This project is for learning and awareness. It is not medical advice and must not be used to diagnose or treat anyone.
Overview
Build a simple demonstration of shadow imaging and echo ranging to explain two medical scans.
Skills you will use
Materials and tools
- A torch and objects for shadows
- A phone app that measures echo time or a simple ultrasonic sensor
- Poster materials
Step-by-step roadmap
Start
You will finish with: a demonstration and a poster comparing two imaging methods.
- 1
Prerequisites
Nothing special to know first. Then collect the 3 items in the materials list.
- 2
Learn
Read up on medical imaging: medical imaging, ultrasound, X-ray. Your textbook chapter and one short video are enough.
- 3
Plan
Write the brief in three lines: subject, audience and the feeling you want. Collect references and make a shot list, storyboard or sketch set.
- 4
Build
- Show how denser objects cast darker shadows.
- Explain how X-rays use the same idea.
- Demonstrate measuring distance by echo.
- Explain how ultrasound builds an image.
- Compare the safety and uses of each.
- 5
Test
Show a draft to three people from your audience and note where they lose interest or get confused.
- 6
Document
Keep the sketches, drafts and rejected versions; they show your process. Report structure
- 7
Present
Show the finished work first, then the process and the choices you made. Presentation structure
- 8
Publish
Put it online as a portfolio piece with a short write-up of the brief and process.
Expected outcome
A demonstration and a poster comparing two imaging methods.
Other versions of this project
Advanced version
Add how CT and MRI differ.
Ways to do this project
Text marked "You write this" is a prompt for your own work; everything else is specific to this project.
- Problem
- You write thisWrite your question as: How does [what you change] affect [what you measure]?
- Hypothesis
- You write thisWrite it as: If [I change this], then [this will happen], because [reason].
- Variables
- You write thisName the one thing you change (independent), the thing you measure (dependent) and what you keep the same (controlled).
Materials and procedure are in Materials and the Roadmap.
Observation table
You write thisDraw a table with one column for what you change, one for each repeat reading and one for the average.
- Graph
- You write thisPlot what you changed along the bottom and what you measured up the side; use a bar chart for categories and a line graph for numbers.
- Results
- You write thisState what the graph shows in one or two sentences, with numbers.
- Conclusion
- You write thisSay whether the result supports your hypothesis and why you think so.

Questions judges ask
- What would you change if you did this again?
- What was your biggest source of error, and how did you reduce it?
- Where is this idea used in real life?
Use this as the outline of your README or case study.
- Problem
- You write thisThe problem in one or two sentences.
- Why it matters
- You write thisWho has this problem and what it costs them.
- What was built
- A demonstration and a poster comparing two imaging methods.
- Technology
- You write thisThe languages, libraries and tools you used, and why you picked them.
- Architecture
- You write thisOne diagram: the parts and how data moves between them.
- Implementation
- You write thisThe 5 build steps in your own words, with one code or design decision you are proud of.
- Challenges
- You write thisThe hardest bug or decision, and how you got past it.
- Results
- You write thisNumbers: accuracy, speed, users, survey answers.
- Demo and code
- You write thisA link to a live demo or a short video, and to the GitHub repository.
- Lessons learned
- You write thisWhat you would do differently next time.
- Future improvements
- Add how CT and MRI differ.
