Combining Adaptive Segmentation Approach for Improving Multi-resolution Image Registration on X-ray Mammograms Acquired Using Fischer’s Fused Full Field Digital Mammography and Ultrasound System (ffdmus)

چکیده
Mammogram registration can help avoid biopsies and help follow-up analysis. Mammogram registration is a challenge because of the compressibility of the breast tissue. We used the CIRS breast phantom image to study the registration methodology. The phantom images were acquired in Fused Full Field Digital Mammogram and Ultrasound (FFDMUS) framework. The acquired images were registered using our proposed three-stage registration system. The registration results were measured and evaluated, and the comparison was made for the registration procedure with and without mask operation. It is demonstrated that the mask operation can help improve the performance of the intensity based registration. The mean error from the polyline distance measurement is improved by 19.6%, and the standard deviation of the error is improved by 13.7%.

License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...
متن کاملTechnique to obtain positron emission mammography images in registration with x-ray mammograms.
X-ray mammograms reveal abnormal tissue densities, while metabolic images identify regions of abnormal metabolism. Conventional nuclear medicine and radiologic breast images must be acquired at different times with different patient positions making coregistration difficult. Accurate coregistration of metabolic and x-ray images of the breast is likely to be important when acquiring information ...

Breast cancer is one of the most frequently diagnosed cancers among women. Several techniques have been developed to help in the early detection of breast cancer such as conventional and digital x-ray mammography, positron and single-photon emission mammography, etc. A key advantage in digital mammography is that images can be manipulated as simple computer image files. Thus non-dedicated comme...
