Computer for evaluating signals from nuclear magnetic resonance tomography and a nuclear resonance tomograph equipped with said computer |
摘要 |
In a computer for evaluating signals from nuclear magnetic resonance tomography and a tomograph using such a computer, the neuronal activity measured during a nuclear magnetic resonance tomographic examination follows a protocol, which reproduces the temporal sequence of stimuli. During a correlation analysis, the sensitivity of known means to changes in the signal-response form normally decreases with each activation cycle. According to the invention, better evaluation results can be achieved in the correlation analysis by using a constant number of n data values in a correlation analysis employing a sliding-window technique. As the data measurement progresses, the oldest value is continuously disposed of and the most recent data value utilized in the calculation.
