MULTI-MEASUREMENT NOISE REDUCING SYSTEM |
摘要 |
In a multiple-measurement system, a weighted sum of the measurements is used to provide a selective image. An additional weighted sum is used to provide an increased signal-to-noise ratio of some desired parameter of the image. The high frequency components of the increased signal-to-noise ratio image are combined with the low frequency components of the selective image to provide a selective image with improved signal-to-noise ratio. The combining operation can utilize the ratios of the derivatives in each signal to provide the correct amount of high frequency signal at each transition. |
