Abstract: A system and method for generating CT-type three dimensional imaging information from a conventional C-arm fluoroscope system. This enables the adaptation of widely used C-arm installations to provide CT-type information. The system uses a three dimensional target disposing in a fixed position relative to the subject, and obtains a sequence of video images of a region of interest of a subject while the C-arm is moved manually or by a scanning motor. Images from the video sequence are analyzed to determine the pose of the C-arm relative to the subject by analysis of the image patterns of the target. Images are selected from the video sequence according to predetermined criteria. A set of two-dimensional image data with associated positional data is obtained, which is used to reconstruct a three dimensional volumetric set of imaging data of the region of interest of the subject.

Title: Method for compensation of ofdm signal having cfo and dco, program, recording medium, and receiver
Inventor: LIN HAI
IPC: H04J11/00
Filed: 2008-06-19
Abstract: In a signal of the OFDM method, a frequency offset (CFO) and a DC component offset (DCO) are generated. In order to correct them, there is suggested a method for compensation by mixing a pilot signal in a communication signal. However, if the pilot signal period is long, it is necessary to use a compensation method using no pilot signal for the signal compensation during the period. However, there has been no method for compensating both of the CFO and the DCO without using any pilot signal. By using the orthogonal feature of the OFDM signal, a matrix of the system where the CDO and the DCO are generated is subjected to a singular value decomposition so as to obtain in advance a numeric value string of a CFO candidate value and a CFO check data capable of demodulating a zero from a reception signal, so that a compensation unit (17) successively multiplies the reception signal by the numeric values. The CFO representative value when the smallest value is demodulated is outputted as an estimated value for compensation.
