| Descripción |
We propose a new filtering/estimation method
for nuclear medicine imaging. The statistical method of crossvalidation
is used to design optimal wavelet domain filters for
improved image estimation. The quality of the resulting images
is much better than standard image estimates, in both
visual and mean square error senses. Moreover, experiments
have shown that, using the new estimate, we can reduce the
acquisition time by a factor of two and still retain high image
quality.
I. Introduction
This paper reports on the development of a new waveletbased
filtering algorithm for nuclear medicine imaging.
Wavelet-based filtering is a relatively recent advance in digital
signal processing (DSP) [1]. Wavelet-based filtering offers significant
theoretical advantages over classical linear filters [1, 4],
and real-world applications have demonstrated the outstanding
performance of these new methods [3].
The basic DSP problem in nuclear medicine imaging is to
design a digital filter that that recov...
