How Ultrasound Works

In this episode, Josh and Chuck dive deep into the fascinating world of ultrasound technology, explaining how it uses piezoelectric crystals that vibrate to create sound waves that bounce back to form images of what's inside your body. Beyond the pregnancy sonograms most people know about, they explore how ultrasound is revolutionizing emergency medicine, cardiology, and even emerging applications like pushing chemotherapy drugs across the blood-brain barrier and levitating objects with sound waves. It's a surprisingly complex and remarkable machine that deserves way more credit than it gets for being one of modern medicine's most important diagnostic tools.
