The integration of geophysical techniques into medical imaging is reshaping diagnostic practices, offering unprecedented accuracy and non-invasiveness. This paper explores how methods originally developed for Earth sciences, such as electromagnetic and acoustic wave propagation, are now transforming medical imaging and diagnostics. Traditional imaging techniques, including X-rays, CT scans, and MRI, have provided valuable insights but are often limited by resolution and invasiveness. By leveraging geophysical principles, medical imaging is evolving with techniques like MRI—rooted in nuclear magnetic resonance (NMR) from geophysics—and Electrical Impedance Tomography (EIT), mirroring electrical resistivity methods. Acoustic methods, such as ultrasound and photoacoustic imaging, further enhance diagnostic capabilities. Case studies illustrate the application of these techniques in brain, cardiovascular, and cancer imaging, highlighting their superior resolution and non-invasive nature. Future advancements include emerging technologies like quantum imaging and portable diagnostic devices, promising even greater innovations. This interdisciplinary approach underscores the importance of collaboration between geophysicists and medical professionals to push the boundaries of diagnostic accuracy and patient care.
