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.

A technique is provided for enhancing performance of computer-assisted data operating algorithms in a medical context. Datasets are compiled and accessed, which may include data from a wide range of resources, including controllable and prescribable resources, such as imaging systems. The datasets are analyzed by a human expert or medical professional, and the algorithms are modified based upon feedback from the human expert or professional. Modifications may be made to a wide range of algorithms and based upon a wide range of data, such as available from an integrated knowledge base. Modifications may be made in sub-modules of the algorithms providing enhanced functionality. Modifications may also be made on various bases, including patient-specific changes, population-specific changes, feature-specific changes, and so forth.

A technique is provided for offering feedback, including feedback for patient care and for training purposes for medical professionals and human operators. The technique includes accessing data, such as image data, for evaluation by a human operator. The data is then analyzed via a computer-assisted data operating algorithm, and the analysis may further include analysis of supplemental data accessed from an integrated knowledge base. Based upon the analysis feedback is provided to the operator, such as for completing or complementing the evaluation, correcting analysis by the human operator, or otherwise informing the human operator of similarities or differences between the analyses.
摘要:
A technique for reconciling two or more reads of an image data set. One or more computer implemented routines is employed to provide computer-assisted reconciliation (CAR) including resolution of discrepancies between the two or more reads. The computer-assisted reconciliation may optimally display the discrepancies, the concurrences and any associated information to a human reconciler, may resolve the discrepancies in a partially automated manner, or may resolve the discrepancies in a fully automated manner. The reconciled data may then be provided to an end user.

The invention provides a technique for acquiring subsequent image data in a medical diagnostic context based upon analysis of initial image data. The initial image data is processed via a computer aided diagnosis algorithm to determine whether additional image data acquisition is appropriate. Subsequent acquisition processes may be performed on the same imaging system from which the initial image data originated, or a different imaging system. The imaging systems may also be of different modalities. The subsequent acquisition of image data may be performed automatically without operator intervention, or the prescribed subsequent acquisition sequence may be outputted by the system for execution upon command of an operator.
摘要:
An image processing system includes a dataset generator within an image controller generating a first derived member of a first dataset from an acquired member of the first dataset. The dataset generator further generates a first derived member of a second dataset from an acquired member of the second dataset. Temporal comparators within the image controller compare the first derived member of the first dataset and the first derived member the second dataset and generate a comparison signal therefrom.
摘要:
A technique is provided for analysis of image datasets acquired at different points in time. Computer aided algorithms are implemented for identification and classification of features of interest, and for comparison of such features which have evolved over time as represented by the image data. The algorithms may be specifically adapted to analyze temporal change images. Such algorithms may also be used to efficiently launch temporal change analysis only when particular features of interest are possibly present in the image data.
摘要:
The present technique provides a variety of processing schemes for decomposing soft tissue and bone images more accurately from low and high-energy images acquired from an imaging system, such as a dual-energy digital radiography system using flat-panel technology. In particular, a parameter selection process is provided for automatically computing the decomposition parameters WS and WB to create soft tissue and bone images, respectively. The parameter selection process modifies a default decomposition parameter based on a variety of image and technique variables, such as intensity levels of the low and high-energy images, the patient size, and the collimator filtration setting. The parameter selection process avoids robustness problems associated with image-based algorithms, and the process may operate without any direct user interaction.

摘要:
A method of creating and displaying images resulting from digital tomosynthesis performed on a subject using a flat panel detector is disclosed. The method includes the step of acquiring a series of x-ray images of the subject, where each x-ray image is acquired at different angles relative to the subject. The method also includes the steps of applying a first set of corrective measures to the series of images, reconstructing the series of images into a series of slices through the subject, and applying a second set of corrective measures to the slices. The method further includes the step of displaying the images or slices according to at least one of a plurality of display options.
