Inventor: SHIMIZU YOSHINORI
IPC: A61B6/00
Filed: 2003-01-07
Abstract: <P>PROBLEM TO BE SOLVED: To support the insertion of a catheter, etc., by displaying the traveling direction of a blood vessel at an arbitrary position designated by an operator on an X-ray fluoroscopic image in performing IVR.  <P>SOLUTION: The traveling direction of the blood vessel is analyzed based on a three-dimensional image or a rotary DSA image. In result, a guide mark for indicating the traveling direction of the blood vessel at the position designated by the operator is displayed by superimposition on the X-ray fluoroscopic image under collection. Thus, a medical implement such as the catheter is smoothly inserted into the desired blood vessel along the guide mark displayed on the fluoroscopic image. Besides, the direction for advancing the medical implement is easily recognized, the operator easily performs procedures, and, then, a time for the procedures is shortened.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Weighted credit-based arbitration using credit history
Inventor: HONG XU
IPC: H04L47/52
Filed: 2003-01-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system and a method for managing data transmission, by using a regular credit count and a history credit count for each of many queues.  <P>SOLUTION: When data is transmitted from a queue, a count is decreased, and the count is increased at given intervals in the case that the queue doesn't face backpressure which blocks transmission. When transmission from the queue is blocked, the history credit count is increased instead of the regular credit count. Consequently, the history credit count traces potential transmission opportunities which may be lost due to blocking of transmission from the queue. The history credit count is periodically polled instead of the regular credit count to give each queue an opportunity to catch up in its use of opportunities for transmission.  <P>COPYRIGHT: (C)2003,JPO
