1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. 1. Mobile radiography | Using transportable radiographic equipment to allow imaging services to be brought to the patient | 2. | 3. 2. What is the range of kilovolt (peak) (kVp) for a mobile radiographic machine? | Settings differ among manufacturers, but kVp ranges from 40 to 130. By comparison, a stationary unit can reach up to 150 kVp or more. | 4. | 5. 3.Two categories/classifications of mobile x-ray machines | battery operated and capacitor discharge -- depending on the power source | 6. | 7. 4. What is a Capacitor? | A device that stores electrical energy. It is the power behind the capacitor-discharge mobile x-ray units. | 8. | 9. 5. Name 3 important technical matters must be clearly understood in Mobile Radiography? | the Grid, the anode heel effect, and the source-to-image-receptor distance (SID). Also, exposure technique charts must be available. | 10. | 11. 6.Most focused grids used for mobile radiography are what type? | a ratio of 6:1 or 8:1 and a focal range of about 36 to 44 inches -low ratio, high frequency | 12. | 13. 7. The anode heel effect is more pronounced with the following | Short SID, larger field sizes, small anode angles | 14. | 15. 8.Source-to-skin distance (SSD) cannot be less than _____________ in accordance with federal safety regulations | 12 inches | 16. | 17. 9.A standard brake for a mobile unit. It stops the machine instantly when the push-handle is released | Deadman brake | 18. | 19. 10. Grids used for mobile radiography are often of the __________ type | Focused All focused grids have a recommended focal range, or radius, that varies with the grid ratio | 20. | 21. 11.The anode heel effect is more pronounced with the following: | Short SID, larger field sizes, small anode angles |
