Check your device’s accuracy and your imaging quality
Due to the importance of quality control in medical imaging, which can increase the quality of diagnosis and, as a result, effective and timely treatment. Therefore, the need to design and develop codified methods in this field is essential. Since the use of MRI devices has grown significantly in the last decade, quality assurance tests are of particular importance to ensure the accuracy of the operation of these devices. In this regard, although the American Association of Medical Physicists (AAPM) has provided guidelines and recommendations, but still a standard and comprehensive standard method is not available as a standard. For this purpose, the design and development of methods for optimizing the quality control parameters of MRI devices along with the construction of relevant phantoms was considered.
to optimizing the specific parameters of MRI devices such as field uniformity, signal-to-noise ratio (SNR), spatial linearity, image uniformity, spatial resolution, section thickness measurement, spatial position and section spacing, as well as artifacts Phase-related image, 5 types of related phantoms were designed and constructed.
