Multi-modality medical image fusion technology has become an important development along with the advancement of image equipments and various medical imaging modes,and has been used in diagnoses and therapy gradually.In this paper,the familiar CT-MRI images are fused by different arithmetic,and the result sare analyzed.

We got vary data about neuron-threshold from animal experiment. We try to find the disciplinarian from the data in order to confirm something. In this article we first confirmed unitary method of neuron-threshold; and then found t he complication working on the neuron-threshold parameter and the connection bet ween one another; at last proved the non-linear characteristic about neuron. The se conclusions do well to the clinic application of nerve electro-physiology; ne rve biology and neuron-threshold. Along with the experiment data enriched and co nsummated more and more, using analysis method for experiment, neuron-threshold will be up to par of clinic diagnosis and treatment.

This paper mainly introduces the design for system of evoked potentials detecting based on technology of mobile computing platform and CF interface. The CF+ card in IO mode based on the mobile computing equipments and its CF interface are designed, and the driver and application software on Windows CE platform are also written at the same time. The system with these hardware and software can perform the task of generating evoked signals and sampling evoked potentials signals. Simple hardware design and perfect software support are available in this system, which can meet the research needs in many fields of evoked potentials signals.
