An electro-anatomical model of the mammalian His/Purkinje system includes a shell simulating the anatomy of at least a portion of a mammalian heart. The shell has a hollow interior and a first port providing an aperture to the interior of the shell. A plug is inserted in the first port so that a surface of the plug is exposed to the interior of the shell. An electrical circuit provides signals to electrodes in the plug which simulate the electrical signals generated by the bundle of His/Purkinje system in vivo. A second port provides access to the interior of the shell for an introducer catheter to locate the simulated bundle of His and to insert a pacing lead therein. The model is useful for developing tools for His pacing and for training users in techniques for implanting His pacing leads.

Disclosed herein are systems, methods, and software for providing a virtual environment with enhanced visual textures and haptic detail. In some embodiments, a texture atlas and UV mapping is used to render virtual objects having multiple textures that can be manipulated in real time. In some cases, UV coordinates are used to provide enhanced haptic detail.

Ultrasound (US) simulation systems and methods are provided, which utilize computer tomography (CT) data to generate US simulation images, offline or online. Systems and methods repeatedly derive and display consecutive US simulation images that correspond to consecutively-derived corresponding US slices (according to the changing locations and orientations of a dummy US transducer mimicking the US transducer with respect to a physical patient model)—that define geometrically US simulation regions. The US simulation images are at least partly derived from CT data using a CT to US conversion model. Acoustic parameters (e.g., tissue density, acoustic attenuation and impedance) are calculated and integrated per pixel, along beams in the US slice, to form the US image. Additional modelling may be used to calculate reflection and scattering and their effects on the image pixels, and enhancements such as animation and flow data may be added.

Disclosed is a 3D physical replica of a cardiac structure or a vascular structure and a method for manufacturing the same. According to an embodiment, a method for manufacturing a 3D physical replica of a cardiac structure comprises: printing an inner mold according to a 3D model of the cardiac structure; casting a biomimetic material on an outer surface of the inner mold; and solidifying the casted material to form the 3D physical replica of the cardiac structure, wherein the solidified material is stretchable.
