Imaging, biomechanics, prosthetics, and diagnostic modelling
Medical technology simulations model the physics and computational methods underlying medical imaging and therapeutic devices. MRI k-space simulations fill a 2D Fourier-space matrix with encoded spin-echo signals and apply an inverse FFT to reconstruct the image, showing why motion artefacts appear as ghosting along the phase-encode direction. CT back-projection simulations assemble cross-sectional images from sinogram data using filtered back-projection.
Ultrasound beam-pattern simulations compute the pressure field of a phased-array transducer using Rayleigh–Sommerfeld diffraction, showing how beam steering and focusing are achieved by applying time delays across elements. Prosthetic limb biomechanics models compute ground-reaction forces and joint moments during gait cycles, informing socket-interface and actuation design. These simulations are used in biomedical-engineering curricula and medical-device R&D programmes.
Each simulation in this category is built with accuracy and interactivity in mind. The underlying mathematical models are the same ones used in academic research and professional engineering — just made accessible through a web browser. Changing parameters in real time and observing the results is one of the most effective ways to build intuition for complex scientific and engineering concepts.
