Q.Comment on the recent advancement in medical diagnosis and therapy.

Step 1 (Framing). Medical instrumentation has widened the human life span because diagnosis and treatment are now technology-integrated, and this modernisation is possible only because of the efficient application of fundamental physics -- a claim the book backs with a discovery-by-discovery timeline from Roentgen's 1895 X-rays to Townsend and Nutt's 1998 fused PET-CT/PET-MR imaging.

Step 2 (Diagnosis-side advances). Virtual reality stops the brain from processing pain and cures soreness in hospitalised patients, and lets surgeons plan operations on 3D models beforehand; it also helps treat autism, memory loss and mental illness. Health wearables, combined with AI and big data, continuously track a wearer's vital signs to support diagnosis, treatment, monitoring and prevention. Wireless brain sensors monitor intracranial pressure and temperature and then simply dissolve into the body, avoiding a second surgery just to remove them.

Step 3 (Treatment-side advances). Precision medicine customises treatment to each patient's own genes, environment and lifestyle instead of applying one standard protocol -- the book's own example matches different patients' mutations to different drugs. Artificial organs are engineered devices or tissues that interface with or replace a natural organ so the patient can return to a normal life sooner. 3D printing lets audiology, dentistry and orthopedic devices be built to match one patient's exact anatomy. Robotic surgery overcomes the limits of earlier minimally-invasive procedures and enhances a surgeon's capability even in open surgery. Smart inhalers use Bluetooth to detect use, remind patients to take medication, and gather data that helps guide ongoing asthma care. …
