‘Why are Ultrasound Machines So Expensive?’ and the Future of Ultrasound
Dr. Graham Jenson from New Zealand asks, “Why are Ultrasound Machines So Expensive?” and breaks down some of the reasons why, with links to homemade transducers and thoughts on the future of ultrasound.
Name a technology that is more useful, more educational, more interesting, and more overpriced than a ultrasound machine. You can look inside of living things without the need for a powerful magnets or radioactivity and it is basically made from a speaker and microphone outputting to a screen.
Creating any device for medical purposes can be incredibly expensive, but this ignores all the other uses that ultrasounds can have in education, imaging, sports training and just for fun. The catch 22 is that ultrasounds will never be used for these activities if they are difficult to use and expensive, and they will never become cheaper unless the ultrasound market becomes larger than just health.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
