What is the purpose of using a rectangular collimator between the round position-indicating device and the patient?
What is the purpose of using a rectangular collimator between the round position-indicating device and the patient?
- To increase the volume of tissue irradiated
- To reduce the effectiveness of the radiation
- To result in a smaller, less divergent beam and a smaller volume of tissue irradiated (correct)
- To produce a more divergent beam
Why is the use of leaded aprons with thyroid collars especially important for children?
Why is the use of leaded aprons with thyroid collars especially important for children?
- Children are more sensitive to radiation than adults (correct)
- Children are less sensitive to radiation than adults
- Children do not need protection from radiation
- Leaded aprons are harmful for adults
What may happen when the apron or collar are poorly positioned?
What may happen when the apron or collar are poorly positioned?
- They have no impact on the image
- They enhance the diagnostic information
- They may appear in the image as a cone-shaped radiopaque artifact (correct)
- They become transparent in the image

Study Notes
X-ray Safety and Equipment
- A rectangular collimator is used between the round position-indicating device and the patient to restrict the x-ray beam to the area of interest, reducing patient exposure and scattered radiation.
Protective Gear
- Leaded aprons with thyroid collars are especially important for children because they are more susceptible to radiation damage due to their smaller body size and higher cell division rate.
- Poorly positioned aprons or collars can result in inadequate protection, increasing the risk of radiation exposure to sensitive areas.
Emergency Procedures
- If no barrier is available during an x-ray exposure, the operator should stand as far away from the x-ray source as possible, behind any available shielding, and minimize their exposure time.
Radiation Biology
- Radiation Biology studies the effects of ionizing radiation on living organisms, examining the interactions between radiation and biological systems.
