摘要： Disclosed is a method for reconstructing an X-ray CT (computerized tomography) image. The method includes acquiring projection data by means of irradiation of X-rays on a target object at a position close to an X-ray generator such that a portion of the target object including a local region of interest exists within a range of irradiation angles of X-rays, calculating virtual projection data on the assumption that the X-rays are irradiated on the entire target object at the close position, based on projection data acquired through irradiation of the X-rays on the entire target object at a position where the entire target object exists within the range of irradiation angles of X-rays, combining the virtual projection data on the entire target object except data on the local region of interest with the projection data acquired at the position close to the X-ray generator, and reconstructing the combined projection data.

Also, a universal connecting member is made in the cable for connecting to an electrode, so that various shape of electrodes are capable of being coupled to the main body of medical treatment apparatus. The compactness of the medical treatment apparatus reduces the cost for manufacturing and the patient is allowed to easily recognize the state of himself (or herself) during biofeedback therapy, thereby making the therapy efficient.

ROI projection data of a high resolution for a set ROI may be acquired, and the binning technique may be applied to non-ROI projection data created by the X-rays emitted onto a non-ROI region to acquire low-resolution data. Thereby, the amount of projection data may be reduced.

摘要： A magnetic resonance imaging (MRI) system includes a computer for performing overall control and signal processing, a pulse generator for generating a predetermined RF pulse signal and a gradient field pulse signal having variable intensities, a main magnet for generating a static magnetic field, a gradient field coil having a cylindrical dish-like structure surrounding a magnetic pole of the main magnet for generating a gradient field based on the gradient field pulse signal, an RF coil for transmitting a RF field according to the RF pulse signal to an imaging object and receiving MR signals from the imaging object, and an analog-to-digital converter for converting the MR signals from the RF coil into digital signals and outputting the converted digital signals to the computer. The influence of the reverse magnetic field generated from the reverse circulation portion of the gradient field coil is reduced whereby the linear gradient field region and an image region thereof are enlarged, and gradient field coils can be attached stably to magnetic poles whereby vibration and noise are reduced.

摘要： The present invention relates to an electric circuit having a transformer capable of functioning as a buffer inductor, and a magnetic stimulator using the transformer. The electric circuit of the present invention includes a power supply unit, and rectification means for rectifying current from the power supply unit. A transformer has an inductor on a primary side connected to the power supply unit. A capacitor is connected to an inductor on a secondary side of the transformer. Reverse flow prevention means is connected in series between the capacitor and the transformer to prevent charges stored in the capacitor from reversely flowing toward the transformer. A discharge inductor receives charges stored in the capacitor as discharge current and forms a magnetic field. First switching means turns on or off flow of the discharge current that flows in one direction. Bypass means causes current to flow in one direction.
