Image quality in an MRI system is assessed through a combination of subjective and objective methods, focusing on factors such as spatial resolution, contrast, signal-to-noise ratio (SNR), and artifacts. Spatial resolution refers to the ability to distinguish between two closely spaced objects as separate entities in the image. It is often assessed using phantoms containing test patterns with varying line spacings. Contrast refers to the ability to differentiate between tissues with slightly different signal intensities. It depends on the MRI pulse sequence parameters and the inherent tissue pr....
