RESUMO

The technology evolution seen in the last years provided large adoption of digital image acquisition equipments, such as: X-rays, computed tomography, magnetic resonance and ultrasound. The use of these devices in daily hospital routine generates an expressive image data volume which demands intelligent solutions for image storage, distribution and visualization. Such role is played by picture archiving and communication systems - PACS - which make extensively use of the DICOM protocol, world industry standard for image transmission and codification in medicine. Due to its digital nature, recently several medical image processing applications were developed and some programs used to process mammography and chest computed tomography images became commercial products in the last five years. These applications are usually known as CAD or computer-aided diagnosis. Its known that CAD solutions may improve the diagnosis efficiency and accuracy by detecting and/or classifying automatically abnormalities and/or diseases in radiologic exams. However, little effort was done in the sense of integrating the CAD tools and picture archiving and communication systems. To really assist radiologist diagnosis CAD needs to process digital images that are usually stored in the PACS server. Nowadays, specialist image processing programs like CAD still remains being used on an isolated workstation and the processing results are not integrated in a suitable fashion to other information systems such as HIS (Hospital Information System), RIS (Radiology Information System) and PACS. The work described in this dissertation presents a CAD-PACS integration solution based on free and open source programming libraries. Its hoped that this solution may contribute in an effective manner to increase the productivity and improve the radiology workflow, bringing benefits to the whole hospital environment.
