Method, device and system for obtaining a medical image data set
View Patent ↗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.
