Analysis on improve the image quality of MRI machines based on technical factors

Magnetic Resonance Imaging (MRI) is a non-invasive technology which can produce three-dimensional image of issue. MRI is nowadays widely used to predict of diagnose a wide range of diseases. In this paper, it will be discussed that how can a balance reached among factors time of detection, Signal to Noise Ratio (SNR) and resolution to achieve a relatively best quality of MRI image. Independently, high SNR, high resolution and long-time can all benefit the image quality. However, the former two are inversely proportional to each other and the long-time of detection is beneficial for those two factors but lower the efficiency of diagnosis and the comfort of patients. As a result, it is found out that the time should be adjusted to an appropriate range, approximately in the medium stage of detection, and the resolution and SNR should neither be too high, which are both accurately depend on the practical condition. This paper can contribute to the quality improvement of MRI images as well as raise the efficiency of the process of MRI detection.
