Unclear documentation in demo d13_HelicalGeometry.py

Open Mr-Blue-Sky-Candy opened this issue 2 months ago • 4 comments

Some numbers about helical CT scan simulation is given in this line d13_HelicalGeometry.py

Expected Behavior

offOrigin behaviour should be specified and each of the numbers should be defined. Besides, it is hard to understand the phrase "images in the detector" in the line, '# about 256^3 images fit int he detector with this size.'. It would be helpful to elaborate this.

Moreover, in the demo, default Cone beam geometry is used with square detector array self.nDetector = np.array((128, 128)). However, helical CT scans do not have square detector arrays: In-multislice-helical-CT-systems-the-source-illuminates-a-2-D-array-of-detector-elements or image

Is that array specification correct?

Specifications

  • MATLAB/python version: 3.11
