Hello,

I am new to MATLAB ...

I wish to do following things ....

Read around 2000 CT images of a metal specimen.
defect in metal are dark in color. I wish to calculate the 3d size of the defect.

Please guide me for the following steps:

How to read 2000 CT images ..
how to set the threshold intensity for identification of defect in the CT image
how to calculate the 3D size of the defect and the CT image in which the 2d area of the inclusion is maximum.

This did not work.

I will try to figure out.

BTW, can you please guide me how to calculate the size of the defect

If you're not able to read your files, questions about further processing are moot. You also already received an answer from Image Analyst. Did you read it?

Can you fit the whole 3-D volumetric image into memory? If so use regionprops3 to ask for volume. If not, use regionprops to get the area of each slice and add them together. See my Fle Exchange for an image Segmentation Tutorial:
