposed within a flexible non-conductive sleeve. The connection rod is affixed at a proximal end to the cantilevered drive element via a proximal flexible connection piece that in use accommodates the slight rotational movement of the cantilevered drive element as it reciprocates about its secured end, whilst translating the rotational reciprocation of the cantilevered drive element into a pure translational reciprocation of the connection rod within the sleeve. The distal end of the connection rod is affixed against a protrusion connected to another cantilevered driven element, upon which is mounted a piston element that in use contacts the subject. The distal end of the connection rod is provided with a distal flexible connection piece that forms the connection between the end of the connection rod and the cantilevered driven element, again to account for the pure translational movement of the rod being converted to rotational movement of the cantilevered driven element about its cantilever pivot point.
