Abstract: A system and method are provided for model-based coronary artery calcium (CAC) scoring. A model image of a heart region is aligned with an image of a patient's heart region in order to more easily identify the coronary arteries and other relevant anatomical features in the image. Once the images are aligned, relevant calcium plaques are identified by their presence within a coronary artery, and the relevant plaques are then labeled by the specific coronary artery in which they are located. The coronary arteries with the labeled plaques are scored individually based on their size and X-ray attenuation, and an overall score based on all of the relevant plaques is then computed, which is related to the patient's risk for coronary artery disease.

Abstract: A method and an apparatus for reducing electromagnetic waves in a mobile device are provided. According to the method, in a mobile device having the first and second modules with different functions, the apparatus operates the first module at the first operating frequency. If there is a request for operating the second module while the first module is operated, the apparatus changes the first operating frequency to a second operating frequency which is different from the first operating frequency, and operates the first module at the second operating frequency. The apparatus reduces a total magnitude of electromagnetic waves caused by a simultaneous operation of two or more modules, thereby enhancing the quality of the mobile device and minimizing any undesirable impact upon the human body.

Abstract: A method and an apparatus identify a spicule candidate in a medical image. The method according to one embodiment accesses digital image data representing an image including a tissue region; processes the digital image data by generating at least one line orientation map and at least one line strength map for the tissue region for at least one scale, using separable filters; calculates spicule feature values based on the at least one line orientation map and the at least one line strength map; and identifies a spicule candidate based on the calculated features values.
