How to see with sound - Jacques S. Abramowicz
Summary
Bats navigate in darkness using ultrasound waves to create echoes, inspiring humans to develop SONAR technology. Ultrasound imaging is a non-invasive technique applied in various medical assessments, detecting conditions like tumors and gallbladder stones. The process involves emitting waves into the body, creating echoes off solid structures for detailed imaging. During fetal ultrasounds, conductive gel ensures contact with the wand, producing images by waves bouncing off internal organs. Different frequencies are utilized to penetrate to various depths for comprehensive imaging.
Bats' Use of Ultrasound for Navigation
Bats navigate in pitch-black caves using ultrasound waves with tall peaks to create echoes, allowing them to map their environment and inspired humans to develop similar technology like SONAR.
Ultrasound in Medical Imaging
Ultrasound imaging is a non-invasive technique used to evaluate organ damage, measure tissue thickness, detect various conditions like gallbladder stones and tumors. The process involves emitting ultrasound waves into the body, creating echoes off solid structures for imaging.
Fetal Ultrasound Imaging Process
During fetal ultrasound imaging, conductive gel is applied to the skin to ensure airtight contact with the ultrasound wand. Waves pass through liquids but bounce back from solid structures like bones, creating images of internal organs. Different frequencies are used to penetrate to various depths for detailed imaging.
