摘要： A computed tomography apparatus and method where data is upsampled with shifting to produce upsampled data. The data is shifted up and down in the same amount in the z-direction, and then upsampled through interpolation. An image is reconstructed using the upsampled data. The process is preferably performed column-by-column. An upsampling shift and interpolation kernel size can be adaptive to the data z-gradient.

摘要： An X-ray apparatus including an X-ray source, a rotation mechanism which rotates the X-ray source about a rotational axis, and an X-ray detector having a plurality of detection elements. A blocking member defining a slit structure is provided between the X-ray source and the X-ray detector. The slits of the blocking member include two rows aligned in a channel direction of the detector elements, and two rows staggered in the channel direction, thereby to obtain a CT image with improved spatial resolution. Alternatively, instead of using a blocking member, some of the detection elements of at least one detection segment are staggered in the channel direction with respect to detection elements of another detection segment.

摘要： A non-volatile memory, such as a flash memory card, using a rewritable non-volatile memory is provided with an improved write-protect arrangement. The non-volatile memory includes a collectively electrically erasable and writable memory (e.g., a flash memory), a reset IC for generating a power-on reset signal upon turn-on of the power supply, and a card controller for performing control between each flash memory device and a memory card interface. The flash memory is set with a write protect save register written with an address of an area desired to be subjected to write protect, the write protect save register belonging to an attribute area, and a protect range is set from the system. Since the address to be write-protected is itself written in the non-volatile flash memory, the address will continue to be stored, even if the power is turned off. A method for software write protection control is also provided.
