CT data for thorax
The images shown on this page has been obtained
from
the Visible Human Project. They were created from scanning a human
cadaver with CT and MRI scanners and then subsequently slicing the
cadaver into 1 mm sections for taking photographs.
The CT data consists of axial CT scans of the entire body taken at 1 mm
intervals at a resolution of 512 pixels by 512 pixels where each pixel
is made up of 12 bits of grey tone.
A further description of the data can be found at
here and a description of the program can be found
here.
Data for the CT-image can be obtained from the ftp-server from the
directory:
https://courses.healthtech.dtu.dk/22485/files/ct_data/thorax/
Both
the raw CT image data can be found, along with
the projected CT data for the image. The image contains 512 x 512 pixels
and the CT data contains 200 projections for 180 deg. The pixel values in the image
are from zero and up. The pixel values are equal to Hounsfield units and a pixel value of
zero corresponds to -1000 in Hounsfield units. The projected data are also off-set
1000 Hounsfield units.
