Questions and Answers

How does the Heel effect impact image quality?

It causes increased exposure at the anode end, leading to overexposed images
It causes reduced exposure at the anode end, leading to underexposed images (correct)
It causes reduced exposure at the cathode end, leading to underexposed images
It causes increased exposure at the cathode end, leading to overexposed images

What is the Heel effect?

The variation in x-ray wavelength due to the anode angle
The variation in x-ray penetration due to the patient's heel position
The variation in x-ray intensity across the x-ray field due to the anode angle (correct)
The variation in x-ray intensity due to the patient's heel position

How can the Heel effect be minimized?

Positioning the thicker part of the anatomy towards the cathode end (correct)
Increasing the anode angle
Using a larger focal spot size
Decreasing the anode angle

What is the Heel effect?

The Heel effect refers to the uneven distribution of radiation intensity in an x-ray beam due to the varying thickness of the body part being imaged. Signup and view all the answers

How does the Heel effect impact imaging?

The Heel effect can result in a gradual decrease in radiation intensity from the anode to the cathode side of the x-ray beam, leading to variations in image brightness. Signup and view all the answers

Why is the Heel effect important in radiography?

Understanding and managing the Heel effect is crucial for obtaining consistent and accurate radiographic images, particularly when imaging body parts with varying thickness. Signup and view all the answers
