Gender imbalance in medical imaging datasets produces biased classifiers for computer-aided diagnosis
(National Academy of Sciences, 2020-06)
Artificial intelligence (AI) systems for computer-aided diagnosis and image-based screening are being adopted worldwide by medical institutions. In such a context, generating fair and unbiased classifiers becomes of paramount ...
Learning deformable registration of medical images with anatomical constraints
(Pergamon-Elsevier Science Ltd, 2020-04)
Deformable image registration is a fundamental problem in the field of medical image analysis. During the last years, we have witnessed the advent of deep learning-based image registration methods which achieve state-of-the-art ...
Compensatory fuzzy mathematical morphology
(Springer London Ltd, 2017-09)
In this paper, we propose the use of compensatory fuzzy logic to extend mathematical morphology (MM) operators to gray-level images, in a similar way than fuzzy logic is used, naming it compensatory fuzzy mathematical ...
Improved particle swarm optimization algorithm applied to rigid registration in medical images
(Springer Verlag Berlín, 2017-04)
Image registration is a space-temporary correlation process that allows comparison and/or image matching. This process has value into medical area when it comes to compare images acquired by different modalities or in ...
Surface characterization of reprocessed single-use medical catheters by fractal mass dimension
(World Scientific, 2004-03)
Reprocessing of single-use medical devices is an issue of concern and discussion due to infection risk and operation failure. Cleaning procedures and sterilization processes can produce structural changes and relevant ...
Synthetic aperture ultrasound imaging using GPUs
(Institute of Electrical and Electronics Engineers Inc., 2017-01)
Ultrasound images are widely used for medical diagnosis and for Non-Destructive Testing (NDT) in the industry. Among alternative imaging methods there are the Phased Array techniques, which allow processing ultrasound ...
Artemisia: Validation of a deep learning model for automatic breast density categorization
(AME Publishing Company, 2021-06)
Background: The aim of this study is to validate a deep learning model for the classification of breast density according to American College of Radiology’s breast density patterns. Methods: A convolutional neural network ...
Multi-scale fidelity measure for image fusion quality assessment
(Elsevier Science, 2019-10)
Image fusion is considered an effective enhancing methodology widely included in high-quality imaging systems. Nevertheless, like other enhancing techniques, output quality assessment is made within small sample subjective ...
Tracking Targeted Bimodal Nanovaccines: Immune Responses and Routing in Cells, Tissue, and Whole Organism
(American Chemical Society, 2014)
Water-equivalence of gel dosimeters for radiology medical imaging
(Pergamon-Elsevier Science Ltd, 2018-11)
International dosimetry protocols are based on determinations of absorbed dose to water. Ideally, the phantom material should be water equivalent; that is, it should have the same absorption and scatter properties as water. ...
