Understand how MRI machines align proton spins, how ultrasound maps tissue boundaries, and how ECG electrodes reconstruct the heart's electrical conduction — all with interactive physics.
Medical Technology is the field where physics, signal processing and biology meet to build the instruments that diagnose and treat patients. In this category you will learn how magnetic resonance, ultrasound, computed tomography, electrocardiography and dialysis actually work — not as abstract theory, but as living models you can manipulate in your browser. Adjust an RF pulse and watch the magnetisation vector tip; change an ultrasound frequency and trade resolution against penetration depth; tune a pacemaker and see the heart respond beat by beat. These principles matter because they underpin modern diagnostic imaging, life-support devices and treatment planning. Building intuition for the maths behind each machine helps students, clinicians and biomedical engineers reason about image quality, artefacts and patient safety.

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.

Common questions about this simulation category
Every Medical Technology simulation on this page turns dense biomedical physics into something you can see and adjust in real time. Each interactive Medical Technology model — from MRI spin dynamics and B-mode ultrasound to ECG synthesis and haemodialysis clearance — is built on the same equations used in clinical practice and biomedical-engineering research. Whether you are revising for a medical physics exam or simply want to learn Medical Technology online, these browser-based tools build durable intuition. A real-world application: radiographers and MRI technologists use these very imaging principles every day to capture diagnostic scans while minimising artefacts and patient radiation dose.
