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.
Spiculation Detection Method And Apparatus For Cad
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.

Abstract:
A helical CT scanner for imaging an object is provided. The helical CT scanner includes an X-ray emitter configured to emit X-ray beams towards the object, and a detector array positioned opposite the X-ray emitter, the detector array including a plurality of discrete detector blocks arranged in a two-dimensional grid, each detector block including a plurality of pixels, wherein at least one first gap is defined between adjacent detector blocks in a first direction, and wherein at least one second gap is defined between adjacent detector blocks in a second direction. The helical CT scanner further includes a processing device communicatively coupled to said detector array, said processing device configured to reconstruct an image of the object based on image data acquired using said detector array.
