Accompanied with the application of CT,MRI and DSA in hospital,the digital radiography is gradually instead of the general radiography.The digital radiography system is more advantage in the field of the image collection,display,procession,management and transmission compared with the general radiography.

Objective: To design device to measure D/T index which is used for evaluation of arteriosclerosis. Methods:By calculating the detected date of blood pressure values, pulse pressure, pulse rate, pulse patterns and SpO2 on the extremities, we get a set of analytical data in the system in order to analyze the arteriosclerosis situations. Results: The device use the ECG signal as it based and modulated signal, the computer process the date of blood pressure and SpO2, then output the result by the display and printing systems. Conclusion:The device provides an effective noninvasive detection means for extremity vascular.

Objective: To achieve intelligent access to normal training or individual soldier signs information during the war, establish individual soldier health intelligent interactive regulation and health system platform of IOT, realized digitalization, information management mode. Methods: Using the communication network, intelligent call, vital signs monitoring technology, to design intelligent signs monitoring system. Results:This system is mainly for the automatic sense of individual signs in the training or war, to understand the individual activity, get the sign data, which can send information through a call or intelligent system, based on the identification and location, medical personnel to care and treatment in the shortest time, construction of intelligent information. Conclusion: Through the use of intelligent detection system to Individual life signs in training or in wartime, the system can always grasp of individual soldier signs, and realizing a complete coverage of all of the intelligent health monitoring system, to provide effective guarantee for wartime workers health.

Mobile X-ray system is a very important equipment in hospital,but it's difficult to protect the user from the exposure of the X-ray while the equipment is in use.This paper introduces a circuit that is able to control the exposure by remote controller and it can solve the problem of the protection better.The efficiency is proved to be good by experiments.

Objective: The mobile medical collaborative service platform can realize mobile nursing informatization, which will bring new changes to the nursing work, and work flow is optimized. The construction of mobile nursing system is the trend of development in informatization, in order to better service to patients, realize full nursing work informatization. Methods: Based on wireless dynamic environment, and three subsystems including nursing collaboration portal, intelligent mobile terminal application system, the message engine service system, it adopts hierarchical architecture design, based on SOA structure mode, whose modules are loosely coupled, and platform core includes: the message engine subsystem, the medical task analysis engine subsystem, WEB middleware subsystem and the client subsystem,in order to realize the service management of mobile medical collaboration. Results: According to the actual situation of nursing work in hospitals, construction of mobile nursing system by the stage of application, to meet the core work of nursing, and then realize the basic nursing work, the construction of digital implementation of nursing information, to realize the informatization construction of digital care. Conclusion: Application of the system to achieve the whole informatization of the nursing management, through access to health services, cloud services center, to share resources, to achieve full coverage of all aspects of smart care management for people's health to provide effective protection.
