[A medical image fusion method based on fuzzy mathematics].
In this paper, a method based on fuzzy mathematics to fuse multimodality medical images was presented. The improved FCM algorithm was adopted to segment images, and automatic fuzzy redistribution algorithm to define the subject degree. 16 different combinations of image tissues and 16 context relations, 256 models altogether, were considered. The result showed that the method had the great ability of anti-error and anti-segmentation interference and had the characteristics of robustness, quickness, and accuracy.

[Numerical simulation of the relationship between blood pressure and blood stream of arteries].
The quantitative relationship between blood pressure and blood stream of arteries, which is delineated by hemodynamics, is rather complex to understand and analyze mathematically. An equivalent simulated mathematical model was utilized to numerically describe this sort of relationship. ⋯ Some important conclusions about quantitative relationship of the layered flowage were drawn through the simulation results. The research results presented in this paper have important reference value in respect of quantitative research of circulation physiology and clinical diagnosis and analysis of some illness within circulation system.

[Study on technique of thermal imaging and soft-sensing].
The differences of body surface temperature reflect the changes of the status of body tissues. In this regard, detecting and forecasting the changes of the surface temperature is the objective of the technique of medical thermal diagnosis, and how to diagnose the disease earlier with the use of thermal images is a common problem in the field of medical diagnostics and biological engineering. The authors put forward that utilizing the soft-sensing techniques in the field of engineering will be a good solution.
