摘要:
When brain images are inputted through MRI (Magnetic Resonance Imaging) and subjected to image processing to assist the diagnosis of brain diseases, functional and morphological images in an ASL coordinate system are inputted from the head of a subject by an ASL (Arterial Spin Labeling) imaging method using an MRI device. The inputted functional images are subjected to mask processing to extract only the region of cerebral parenchyma, and functional images of only the extracted region of the cerebral parenchyma are thereby produced and displayed to be overlaid on the morphological images. In this manner, a functional image such as a perfusion weighted image of only the region of the cerebral parenchyma can be extracted and displayed overlaid on a morphological image.

Provided is a medical image processing device capable of determining a state of an obtained brain image and adjusting the obtained image to suit for performing tissue separation processing. The medical image processing device is configured to select a slice image to be processed as a target slice image from a brain image configured by a plurality of slice images, performs processing for measuring an effective maximum value in the cerebral parenchyma, an effective maximum value in a whole image, and a peak average value around the skull with respect to the selected target slice to determine necessity of high-signal-value-control processing based on the measured effective maximum value in the cerebral parenchyma, the effective maximum value in a whole image, and the peak average value around the skull so that when it is determined that the high-signal-value-control processing is necessary, the high-signal-value-control processing is performed to the brain image.

摘要:
The present invention provides a manufacturing method of a semiconductor module which enables the joining at a low temperature within a short time and can obtain more reliable joining portions by performing the joining without using a solder joining medium. The manufacturing method of a semiconductor module includes a first joining step for joining first circuit electrodes which are formed on a circuit board and back-surface-side die electrodes of a semiconductor die, a second joining step for joining the front-surface-side electrodes of the semiconductor die and one ends of lead frames, and a third joining step for joining another ends of the lead frame and second circuit electrodes which are formed on the circuit board, wherein a low-melting-temperature metal layer is formed on one conductive portion of a pair of conductive portions to be joined and, thereafter, the low-melting-temperature metal layer is heated and pressurized thus diffusing the low-melting-temperature metal layer into the pair of conductive portions by solid-liquid diffusion whereby the conductive portions are joined to each other.
摘要:
A rolling bearing for use in a vehicle, particularly in an electric device on said vehicle, said bearing having a sealing member for sealing urea compound-containing grease, in which an elastic body deteriorates to a low extent when the rolling bearing is subjected to a high temperature and which is capable of maintaining a preferable sealing performance. The grease-sealing member has a rubber molding which contacts the grease. The rubber molding is formed by molding a curable fluororubber composition consisting of a copolymer containing tetrafluoroethylene, propylene, and a crosslinkable monomer consisting of unsaturated hydrocarbon, having two to four carbon atoms, in which a part of hydrogen atoms is substituted with fluorine atoms.
