What is another term for image accuracy in the context of computed tomography?

Image accuracy in the context of computed tomography is often referred to as image fidelity. This term encompasses the degree to which the image accurately represents the anatomical structures or tissues being scanned. High image fidelity indicates minimal distortion and a faithful reproduction of true anatomical details, which is critical for accurate diagnosis and treatment planning.

In imaging, fidelity relates closely to how well the resulting image maintains the integrity and detail of the original subject. This includes factors like signal-to-noise ratio, the absence of artifacts, and the ability to resolve fine details.

While image resolution, image contrast, and image sharpness are also important characteristics of CT images, they focus on different aspects. Image resolution refers specifically to the ability to distinguish small structures near each other, image contrast pertains to the difference in density between different tissues, and image sharpness relates to the clarity and definition of edges within the image. Although these factors contribute to the overall quality and accuracy of the image, they do not directly equate to the concept of image fidelity.
