This resource, from the Institution of Engineering and Technology (IET), allows students to investigate the wide range of sophisticated imaging technology available in modern hospitals, and to explore the latest ideas in search-and-rescue robotics.

Students work in small teams to select a method of medical imaging which is appropriate to a particular medical condition, using the medical records of eight patients. The different imaging techniques covered in this activity include: CAT, gamma cameras, MRI, PET, thermology, ultrasound and x-rays.

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.

The activity is supported by other resources in the Brainwaves collection which look at signals and imaging in healthcare, and the videos Mind mapping and Mind Control.

Curriculum links include the electromagnetic spectrum, medical physics, x-rays, brain scans and the applications and implications of science.
