Changing Lung CT Segmenter resampling parameter #38

Closed rbumm closed 1 year ago

rbumm commented 1 year ago

In a rodent microCT, the Lung CT Segmenter preview is blurry because the original spacing of the CT is "0.118mm". Altering the spacing in the "Volumes" extension to "1mm" solves the issue. Lung thresholds: -700 to -200 However, if 

parameters = {"outputPixelSpacing": "2.0,2.0,2.0", "InputVolume": self.inputVolume, "interpolationType": "linear", "OutputVolume": self.resampledVolume}

is changed to 

parameters = {"outputPixelSpacing": "0.4,0.4,0.4", "InputVolume": self.inputVolume, "interpolationType": "linear", "OutputVolume": self.resampledVolume}

the 3D view of the preview looks like

@lassoan I have put a link to the microCT data into discord. Would be great if you could check this.
