ABSTRACT
Objective To improve the quality of medical image and enhance the image in range of frequency area.Methods Images were enhanced by adopting the arithmetic of Laplacian and Sobel,and using image multiplication and addition.The effects were compared.Results After being transformed in Laplacian,the interior frame of original image turned to be obvious and the original image was led into much noise simultaneously.In comparison with the former one,the image would be more smooth after being transformed by Sobel.Treated by average filter,the influence of noise and tiny detail would be reduced.Conclusion The toolbox of Matlab can simplify the program work,which provides a method for medical image processing.
ABSTRACT
Objective To introduce operating principle and temperature control way of STA COMPACT. Methods The temperature control signal of STA COMPACT coagulometer are analyzed and recorded. Results By regulating the power supply time of the voltage to adjust temperature. Conclusion Based on the principle of temperature control to determine temperature fault that has helping role.
ABSTRACT
Objective To develop a software to turn the management of combat readiness into information -based management in computer. Methods Based on the Platform of Pb10.0, management modules were designed and database was developed. Results In the corresponding module, operations such as modifying, inquiry or increase could be performed. Conclusion The management level is raised, the waste of commodity is reduced and the equipment in good condition is ensured.
ABSTRACT
Objective To discuss the possibility of application of embedded system to medical equipment. Methods The principle and actuality of embedded system were explained, and a concrete example was presented. Results The application of the embedded system to medical equipment reduced the cost of medical equipment, and increased the realtime capability, reliability and longevity of medical equipment. Conclusion More and more embedded systems are being applied to medical equipment. Medical equipment based on embedded system have been developed ceaselessly.
ABSTRACT
Objective To develop a set of software to manage war readiness material, such as the medical equipment, the medical material of medicine(consumables), the instrument, etc. Methods Based on the platform of PowerBuilder, management modules for equipment, consumables, medicine and others material were designed. Results Material data could be modified, added, reduced and queried in the corresponding module. Conclusion Changing the mode of manual management, the management level is raised, the waste is reduced and equipment can be repaired promptly.
ABSTRACT
Scientific management of medical equipments in army hospitals makes the equipments ready for military medical service support during new military revolution, in which such aspects get involved in as regulation-based application, installation, utilization, maintenance and scrapping, feasible demonstration, reasonable lectotype, purchase through Internet.
ABSTRACT
The faults of large-scale equipments of hospitals, such as imaging equipment, laboratory equipment, sterilizing equipment and bioelectric equipment, result in considerable expenses of hospitals. Usual and special preventive maintenances (PM) should be performed to decrease the expenses. Additionally, PM can be carried out when the condition is possible.
