Objective To solve the encountered problem of lack of space and dyskinesia of detector in dual energy X-ray absorptiometry system, Methods The method used PartitionMagic8.0 software to partition space in hard disk and added the load to keep the detector balance for moving, Results The original software can run in hard disk, and the pulleys are not gotten force from side. Conclusion The reason of problem is analyzed to find the method that can reduce the percentage for system failure and improve precision and accuracy of data.

Objective To discuss the medical consumable materials and its storeroom management techniques. Methods From techniques view, it was thoroughly discussed the concrete operating regulations of applying, check in, check out, storeroom specific management, data statistics and second-level storeroom of consumable materials. Results It basically included all contents of management of consumable materials, It has important directive function for medical consumable materials informational management and department of equipment management. Conclusion Economic benefit and socialeffect can be more exerted through the usage of management techniques of medical consumable materials, and more full-scale service can be provided.

Relative problems in the management of HIV antibody primary screening lab are discussed, including laborato-ry building, staffing and training, equipment management, document management, reagent management, quality control and security protection. It is pointed out that the standardized laboratory management is an important part of the HIV antibody primary screening lab's quality Control.

Medical equipment maintenance management as an important part of hospital management has always been a difficulty, particularly in small and medium-sized hospital. Because of their weak technical force and the growing diversity, complexity, high-tech modern medical equipment, methods for scientific and effective management are more important. The experiences of how to manage equipment maintenance are introduced.

Obiective To discuss the diagnosis value, limitations and mutual complement of MRI and TDUI in the fetus. Methods, TDUI and MRI was performed in 24 cases pregnant women that suspected fetus congenital malformation by Ultrasound examination, the examination results were compared by MR1 and TDUI with the clinical results.Results The 9 cases congenital malformation of 24 cases pregnant women were found by MRI. The 9 cases were confirmed and 3 cases were more sufficient by MRI. The one case examined by MRI was normal other than Ultrasound examination. Conclusion MRI is superior to Ultrasound in diagnosing malformation of nervous system. The Ultrasound and the TDUI in particular is better in finding the surface malformation than MRI. In clinical application, MRI and Ultrasound must be connected to make up the limitation and have a definite diagnosis.

Obiective To study the regularity of three-dimensional displacement in respiration of lung cancer. Methods Af-ter CT scanning, the CT images were transferred into target planning system (TPS) to obtain three-dimensional reconstruc-tion images. Then target drawing and noting of target position, tumor volume, lung function, patient gender, age and weight were performed. The images during the course of inspiration and expiration in simulator were scanned and transferred into TPS by DICOM RT port. At last, the three-dimensional displacement curve of the interested points(X,Y and Z axis) could be obtained. Results The three-dimensional real time displacement curve of lung cancer interested points could be estab-fished by the way of collecting simulator images and drawing interested points. The maximum displacement range of the interested points were 4.2mm in Z-axis(head-foot direction), 3.8ram in X-axis(left-right direction), 2.9ram in Y-axis(ante-rior-posterior direction). Conclusion The three--dimensional real time displacement curve of lung cancer at any point of the target can be established by collecting the dynamic images in simulator and reconstructing of the corresponding images in target planning system through the DICOM RT.

The question about interference in the use of medical equipment affects patient's diagnosis and treatment. Through analyzing the common interference problem, the related solutions are put forward.

The development history, the features and laws of guaranteeing medical supplies under emergency situation are introduced briefly. The allocation of resources, the key factors in management and the technique supply are described. By looking at the trend and the future work on how to guarantee medical supplies in the state of emergency, some conclusions can be made: guaranteeing medieal supplies in the state of emergency is a whole new field. Only when the experience is accumulated, and when the eoneepts and techniques from foreign countries are learned, the supplies for clinical and first aid to be delivered safely and in time can be guaranteed. Thus, the number of lives saved will be maximized.

The characteristics of C8051F340 MCU and USB communication, and the design method of system's hardware and software structure are introduced briefly. The whole system is proved stable and reliable by experiment. The Universal Serial Bus (USB) communication technology has great value in course of system design and study.

Medical treatment team plays an important role in improving our logistic support ability. A new idea of how to digitalize medical treatment team together with the foreground and difficulties towards medical treatment digitization is expected under the reality of team information construction and the after thinking about its new construction mode.
