DIGITAL IMAGE STORAGE 总被引:2,自引:2,他引:0
SETH WALLACK 《Veterinary radiology & ultrasound》2008,49(S1):S37-S41
Digital image archival requires less physical storage space, allows for rapid storage and retrieval and avoids loss in image quality over time or with image duplication compared with film storage. Because medical imaging data are critically important and, by law, must be stored in a safe, accessible manner, it is imperative not to have one computer error destroy all copies of the image data. Several options for image storage media are available including magnetic tape, optical media, spinning disks and solid state. Other considerations include on-site vs. off-site storage, redundancy, on-line vs. off-line storage, and removable storage media for disaster recovery. The different storage media can be used in different configurations to provide sufficient protection of digital data. Choose a storage system that will keep your data safe from unauthorized access, hardware failure, and clinic disasters. 相似文献

Objective To estimate the changes in productivity and profitability in a group of wool-growing farms as they adopted major recommendations from agricultural and veterinary studies.
Farms Four wool-growing farms in south western Victoria were selected from the clients of the Mackinnon Project, a farm consultancy service run from the University of Melbourne. Each farm had closely followed recommended procedures, kept comprehensive financial and physical records and had been clients for at least 5 years. The comparison group was the South Western Victoria Monitor Farm Project (SWVMFP), about 45 farms in the same region as the study farms that were monitored annually by Agriculture Victoria.
Procedure For a 7-year period, the financial and physical performance of both groups of farms was estimated. Stocking rate, wool production, gross farm income, farm operating costs, net farm income and return on assets were compared.
Results Mean gross farm income of the four study farms steadily rose from 86% of the average SWVMFP farm before the adoption of recommendations to an average of 155%. During the same period, net farm income rose from 70% to 207% of the average of the SWVMFP. Return on asset of the four farms rose irregularly from 26% to 145% of the average of the SWVMFP. Farm operating costs on the four farms were higher than for the SWVMFP group, but the ratio of costs remained relatively constant.
Conclusion The adoption of proven research results was associated with large increases in net farm income. An increase in gross income, rather than a reduction in costs was the main reason for this. Research results offer a way to increase the financial viability of wool-growing farmers, many of whom are currently unable to maintain their lifestyle, resources and infrastructure. 相似文献

APPLICATION OF THE PIN-HOLE COLLIMATOR IN SMALL ANIMAL NUCLEAR SCINTIGRAPHY: A REVIEW 总被引:1,自引:0,他引:1
Karen Young BS Gfregotry B. Daniel DVM MS Anne Bahr DVM 《Veterinary radiology & ultrasound》1997,38(2):83-93
The pin-hole collimator is used to improve spatial resolution and magnify areas of interest. The pin-hole collimator has many applications in small animal veterinary scintigraphy. The principles of image formation for the pin-hole and parallel hole collimators are reviewed. The effects of distance on resolution and sensitivity are presented for the pin-hole and parallel hole collimators. Specific application of the pin-hole and parallel hole collimators. Specific application of the pin-hole collimator in veternary scintigraphy are discussed. 相似文献

天祝县莫客片一带牛梨形虫病发病率达24.6%,病死率28.6%;羊发病率34.2%,病死率27.5%,与往年相比变化不大,笔者从蜱控制、梨形虫病预防加治疗相结合综合防控入手,作控制、预防药物试验对比,筛选药效长、低毒、安全、广谱药物,结果显示用敌杀死环境灭蜱,同时注施可诺注射液控制蜱感染,用蒿甲醚注射液或盐酸咪唑苯脲,预防和治疗梨形虫病,能有效降低当地牛羊梨形虫病的发病率和病死率。 相似文献
