Load images

In this chapter, we'll work with sections of a computed tomography (CT) scan from The Cancer Imaging Archive. CT uses a rotating X-ray tube to create a 3D image of the target area.

The actual content of the image depends on the instrument used: photographs measure visible light, x-ray and CT measure radiation absorbance, and MRI scanners measure magnetic fields.

To warm up, use the imageio package to load a single DICOM image from the scan volume and check out a few of its attributes.
