MIMS 2052 3.3 LO2 Controlling Scattered Radiation

What is the primary purpose of using collimation to control scattered radiation during a radiological examination?

• To increase the exposure time and improve image detail

• To reduce the radiation dose to the patient by limiting the exposed area

• To allow for larger field sizes and cover more anatomy

• To increase scatter radiation and enhance image contrast

Which of the following is a primary benefit of using collimation to control scattered radiation during a radiological examination?

• Enhances patient comfort by reducing examination time.

• Increases the exposure of surrounding tissues.

• Decreases the need for repeated exposures due to patient movement

• Reduces the patient's radiation dose and improves image quality

Which of the following best describes the purpose of using a grid in radiological examinations to control scattered radiation?

• To increase the brightness of the image

• To reduce patient exposure to radiation by limiting the X-ray beam

• To enhance image contrast by absorbing scattered radiation before it reaches the detector

• To reduce the risk of motion artifacts by stabilizing the patient.

What increases the efficiency of a grid?

• Ratio

• Height

• Frequency

• Distance

Air gap technique is usually used for _____ radiography.

The department is assigned an xray test to a patient, but the department unfortunately grids are broken and cant be use. What are other methods that can be use to reduce scatter radiation

• Tube angulation

• Reciprocity Law

• Air-Gap technique

• Using a suitable film speed class

How does compression reduces scatter radiation

• Allows scattered radiation to be absorbed

• Reduce the density of the patient tissue required to penetrate

• Removes any artifact on the patient out of ROI

• Filters low wavelength radiation
