The new QA analysis tool provides instant results from MR QA measurements from a uniform phantom, suitable for any volume coil (e.g. head, knee). Step 1: Scan a uniform phantom using the desired pulse sequence. We recommend using a simple spin echo, 256×256 matrix, TE 10-20 ms, TR 500-1000 ms, 5 mm slice thickness, single … More Simple routine MR Quality Assurance
