A Matlab-based package for automatic analysis of phantom images was developed. The package analyzes images of the American College of Radiology (ACR) phantom, performing measurements similar to those required as part of the ACR accreditation program along with other useful measures. Analysis of the data from five 1.5T MR systems acquired during weekly QA scans was performed. Such data can be help to identify potential system problems, such as lower than usual SNR, and serve as an adjunct to a regular program of quality assurance.
