Automated ventricular systems segmentation in brain CT images by combining low-level segmentation and high-level template matching
2009
BMC Medical Informatics and Decision Making
Preserved Fulltext
The segmentation of ventricles provides quantitative measures on the changes of ventricles in the brain that form vital diagnosis information. ...
Automatic processing of these CT brain scans could speed up the decision making process, lower the cost of healthcare, and reduce the chance of human error. ...
Acknowledgements The authors would like to thank Carolinas Healthcare System (CHS) for providing the CT brain dataset. ...
