From moon to MRIs: how space research has transformed healthcare, PgII

Key Highlights:

• NASA's space program has produced over 2,000 spinoffs since 1976, benefiting healthcare through commercial products.
• ISRO has transferred over 350 technologies to Indian industries, including health/biomedical sectors, via its Technology Transfer Programme.
• Digital image processing, initially for planetary analysis, is now used in ultrasounds, CTs, MRIs, and mammography.
• Wearable devices for monitoring vital signs are derived from astronaut bio telemetry.
• Satellite-based telemedicine and communication aid healthcare delivery in remote areas and disaster management.
• Space blankets, developed in 1964, are now included in first aid kits due to their ability to reflect infrared radiation.

Detailed Insights:

• NASA technologies have enhanced MRI and CT imaging through advanced digital image-processing, improving tissue differentiation.
• Compact blood analysers and lab-on-chip devices, initially funded for microgravity blood tests, are now used in point-of-care diagnostics.
• Advanced air and water purification systems, designed for spacecraft, are now used in clinical settings for microbial monitoring and sterilization.
• ISRO developed a low-cost heart pump using lightweight rocket material, showing promise in animal trials for treating left ventricle failure.
• Invisible braces are made from translucent polycrystalline alumina (TPA), originally developed by Ceradyne for missile trackers in collaboration with NASA.
• Biomechanical models from astronaut data contribute to the management of osteoporosis and muscle atrophy.
• Telemedicine uses satellite communication for remote consultations, disaster management, and specialist support.

Scientific/Technical Concepts Involved:

• Digital Image Processing: Enhancement of images using computer algorithms to improve clarity and extract useful information.
• Microgravity: Condition of near weightlessness experienced in space.
• Telemedicine: Delivery of healthcare services remotely using telecommunications technology.
• Bio telemetry: Remote monitoring and transmission of physiological data.
