CAMRT Radiography Practice Exam

Brightness and contrast are considered factors of what?

1. Spatial resolution

2. Image quality

3. Radiation dose

4. Field of view

The correct answer is: Image quality

Brightness and contrast are essential components of image quality in radiography. Brightness refers to the overall intensity of light in the image, while contrast defines the difference in brightness between various regions of the image. Together, they influence how well different structures can be distinguished from one another. High image quality allows for better visualization of anatomical details, which is crucial for accurate diagnosis and evaluation. A well-contrasted image will show clear differentiation between tissues, enhancing the radiologist's ability to interpret the images effectively. Therefore, understanding and optimizing both brightness and contrast directly contributes to the overall image quality, ensuring that diagnostic objectives are met.
