摘要:
A method includes scanning myocardial tissue of a patient with an Energy Discrimination Computed Tomography (EDCT) system to acquire data, and analyzing the acquired data for at least one of cardiac measurements, diagnosis, and prognosis after interventions.
摘要:
The present technique provides a method and system for generating tomographic mammography data and processing the data using a computer aided detection and diagnosis (CAD) algorithm. The CAD algorithm may perform various types of analysis, including segmentation, feature extraction, and feature classification. The acquired data may be processed in parallel by the CAD algorithm such that information derived from one processing path may be used to enhance or alter the processing of data in a parallel processing path. The processed data may be used to provide an enhanced mammographic image with features of interest marked for inspection by a radiologist. The features of interest may also be classified to aid the inspection by the radiologist.
摘要:
The present invention is directed to a method and apparatus of cardiac CT imaging. The present invention utilizes ECG signals as well as mechanical motion signals of a cardiac region of a subject to correlate CT data acquired of the subject with the phases of the subject's cardiac region. The present invention contemplates measuring mechanical gatings of the heart by measuring changes in pressure, sound, or blood flow acceleration within the cardiac region. The mechanical gatings are then used with ECG data to correlate acquired imaging data with phases of the cardiac region for subsequent image reconstruction.
摘要:
A method includes automatically determining at least one gating signal based on a physiological signal from a subject being imaged by an imaging system, automatically determining, based upon prior analysis and knowledge of the imaging system's capabilities, a timing of each of a plurality of exposures within a single or multiple cycles of the physiologic signal, and performing the multiple acquisitions.

A technique is disclosed for servicing complex systems. Upon detection of a serviceable condition, a system snapshot is made and stored. The snapshot may include a range of data then available on the system, particularly hardware configuration data, such as components then installed, peripherals installed, their states, and so forth. The snapshot may include data available prior to the detection of an indicator, at the time of detection and following detection, facilitating evaluation of the condition and potential responses to it.
摘要:
One or more techniques are provided for determining the overall motion of an organ of interest relative to a viewer or imager. Motion data is acquired for the organ of interest and/or for one or more proximate organs using sensor-based and/or image data-based techniques. The sensor-based techniques may include electrical and non-electrical techniques. The image data-based techniques may include both pre-acquisition and acquisition image data. The motion data for the organ of interest and proximate organs may be used to determine one or more quiescent periods corresponding to intervals of minimal motion for the organ of interest and the proximate organs. The one or more quiescent periods may be used to determine one or more gating points that may be used prospectively, i.e., during image acquisition. In addition, the one or more quiescent periods may be used to determine one or more motion compensation factors that may be used during processing and reconstruction of the acquired image data. The gating points and motion compensation factors may be used, separately or together, to reduce motion-related artifacts in the reconstructed images.

Systems, methods and apparatus are provided through which in some embodiments during backprojection of filtered two-dimensional into three dimensional image each voxel is analyzed for inconsistent contributions based on at least two criteria and each of the inconsistent contributions is either replaced or excluded from the backprojection.
摘要:
A healthcare system is provided with RF sensor modules that can be integrated into various components and subsystems or that can be retrofit. Sensors modules include a sensor adapted to detect operational data. The modules may process and store the data, and perform aggregation functions to simplify or reduce the data. The data is then collected from the modules by an RF transceiver and conveyed to downstream processing layers. The processing layers may evaluate the operation of the components or subsystems, or the overall health or functioning of the component, subsystem, or any other useful subdivision of the healthcare system.
摘要:
The present invention is directed to a method and apparatus for fusing or combining functional image data and anatomical image data. The invention, which may be carried out through user interaction or automatically, enables composite and clinically valuable images to be generated that display functional and anatomical data acquired with different imaging systems. By identifying fiducial markers on a functional data image and correlating the fiducial markers with anatomical markers or indicia on the anatomical data image, the respective images may be aligned with one another before a composite image is generated.
