In terms of image quality, what does an increase in SNR indicate?

An increase in signal-to-noise ratio (SNR) is a critical factor in determining image quality in medical imaging, including fluoroscopy. SNR refers to the ratio of the useful signal (the information we want to capture) to the background noise (unwanted signals that can obscure the image).

When SNR improves, it indicates that the useful signal is significantly stronger compared to the noise level. This leads to clearer and more distinct images, allowing for better visualization of anatomical structures and potential abnormalities. As a result, higher SNR values contribute to better image clarity, enhancing the diagnostic capability of the imaging procedure.

Improved SNR also means that the imaging system can produce high-quality images even in challenging conditions, providing clinicians with reliable data for evaluation and treatment planning. Thus, understanding the impact of SNR on image quality is essential for healthcare professionals in ensuring optimal patient outcomes.
