Architectural changes with Tianyi cloud storage of China Telecom were made to the up/ down loading of the image-text mega data created in the picture archiving and communication systems (PACS)of the hospital.Thanks to the changes, the data volume uploaded by the PACS of the hospital reached 160G per day, with average upload speed up to 5.3M/second;supporting online query of all image-text data of patients.The authors hold cloud storage technology as safe and reliable, and such other merits as supporting data encryption, automatic offsite redundancy, almost online real-time read/write access,almost infinite extendibility, fast self-healing and off-site disaster-tolerant backup.

Integrando ferramentas de auxílio ao diagnóstico no sistema de arquivamento e comunicação de imagens / Integrating computer-aided diagnosis tools into the picture archiving and communication system

OBJETIVO: Este artigo apresenta um modelo de integração de algoritmos de diagnóstico auxiliado por computador dentro do fluxo de trabalho dos sistemas de gerenciamento de imagens, desenvolvido com base em um conjunto de ferramentas computacionais de código aberto e uso livre chamado dcm4che2. MATERIAIS E MÉTODOS: O modelo de integração é composto por um servidor de processamento de imagens e por serviços de comunicação. O gerenciamento de dados segue o fluxo de trabalho definido pelo perfil de pós-processamento (PWF) do Integrating the Healthcare Enterprise (IHE) e utiliza a funcionalidade de captura secundária do DICOM. Uma aplicação para lesões difusas de pulmão foi utilizada para prova de conceito. RESULTADOS: O algoritmo de classificação de padrões apresentou acurácia de 78 por cento, com base em um método de teste de validação cruzada. A integração possibilita a visualização das imagens processadas como uma nova série dentro do estudo original. CONCLUSÃO: O modelo de integração proposto baseiase em perfis do IHE e permite o estabelecimento de procedimentos padronizados. Os princípios utilizados para integração do fluxo de trabalho são aplicáveis para qualquer tarefa não interativa de pós-processamento de imagens.

OBJECTIVE: This paper presents a model for integration of computer-aided diagnosis algorithms into the picture archiving and communication systems workflow that has been developed on the basis of the dcm4che2 open source toolkit. MATERIALS AND METHODS: The proposed integration model consists of an image processing server and communication services. The data management follows the workflow defined by the post-processing workflow profile (PWF) developed by Integrating the Healthcare Enterprise (IHE) and utilizes the DICOM secondary capture functionality. An application for diffuse lung disease has been utilized as proof of concept. RESULTS: Based on a cross validation method, the standard classification algorithm presented 78 percent accuracy. The integration enables the visualization of processed images as a new series in the original study. CONCLUSION: The proposed integration model is based on IHE profiles and allows the establishment of standardized procedures. The principles used to integrate the workflow are applicable to any non-interactive post-processing task.

Application of the Extended Technology Acceptance Model to Picture Archiving and Communication Systems in Dental Hospitals / 대한의료정보학회지

OBJECTIVE: With the rapid growth of picture archiving and communication systems (PACS) in the healthcare industry, this article describes the users' satisfaction with PACS by employing functional PACS features and the two concepts of perceived ease-of-use (PEOU) and perceived usefulness (PU), based on the extended technology acceptance model (TAM). METHODS: A cross-sectional survey was conducted with dentists in 25 dental hospitals which were cluster sampled from the national registry of 132 dental hospitals. Of the 204 respondents (response rate 81.6%), the data of 159 PACS users were analyzed using the structural equation modeling method. RESULTS: The fitted model showed significant relations between the technical components and the TAM variables, via the following three significant paths: hardware to PEOU, and software to PEOU and also to PU. Moreover, the critical path of TAM variables was observed: PEOU-->PU-->SAT. Therefore, the model produced three significant routes: hardware-->PEOU-->PU-->SAT, software-->PU-->SAT, and software-->PEOU-->PU-->SAT. CONCLUSION: Contrary to expectations, the direct effect of PEOU on user satisfaction was not significant. The final model provided critical paths from technical components to user satisfaction, by utilizing PEOU and PU as intermediary, latent factors.

Current status and installation standard of dental PACS / 대한구강악안면방사선학회지

PURPOSE: Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. MATERIALS AND METHODS: Materials and methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. RESULTS: By September 30, 2004, full PACS implementations in their facilities were 88.1% in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 110 hospitals) Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. CONCLUSIONS: Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.
