Distributed architecture for mammographic image acquisition and processing
View Patent ↗A distributed architecture allows for decoupling of mammographic image acquisition and review, thereby enabling more efficient use of resources and enhanced processing. In one embodiment, the system ( 100 ) includes a number of image acquisition stations ( 102 ) and a number of image review stations ( 110 ) all associated with a central server ( 104 ). The server ( 104 ) is operative to access an image repository ( 106 ), a patient information data base ( 108 ) and a number of DICOM tools ( 112 ). The invention allows for more efficient and/or more convenient use of the image acquisition equipment and image processing stations. Moreover, the distributed architecture including the central image repository provides certain processing and analysis advantages. The invention also provides certain processing and workflow enhancements that allow for a more full realization of potential digital mammography advantages.
1. A breast imaging system comprising:
an image acquisition station for acquiring an image of a patients breast and for generating a digital signal defining a first digital image of at least a portion of said patients breast;
a server coupled to the image acquisition station to:
receive the first digital image and automatically forward the first digital image to image processing tools to generate a preprocessed image; and
associate and store the first digital image and preprocessed image in an image repository.
2. The breast imaging system of claim 1 further comprising a plurality of image review stations coupled to the image repository via the server to enable concurrent viewing at at least two of the plurality of review stations of one or more of the first digital image, preprocessed image or other image.
3. The breast imaging system of claim 2 , wherein the image of the patient's breast is acquired using an imaging technology selected from a group including x-ray, photon emission tomography (PET), magnetic resonance imaging (MRI) and ultrasound, and wherein at least one additional image associated with the first digital image are stored in the image repository.
4. The breast imaging system of claim 3 wherein the at least one additional image is selected from a group of images including a processed or enhanced image and an image of the patient's breast obtained using a technique selected from a set including ultrasound, magnetic resonance imaging MRI and photon emission tomography (PET).
5. The breast imaging system of claim 4 , wherein at least one image review station comprises logic for concurrent display of the first image and the at least one additional image.
6. The breast imaging system of claim 2 further wherein automatic preprocessing of the first digital image is performed in response to protocols associated with one of a user of one of the image review stations, a user type of one of the image review stations or a review type of one of the image review stations.
7. The breast imaging system of claim 6 wherein a protocol of preprocessing is determined by monitoring acquisition and review processes of the user to heuristically learn review patterns of the user.
8. The breast imaging system of claim 1 wherein the server is further operable to monitor the preprocessed image to determine whether the preprocessed image includes a feature of interest, automatically generate an enhanced preprocessed image if the preprocessed image includes the feature, and associate and store the enhanced preprocessed image with the first digital image and preprocessed image in the image repository.
9. The breast imaging system of claim 8 wherein the feature of the preprocessed image includes a computer assisted detection annotation, and wherein the enhanced preprocessed image comprises an enlarged view of a portion of the preprocessed image including the feature.
10. The breast imaging system of claim 1 wherein the image processing tool comprises a diagnostic tool for processing digital imaging information for diagnostic purposes.
11. The breast imaging system of claim 1 wherein the image processing tool comprises a tool for optimizing luminescence of at least a portion of the first digital image.
12. The breast imaging system of claim 1 wherein the image processing tool optimizes the first digital image in accordance with an aspect ratio of a display of at least one of the image review stations.
13. The breast imaging system of claim 1 further comprising an image review station coupled to the server, the image review station having a rotatable monitor having indicators associated with at least two orientations for locking the monitor in a selected respective orientation, and wherein the image processing tools operate in response to a selected orientation indicator to rotate the first digital image to provide such that the preprocessed image is at least one of appropriately sized and orientated on the monitor.
14. The breast imaging system of claim 13 wherein the selected respective orientation is defined in an image review protocol, and varies at least once during the image review protocol.
15. The breast imaging system of claim 14 further comprising a motor for automatically moving the monitor to desired orientations during the image review protocol.
