Medical imaging has become an absolutely essential diagnostic tool for clinical practices; at present, pathologies can be detected with an earliness never before known. Its use has not only been relegated to the field of radiology but also, increasingly, to computer-based imaging processes prior to surgery. Motion analysis, in particular, plays an important role in analyzing activities or behaviors of live objects in medicine. This short paper presents several low-cost hardware implementation approaches for the new generation of tablets and/or smartphones for estimating motion compensation and segmentation in medical images. These systems have been optimized for breast cancer diagnosis using magnetic resonance imaging technology with several advantages over traditional X-ray mammography, for example, obtaining patient information during a short period. This paper also addresses the challenge of offering a medical tool that runs on widespread portable devices, both on tablets and/or smartphones to aid in patient diagnostics. 2023-06-20T11:11:04Z 2023-06-20T11:11:04Z 2008-07 journal article 0305-1048 10.1093/nar/gkn335 https://hdl.handle.net/20.500.14352/51805 http://dx.doi.org/10.1093/nar/gkn335 http://nar.oxfordjournals.org/ eng BIO2007-67150-C03-02 S-Gen-0166/2006 CYTED-505 PI0058 CSD00C-07-20811 TIN2005-5619 BIO2007-67150-C03-02 https://creativecommons.org/licenses/by-nc/3.0/es/ open access Atribución-NoComercial 3.0 España Oxford University Press
