Title: Method for eliminating streak artifact from image
Inventor: KHOURY ISSA YOUSEF
IPC: G06T1/00
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To eliminate streak artifact by checking each row of an image, locating a row including the streak artifact and replacing it with a row having no streak artifact. SOLUTION: An image is acquired by using an MRI system and also using a pulse sequence. The image is reconfigured and stored as the array of pixel strength values that are arranged in rows and columns in a computer system 107. An operator retrieves the image by an operator console 100, can look at it on a display device 104 and inputs the type of a desirable filtering about a medical image and a filter parameter that commands intensity. Although the prescribed number of rows is automatically selected to eliminate a streak from the image, a number that supports the number of rows of pixels to be replaced is preferably selected. Although the number should correspond to the number of streaks in the medical image, it is possible to increase the number gradually until all streaks are eliminated because processing time is short.

Title: Automatic paper sheet feeding device
Inventor: YOSHIDA NORIKATSU
IPC: H04N1/00
Filed: 1991-12-27
Abstract: PURPOSE:To prevent the double feed of paper sheets by a method wherein a second paper sheet attracted to a first paper sheet owing to static electricity is pulled out from a paper sheet bundle in a state to be accompanied by the first paper sheet. CONSTITUTION:A first paper sheet 14 delivered from a paper sheet bundle 1 by means of a first paper sheet feed roller 3 is delivered to an inputting roller 6 in an image recording device 7. When an automatic paper sheet feeding device is released from paper sheet feeding operation, a felt 18 is pressed against a second paper sheet 15 exposed on the surface of the paper sheet bundle 1 through the force of a left spring 17. Since the second paper sheet 15 attracted to the first paper sheet 14 owing to static electricity is prevented from being pulled out from the paper sheet bundle 1 in a state to be accompanied by the first paper sheet 14, only the first paper sheet 14 is fed to the image recording device 7 and the double feed of the paper sheets to the image recording device 7 is prevented.
