Performance of CR and DR imaging characteristics and clinical application of comparative study

Yongdong WU

China Medical Equipment.2014;(5):30-31,32. doi:10.3969/J.ISSN.1672-8270.2014.05.011

Objective: To evaluate CR (Computer X-ray imaging system) and DR (digital X-ray imaging system) imaging performance, features, advantages and disadvantages, and for application-level comparative analysis instrumentation for clinical application of scientific and rational resource reference. Methods:In the city diethyl hospital radiology shot 852 CR and DR tablets were retrospectively analyzed, focusing on the performance evaluation of two components as affecting the quality characteristics and radiography, focusing compare their clinical applications. Results:CR imaging quality was 89.9%, DR was 94.8%, DR radiography quality is higher than the CR, the difference was statistically significant(x2=7.864, P<0.05); DR waste film was 1.4%, CR rate of waste film 9.4%, DR radiography rejection rate was significantly lower than on the CR (x2=6.541, P<0.05), the difference was statistically significant. DR at the receiver radiography kV and mA seconds on the overall value slightly lower than CR, but the difference was not statistically significant (t=0.6784, t=0.7541;P>0.05). Conclusion: CR and DR mutual advantages and disadvantages, CR flexible, and lower cost, but the DR over CR has a higher spatial resolution, wider dynamic range and lower X-ray radiation, and a low rate of waste film radiography speed, high work efficiency. Suggest playing two advantages for clinical applications to provide more choices.

Research on Volume RAD technique and dose control methods

Yun ZHOU

China Medical Equipment.2014;(5):46-47,48. doi:10.3969/J.ISSN.1672-8270.2014.05.017

Objective: Three dimensional X-ray imaging by Volume RAD, familiar with the operation method, a reasonable set of parametersin time, improve the technology efficiency at the same time, the control of possible ways to reduce the radiation dose. Methods: The 168 cases of patients with Volume RAD examination were divided into low, middle, high dose group, dose ratio was 5:10:15; respectively to examine patient’s chest, head, cervical spine, pelvis and knee joints, observe its effect. To track acquisition and scanning sampling, analyze of experiment and the effect. Results:The experimental results show, small lung nodules and trabecular bone dose, high dose group in the image quality is better than the dose than the low dose group, the display image quality, no significant difference between the 3 groups. Conclusion:After a time exposure capture can be parallel to the image surface of the detector series, was displayed in thecomplex structure and the overlapping parts of the details. But its operations are complex, need the exposure dose on dozens of times, how to control the exposure time and dose, which needs further research to select the best dose control scheme.

Research on the application of the anesthesia information system in the hospital

Yi ZHU ; Zhengxiong XU ; Wenfeng LI

China Medical Equipment.2014;(1):69-70,71. doi:10.3969/J.ISSN.1672-8270.2014.01.024

The anesthetists not only pay attention to the exploitation and application of the information resource but also rely more and more on the convenience caused by the informatization. Based on HIS, LIS, and PACS, the Anesthesia information system has been constructed in order to guarantee the quality and safety of the anesthesia. The Anesthesia information system shares the information with HIS and LIS and manages the medical information such as the surgery and anesthesia closely. The paper introduces the notion of the anesthesia information system and its main function and also the predicted effect during the management of the anesthesia information system. Meanwhile, some problem about the application has been mentioned.

Hongye ZHANG ; Kai DENG

China Medical Equipment.2014;(1):92-94,95. doi:10.3969/J.ISSN.1672-8270.2014.01.033

Objective:To analyze manifestation of spine tuberculosis in CT and MRI, compare two kinds of techniques respectively of diagnosis advantage. Methods: Retrospective analysis of 18 cases confirmed by the surgical operation and pathology imaging of CT and MRI Material of spine tuberculosis. Results: The CT can nicely show that the bone destruction, the bone increase osteoslerosis, sequester and new-born formation and narrow of intervertebral disc, swelling paraspinal soft tissue and psoas major muscle abscess, spinal canal of bone is narrow, calcification. Although CT can show intervertebral disc involvement and terminal plate of vertebral body destruction in sagittal reconstruction, not equal to MRI sensitive, Evaluating intervertebral disc involvement and area of paraspinal soft tissue swells, changed in early days spine tuberculosis of valuation, MRI had obvious advantage. Conclusion: Combining CT and MRI can reflect the image of spine tuberculosis to learn a characteristic completely and be advantageous to diagnosing and discriminate diagnosis of spinal tuberculosis.
