A method for suppressing the noise component of a measured magnetic resonance (MR) signal is disclosed. In particular, a signal-space projection operator is produced and employed to suppress the noise component from acquired MR signals that is uncorrelated with the spatial pattern of a desired NMR signal. In one embodiment, an fMRI scan is performed to acquire time course image data. The NMR data is filtered with a signal-space projection operator and reconstructed into a series of image frames. In another embodiment, the signal-space projection operator is employed to suppress lipid signal in MRS image data.

Abstract:
An electrical device and a loop control method are provided. A data signal is obtained from a front end. A variable gain amplifier amplifies the data signal based on a gain value. An analog to digital converter samples the amplified data signal output therefrom to generate a digital data signal. A peak bottom detector detects a peak level and a bottom level of the digital data signal. A threshold controller compares the peak and bottom levels with a threshold value, and generates a first control signal accordingly. An auto gain controller updates the gain value based on the peak and bottom levels with a first step size. The first step size is determined by the first control signal.

Abstract:
The present invention provides a light-enhancing component and a fabrication method thereof by using the focused-ion-beam. In the present invention, the surface plasmon polariton structure is coated on the surface of the optical fiber so as to form the light-enhancing component. When the light passes through the optical fiber, the luminous flux transmitted through the aperture on the surface plasmon polariton is enhanced, and the light beam smaller than the diffraction limitation can be transmitted to the far-field, i.e. the nano-optic sword is formed. The light-enhancing component of the present invention can be used for the optical data storage, the optical microscopy, the biomedical detections and the lithography to perform the extra optical resolutions beyond the diffraction limitation.
