Magnetic acquisition, removing the noise and increasing the accuracy

Magneticresonance imaging (MRI) is one of the most powerful and effective tool in the fieldof medical imaging. The medical visual diagnostic is very important and widelyused in the analyses of the human health and diseases. Storage or reproductionphases of processing, acquisition, preprocessing, compression, and transmissionare responsible for degradation of MRI. After the acquisition, removing thenoise and increasing the accuracy of the clinical diagnostic system,post-processing, de-noising, and enhancement techniques are suitablealternatives.

The Gaussian noise distribution is transformed into a Riciannoise distribution in order to transform the MR image from complex to magnitudeThemain reason of that is the unavoidable presence of noise and a variety ofartifacts in the medical images. This justifies our research and observation ofthe filtration?s methods of one of the widely used medical imaging – MRI.MRIis primarily used to demonstrate the pathological or other physiological alterationsof living tissues. It provides information that differs from other imagingmodalities such as ultrasound and computed tomography (CT). Its majortechnological advantage is that it can characterize and discriminate amongtissues using their physical and biochemical properties.MRIproduces sectional images of equivalent resolution in any projection withoutmoving the patient. The ability to obtain images in multiple planes adds to itsversatility and diagnostic utility and offers special advantages for radiationand/or surgical treatment planning. MRI is limited only by its spatialresolution and long imaging times.

Theinherent exibility of MRI also permits its application in many clinical tasksother than imaging static anatomy. Recently, the important applications havebeen proposed including imaging blood vessels without contrast agents,measuring diffusion in tissue, measuring tissue temperature, cardiac imaging,dynamic imaging of the musculoskeletal system, liver and reticuloendothlialsystem. In fact it has a various advantageous features, such as high-resolutioncapability, the ability to produce an arbitrary anatomic cross-sectionalimaging, and high tissue contrast.

Unfortunately, there are many potentialsources of image artifacts associated with the technology of MRI.
