Question: 1 / 400

What does the term 'contrast' mean in radiographic testing?

The level of detail in the image produced

The difference in density between areas of the image

In the context of radiographic testing, 'contrast' specifically refers to the difference in density between areas of the image. This variation allows radiologists to distinguish between different structures or materials in the object being examined. High contrast means there is a significant difference between light and dark areas, making it easier to identify the details or variations within the image. Conversely, low contrast results in more uniform density, which can obscure important details.

Understanding contrast is vital for producing high-quality radiographs that effectively highlight the features of interest, thereby enhancing the diagnostic capability of the imaging. The definition encompasses how well different materials or structures can be differentiated based on their radiographic density, ultimately affecting the quality and readability of the radiographic image.
