Abstract
In a method and a system for processing medical image data in a cloud system, image data acquired at a modality are compressed via an incremental compression and transferred in compressed form to a decompressor of the cloud system. The decompressor relays the decompression result to different processing units for incremental processor in order to provide a result that is then relayed to the modality and/or to additional computer-based instances.
Claims11
A method to process medical image data acquired at an imaging modality serving as a data source, for transfer to a cloud system for processing at the cloud system, said method comprising:
- prior to transferring said medical image data, incrementally compressing said medical image data separately in each of a plurality of compression stages of a compressor, to produce a set of incrementally compressed medical image data from each compression stage;
- transferring the sets of incrementally compressed medical image data in parallel from the data source to the cloud system;
- in the cloud system, incrementally decompressing the individual sets of incrementally compressed medical image data separately in parallel in each of a plurality of decompression stages of a decompressor, said decompression stages operating respectively with different degrees of decompression so as to produce a plurality of decompressed medical image data sets each having a different degree of compression that remains after said different degrees of decompression;
- processing the sets of decompressed medical image data respectively in parallel in different processing units of a processor in the cloud system, thereby generating a plurality of different processed images that differ in visual contact from each other due to the different degrees of decompression of the respective decompressed medical image data sets;
- transferring the processing results together from the cloud system to a recipient selected from the group consisting of the data source and an additional computer-based entity;
- and
- at said recipient, allowing a display selection to be made among said plurality of different processed images dependent on the respective different visual content of each processed image.
A system to process medical image data acquired at an imaging modality serving as a data source, for transfer to a cloud system for processing at the cloud system, said system comprising:
- a computerized data compressor configured to receive said medical image data and, prior to transferring said medical image data, to incrementally compress said image data separately in each of a plurality of processor stages of said compressor, to produce a set of incrementally compressed medical image data from each compression stage;
- a transfer unit configured to communicate with a network to transfer the sets of incrementally compressed medical image data in parallel to the cloud system;
- a computerized data decompressor in the cloud system configured to incrementally decompress the respective sets of incrementally compressed medical image data separately in parallel in each of a plurality of decompression stages of said decompressor, said decompression stages operating respectively with different degrees of decompression so as to produce a plurality of decompressed medical image data sets each having a different degree of compression that remains after said different degrees of decompression;
- a processor in the cloud system configured to process the sets of decompressed medical image data respectively in parallel in different processing units of the processor, thereby generating a plurality of different processed images that differ from each other due to the different degrees of decompression of the respective decompressed medical image data sets;
- a transfer unit in the cloud system configured to transfer the processed images together from the cloud system to a recipient selected from the group consisting of the data source and an additional computer-based entity;
- and
- said recipient comprising a recipient computer and a display in communication therewith, said recipient computer being configured to allow a display selection to be made among said plurality of different processed images dependent on the respective different visual content of each processed image.
