Improvement of an automated patient recognition method for chest radiographs using edge-enhanced images by Sobel filter

摘要

To utilize a large number of digital images in picture archiving and communication system (PACS) environment. it is important that all of images are stored in correct locations such as in the proper patients' folders. However, if patient information, such as the identification number or the patient name has been entered incorrectly, the image will be stored in the wrong patient's folder. We are developing an automated patient recognition method for chest radiographs based on a template-matching technique to prevent such filing errors. In this study, we employed edge-enhanced images by Sobel filter to improve the performance of the patient recognition based on a template-matching technique.
