Title: Imaging device for displaying volume with high quality by real-time three-dimensional reconstruction, and method therefor
Inventor: BANI-HASHEMI ALI
IPC: A61B6/02
Filed: 2001-07-02
Abstract: PROBLEM TO BE SOLVED: To display volume of movement of a specimen in real-time with high accuracy. SOLUTION: This imaging device display the volume of the moving specimen with high quality by a real-time three-dimensional reconstruction. The real-time movement of the specimen is decided by low-quality display of only a portion of the volume. The obtained three-dimensional angiographic image display can be also applied to other methods, such as MR or CT. An mage of the MR, the CT or the like is recorded, together with the three-dimensional angiographic data, so that MR CT images or the like are transferred into the same coordinate frame as for the three-dimensional angiographic image. The movement of the specimen is detected by a two-dimensional X-ray fluoroscopic image and is reconstructed into a three-dimensional mode.

IPC: G02F1/133
Filed: 2001-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a driving method effective for improving the moving picture blurring of a hold type video display device. SOLUTION: The video display device is provided with a display panel 0 arranged in a matrix form and provided with pixels whose brightness change in response to a signal, a row drive circuit 15 connected to each row of the pixels to successively select the pixel in row unit, and a column drive circuit 16 connected to each column of the pixels to write the signal in the successively selected pixel and to display the video for one frame. The column drive circuit 16 is provided with a correction means and a modulation means. The correction means applies correction to the signal according to the brightness difference between a signal written in a previous frame and a signal written in this frame, and thereby uniformizes the response of each pixel.  The modulation means compares a region having a large brightness difference with a region having a small brightness difference, carries out a modulation so that the quantity of corrections applied to the signal is intensified from the large difference region toward the small difference region, and thereby suppresses the blurring of the video which changes between the frames.
