When to Resample? Anytime we use two datasets with different sized voxels Dicom Attributes to use 1. Slice Thickess 2. PixelSpacing (width, height) Calcuate new size out_size = [ int(np.round(original_size[0] * (original_spacing[0] / out_spacing[0]))), int(np.round(original_size[1] * (original_spacing[1] / out_spacing[1]))), int(np.round(original_size[2] * (original_spacing[2] / out_spacing[2]))..

What is Thresholding? Thresholding is a type of image segmentation. It converts an image from colour or grayscale into a binary image that is simply black and white. Overall Process of Thresholding (fixed-level thresholding) 1) load the original image 2) convert it to grayscale - grayscale images containe pixel values in the range from 0 to 1 3) de-noise image ex.blurring - not necessary, but im..

Principle of MRI 1. What kinds of nuclei can be used for MRI? Use Hydrogen atoms: sensitive to magnetic resonance and most abundant in the body (the majority of Hydrogen in Water) Atoms consist of Nucleus and Electrons Nuclei are made of protons and neutrons Nucleus have 2 properties: Spin and Charge --> magnetic moment Pairs of spins tend to cancel, so only atoms with an odd number of protons h..
