Abstract
In a method, device and system for obtaining a medical image data set, a raw data stream is produced by a data acquisition device, the raw data stream including at least digital data of a medical raw data image set. The raw data stream is provided to a data compression device, wherein it is compressed. The compressed raw data stream is transferred to a data decompression device, wherein it is decompressed. The decompressed raw data stream is transferred to an image calculation tool, which produces a medical image data set operating on the decompressed raw data stream.
Claims10
A method for obtaining a medical image data set, using a medical raw data acquisition device, a data compression device, a data decompression device and an image calculation tool, said method comprising:
- S1) producing a raw data stream by operation of the medical raw data acquisition device until an acquisition completion criterion occurs, wherein the raw data stream comprises at least digital data of a medical raw data set;
- S2) during (S1), receiving the raw data stream of the image acquisition device with the data compression device;
- S3) also during (S1) compressing the raw data stream in the data compression device;
- S4) during at least a part of (S1), transferring the compressed raw data stream directly to the data decompression device without storage of the compressed raw data stream;
- S5) decompressing the compressed raw data stream in the data decompression device;
- S6) transferring the decompressed raw data stream directly to the image calculation tool without storage of the decompressed data stream, and producing a medical image data set by execution of a reconstruction algorithm of the image calculation tool on the decompressed raw data stream, and making the medical image data set available from the image calculation tool in electronic form as a data file.
