A measuring device for measuring a signal with a first component signal and at least one second component signal comprises a high-frequency processing device, which is embodied to mix the signal in order to form an intermediate-frequency signal and to digitize the latter in order to form a digital composite signal. The measuring device further comprises a digital mixer, which is embodied to generate a first digital composite test signal and a second digital composite test signal subject to a displacement of the frequency of the digital composite signal. Moreover, the measuring device comprises a digital filter, which is embodied to filter the first digital composite test signal in order to form a first digital test signal and to filter the second digital composite test signal in order to form a second digital test signal.

A branch extension method and system for segmenting airways in 3D image data is disclosed. An initial airway segmentation is obtained from the 3D image data. Terminal branches of segmented airways of the initial airway segmentation are identified. The segmentation of the terminal branches is then extended. The segmentation of the terminal branches can be extended using various segmentation techniques. This method can use complex segmentation techniques to extend the terminal branches without having a large impact to the overall speed of the segmentation.

A method and system for detecting airways in 3D lung image data is disclosed. The 3D lung image data is filtered using one or more filters based on first and second order derivatives of the CT image data. Each filter calculates a value for each voxel of the 3D lung image data, and the values from all of the filters are combined to determine a voxel score for each voxel. If the voxel score for a voxel is greater than or equal to a threshold value, the voxel is considered an airway candidate.
