An image-based technique for correction of the posture of patients during the acquisition of thermographic images
Keywords:
Posture, thermal imaging, ROI extractionAbstract
Aims: This paper presents a technique developed to assist in the thermal imaging breast procedure in the Capture T2 position modified for diagnosis of breast cancer. Materials and Methods: In the development of the technique we rely on acquired 49 thermography capture T2 database Universidade Federal Fluminense position. Of these 32 were captured using static protocol capture and ventilation with 17 dynamic and alcohol. Results: To validate the results we use a software segmentation breast UFF developed by considering how correct posture when you can extract the ROI. In 42 images (85.71%) got similar results between the two approaches are different in only 7 images (14.29%). Conclusion: The technique proved to be robust in check, correction of the posture of patients who are submitted to thermography exams, enabling the correct posture from a better imaging of the breast structures that are useful for more accurate medical diagnoses, and auxiliary methods of computer-aided diagnosis.
