Computed Tomography (CT, CAT)

RECIST (top) and surface (bottom) quantification of a liver tumour in CT. More details in Smeets MedIA 2010

What is it?

Computed tomography (CAT or CT) generates 3D images from the patient or subject under study using X-rays. CT allows for very quick, high-resolution and high-quality imaging. The modality is mostly limited to anatomical images, except for contrast-enhanced CT. Its high speed, high resolution and high-quality make it the favourable modality for a lot of research and clinical examinations. Novel, applications, also for quantitative imaging, are continuously introduced, e.g. with the recent introduction of dual-energy imaging.
