How to improve quality of STL models created from CT image


I have just got ct images and I am tring to achieve stl model in Slicer. Unfortunately there is a lot of artifacts and I don’t know how to make clear model. Do you have some program which could help me improve quality of my images?

Segment editor tutorials and recipes should help in creating good quality STL files. You may need to work harder if the input CT image is of low quality (low-resolution, noisy, etc.).
