RESUMO
The intelligent level of the modern medical equipments is higher than before and the automatic calibration circuits are largely used. The control circuit of the intelligent equipments is quite complicated and its working modes have been simplified to four-terminal or double terminal nets. The intelligent medical equipments such as CT, MRI, DR, PET/ CT have more chances to have some "soft" errors that are usually related to the zero-line calibration. In actual use, it can be noticed and performed, and the detecting and servicing for the medical equipments can be much easier than before.
RESUMO
The quality of technicians is the dominate factor to determine the level of medical engineering section.The key to improving technical skills is to do basic jobs.During the Tenth Five-Year-Plan,we not only did many basic jobs and research works in science but did a lot of revolutions in order to accelerate the development of medical engineering and improve the working quality.Compared with the past,we have made great progress and development in standardized management,technology support,technician education,scientific researches,studies,technology level,the quality of service,etc.
RESUMO

RESUMO
This paper introduces the method of electron tomography three-dimensional reconstruction,which is widely applied in structural biology field and summarizes its advantages and disadvantages.The aim is to provide a reference for the application of the method.
RESUMO
The two important methods for displaying three-dimensional data called surface rendering and volume rendering are introduced and analyzed.It is concluded that volume rendering is superior to surface rendering for the former one provides a basis for visualization of three-dimensional data.
RESUMO
The purpose of this paper is to develop a new dynamic image analyzing technique with the ability of real time measurement on red blood cell membrane minute fluctuation based on super resolution.The technique is proved strictly by correct theory,also its software realization as well as its advantage and disadvantage are also involved in.The results of applying the method in Aspergillus flavus cell(AFC)and red cell have proved its availability and achieved some new findings.
RESUMO
Cranio-maxillofacial computer aided system is discussed including its conception,study situation,design sig-nificance and system structure,and then the main problems and its solution project of the research is also expounded.The clinical application of the system can be treated craniofacial deformities perfectly,producing very good social and economic benefits.
RESUMO
Objective To develop ECG Holter system with SD card as storage medium. Methods Data that used MSP430F449 SCM to acquire 3-channel ECG signal to record SD card through serial peripheral interface were reviewed and analyzed on computer. Results Portable ECG Holter System based on SD card is realized. The using of SD card can enhance storage performance. Conclusion Low-cost, and high-performance solution program is observed.
RESUMO
The quality control methods are the important to improve the exactness of diagnses and the effectivity of treatment.X-ray imaging quality is an important factor in improving the X-ray diagnosis effect.To serve this purpose,medical engineering personnel should do the X-ray quality control regularly to keep every parameter in accordance with national standards and demands.The quality control methods for several important indexes of X-ray generators are also discussed.[Chinese Medical Equipment Journal,2008,29(2):99-101]
RESUMO
Ambulance is a kind of new medical technique vehicle along with the development of medical science.Many countries are developing new ambulances in order to satisfy the demand of the emergency highway accident rescue.The GPS communication system and the vehicular medical power design are the most important parts of the ambulances for their complicated technology.This article discusses these two problems.
