车载X线机数字化系统的研制

目的:对现有的车载式X线机进行数字化升级,提高车载X线检查系统的伤病员通过能力。方法:对现有数字化摄影技术进行分析,对3种平板探测器进行比较,选择CXDI X线平板探测器系统对车载X线机进行数字化升级。结果:实现了X线信号实时同步,并可在工作站对数字化图像进行剪裁、标注检查信息等编辑工作。结论:提高了装备的工作效率,增强了部队保障能力。     

改装数字化X线机DR摄影及应用

目的：DR数字化分辨率高，它是采用平板探测器为传统X线带来了前所未有的高分辨率影像。方法：采用CANONDR系统，操作台简单，屏幕上各个投照部位显示清楚，对屏幕上显示图像可重新修改和删除，对不理想图像可做频率调整．如对屏幕上显示多幅图像可进行重新预览，窗宽、窗住重新调整和重新发送，屏幕上显示投照部位任意翻转和剪切，只要是大型进口X线机就可以改装，大大节约了经费。结果：DR照片质量大大优于胶片质量，由原来用胶片甲片率的78％提高到用DR数字化甲片率的99．5％，避免乙片率和废片率。结论：DR动态范围宽，摄影的宽容度大，无失败摄影，用DR诊断信息丰富。     

GE数字化X线机影像系统不曝光故障检修

故障现象 bucky上电grid led闪烁不定，droc开机后报错：“the bucky is in error state for long time，the arry has been powered down(bucky待机时间过长，电源自动切断)”。DR无法正常曝光。

How to develop breakthrough physician-to-physician relationships

In today's highly competitive marketplace, specialty practices must strive to distinguish themselves from the competition. One key strategy is to provide exceptional levels of service based on fundamentals already in play among many non-healthcare service providers. The problem is that too many practices are failing to deliver. This article outlines precautionary principles that will enable specialty practices, and even hospitals, to develop stronger, more positive physician relationships that increase loyalty and keep your patient pipeline filled.     

How to develop a business case for quality.

OBJECTIVE: To describe the steps in developing a business case for quality-enhancing interventions (QEIs) in health care. ANALYSIS: The development of a business case for QEIs in health care involves 11 steps. These steps include (1) describing the intervention, (2) determining perspective, (3) identifying the effects of the intervention on quality, (4) designing the study, (5) identifying and measuring cash flows, (6) considering the effects of capacity constraints, (7) selecting a measure of return on investment, (8) determining the time horizon for the analysis, (9) determining the discount rate, (10) adjusting costs and savings for inflation, and (11) determining organizational readiness for business case development. A checklist offers guidance on assessing readiness for the business case. CONCLUSION: The absence of a 'business case' for quality is frequently cited as the reason health care organizations do not implement QEIs, despite decades of careful research demonstrating their effectiveness. Our continuing commitment to advancing the discipline of business case analysis is based on a belief that delineating the cost and economic implications of investments in QEIs is a critical threshold issue to widespread adoption of evidence-based quality improvements. We believe it is appropriate and timely to consider how best to standardize approaches and move the field of business case analysis forward.

How to motivate physicians and develop a physician champion

Physician champions and leaders are essential to the success ofa CCIS implementation. Physician champions or leaders can be developed by recognizing the qualities of a leader and cultivating them. Finally, sustainable second-order change is facilitated bv a transformational leader--a leader who is charismatic, considers individual characteristics and needs of the constituency, and stimulates the constituency intellectually. A transformational leader does not accept the status quo but rather is continually questioning and offering constructive problem solutions. Transformational leadership may require more patience, time, tolerance, and resources, but it is worth the effort.
