Define 'image resolution' in the context of DXR.

In the context of DXR, 'image resolution' refers specifically to the ability to distinguish fine details within an image. This concept is critical in diagnostic imaging, as a higher resolution means that smaller structures or abnormalities can be detected, providing clearer and more useful images for interpretation by healthcare professionals.

Image resolution is influenced by various factors including the imaging system's sensor capabilities and the technique used to acquire the image. A high-resolution image allows clinicians to see subtle changes or details that could be crucial for accurate diagnosis and treatment planning. Therefore, understanding this definition is essential for anyone involved in DXR, as it directly impacts the efficacy and quality of the imaging process.

Other choices relate to different aspects of imaging, but they do not specifically capture the essence of resolution as the ability to discern detail, which is vital in clinical diagnosis.
