The medical device user manual is an educational resource designed to support parents and carers in guiding young people aged 13-18 through STEM topics. The manual explores medical imaging, specifically MRI scanning, highlighting its importance in medical diagnosis and treatment. The content explains how MRI scanners work, their applications, and the technologies involved. The manual also provides examples of images gained from MRI scanning, showcasing their clarity and detail. It discusses the experience of an MRI scan, emphasizing that Siemens has produced resources to explain the technology and imaging process to alleviate fears. The manual also highlights the use of various technologies for medical imaging, comparing MRI scanning with X-rays, ultrasound, and CT scanning. Additionally, it explores non-medical applications of these technologies, such as ultrasound scanning for examining welded joints and MRI scanning for examining archaeological remains.
MRI Scanning
MRI scanning combines ideas from Biology, Chemistry, and Physics to produce detailed images of the inside of the body.
The Process
When your body is scanned, you lie on a horizontal platform, which carries you inside the machine into a set of coils. These coils produce a magnetic field, which affects the protons in the hydrogen atoms in the water molecules in your body. These are then agitated by radio signals and the responding radio signals from the protons are detected by the scanner, and processed into an image.
Applications
Medical imaging can be used in many different ways, including producing video. The clip shows how an opera singer forms various tones when singing, achieved by taking many images rapidly over time. It also highlights how the process is safer than X-rays and can be used in a wider range of applications.
Comparing MRI Scanning with Other Diagnostic Imaging Tools
There is a range of technologies that can be used to produce images of what is going on inside the body. Each of these applies ideas from Physics to the challenge of finding out what is going on inside the body and all are in use in the health service today.
