Which medical imaging technique? - Practical

Investigate aspects of biomedical signal processing

The use of different types of signals is hugely important in all areas of healthcare. Signal processing engineers are involved in everything from extracting information from the body’s own electrical and chemical signals to using wireless signals to allow search-and-rescue robot swarms to communicate with each other.

Activity info, teachers’ notes and curriculum links
In this practical session students investigate aspects of signal processing. Working in teams, students convert an analogue brain signal into a digital format and transmit it across the classroom to another team using flashes from the LED on the Digital Communicator that they will need to build. The other team will record the digital format and rebuild the original waveform from that information.

This activity can be used as a hands-on extension to the ‘Which Imaging Technique?’ activity (see Related activities section below).

The activity sheet includes teacher notes, guidance, useful web links, and links (where appropriate) to the national curriculum in each of the four devolved UK nations; England, Northern Ireland, Scotland and Wales.
