abstract = "The meaning and the aims of Quality Controls (QC) in Diagnostic
Radiology are discussed, underlining the basic philosophy of
Quality and the difference between the concept of Quality Controls
and Quality Assurance. A brief overview of QC in Computed
Tomography is given describing the main advantages. The methods
are similar in Magnetic Resonance Imaging (MRI) but far more
complex. Therefore only the method for the measurement of
Signal-to-Noise ratio (SNR) is examined in detail while the other
image quality parameters are just mentioned. As an example of a
right method for the evaluation of image quality in MRI, a new
technique for the measurement of SNR based on a spatial
frequencies domain analysis is proposed. Finally some guidelines
for the personnel involved in QC activity are provided.",
