Embodiment Construction

[0072] figure 1 A flowchart of a computer-implemented method for providing an output data set from an input data set determined by a medical imaging method is shown. Additional reference below figure 2 To illustrate the method, figure 2 The algorithms and data structures used within the scope of the method are schematically shown. For the sake of clarity, the two-dimensional individual image data sets are denoted as input data sets or processing results respectively. However, the described method is also suitable for processing three-dimensional image data sets. It is also possible for the input data set to include a plurality of image data sets recorded sequentially in time, so that the processing result can correspondingly also include a plurality of image data sets. This is also not shown for clarity.

[0073] In step S1 , first an input data set 33 is provided, which has been determined by a medical imaging method, in particular as an X-ray recording, for example us...

Abstract

A computer-implemented method for providing an output data set from an input data set determined by a medical imaging method comprises the steps of: applying an algorithm (36) for reducing image noise to the input data set or an intermediate data set (35) determined from the input data set in order to determine a noise-reduced signal data set (38), determining the noise data set (39) as a difference between the input data set or the intermediate data set and the signal data set, determining a modified noise data set (43) by applying a noise processing algorithm (41) to the noise data set, and / or determining a modified signal data set by applying a signal processing algorithm (40) to the signal data set, and -determining an output data set by adding the modified noise data set to the signal data set or the modified signal data set (42) or by adding the noise data set to the modified signal data set.

Description

technical field [0001] The invention relates to a computer-implemented method for providing an output data set from an input data set determined by a medical imaging method. Furthermore, the invention relates to a computer-implemented method for data processing within the framework of medical subtraction imaging, a provision device, a medical imaging device, a computer program and a computer-readable data carrier . Background technique [0002] In the image data of medical imaging methods, due to various factors (such as depending on the imaged examination object, the specific examination performed, the imaging parameters, etc.), there may be significantly different contrasts and noise amplitudes. These significantly different contrasts and The magnitude of noise can make analysis of image data more difficult. This problem can arise especially in modern methods for dose regulation in which X-ray parameters (i.e. e.g. tube voltage, tube current, exposure time as well as ape...
