[The research on a pocket microcontroller system for target controlled infusion].
This paper present a microcontroller system for target controlled infusion according to pharmacodynamic parameters of intravenous anesthetics. It can control the depth of anesthesia by adjusting the level of plasma concentrations. The system has the advantages of high precision, extended function and easy operation. It has been now used in the clinical anesthesia.

[Lossless ECG compression algorithm with anti- electromagnetic interference].
Based on the study of ECG signal features, a new lossless ECG compression algorithm is put forward here. We apply second-order difference operation with anti- electromagnetic interference to original ECG signals and then, compress the result by the escape-based coding model. In spite of serious 50Hz-interference, the algorithm is still capable of obtaining a high compression ratio.

[CT/PET image registration based on a region similarity measure].
In this paper, CT/PET multimodality medical image registration is performed by a region similarity measure (RSM), accompanied with an improved segment method and Powell optimization algorithm. RSM has been proved to be a quick, accurate and robust algorithm by the experimental results.
