Composite image generation and interactive display technology

A computer implemented method for using two or more spatially coextensive images obtained, from a CT scan to create a composite image, the computer implemented method comprising:

• providing a first image comprising a plurality of voxels each representing a location in a region under study and created using a first convolution kernel with a first filtering algorithm;
• providing a second image comprising a plurality of voxels each representing a location in a region under study and created using a second convolution kernel with a second filtering algorithm, wherein at least a portion of the second image is coextensive with the first image;
• and wherein the first filtering algorithm reduces noise and spatial resolution more than the second filtering algorithm;
• and using a first set of intensity values related to x-ray attenuation to identify a first plurality of voxels and a second plurality of voxels in the first image, wherein the second plurality of voxels corresponds to voxels to be replaced;
• identifying a third plurality of voxels in the second image, wherein the third plurality of voxels in the second image spatially correspond with the second plurality of voxels in the first image;
• and creating a composite image including the first plurality of voxels from the first image, and the third plurality of voxels from the second image.
