“…Therefore, once a digital image of the chest is captured, it can be processed directly by the computer. 3 The digital imaging PACS is a combination of hardware and software hybrid system that is used to acquire, store, deploy and retrieve medical images using Digital Imaging and Communications in Medicine (DICOM) standard. The images and reports are transmitted digitally via PACS by integrating the system with the radiology information system (RIS) and hospital information system (HIS).…”

The purpose of this article was to represent the first experience of applying a picture archiving and communication system (PACS) at the Universiti Putra Malaysia with the cooperation of Universiti Teknologi MARA hospital, and to analyze the applicability of PACS, its impact on health care, its benefits to medical employees, and propose a prototype application of PACS. Methods: The main PACS components were discussed, HL7 and DICOM standards were introduced, and a prototype of WebXA application was proposed. Results: The results of WebXA revealed the ability of this application to retrieve, store, and display angiography images on a web browser anywhere, as long as an Internet connection is provided. Conclusion: This article presented PACS with its components and standards, a prototype application was discussed and evaluated, and a few recommendations have been provided for more improvements in the future.

Abstract.A computerized pulmonary segmentation based on the detection of oriented edges was performed in postero-anterior (PA) digital radiography (DR) images. To further improve detection of lung contours, a method based on the use of active contours models was developed. First, the technique calculates a set of reference lines to determine the relative position of the lungs in the image. Then, vertical and horizontal rectangular regions of interest (ROIs) are studied to identify the preliminary edge. These points are an approximation to the lung edges that are adjusted using the active contours models. We studied the influence of the different parameters of the active contours on the final result over 30 DR images. Results prove that the active contour models, with selected parameters, can be used to improve the results of a given segmentation scheme.

“…The fact is that in many countries, such as Spain, whose technological or scientific-technical system is traditionally weak, the focus has never been on the transfer to the industry of research and innovation developed in the universities. In fact, that would be one of the endemic ills of our University, its true Achilles heel, the lack of relationship with the industry [1].…”
