Chapter 6 Large Patient
1 Overview
CT is an extremely valuable imaging tool for diagnosis of injury and disease. In the radiology
community, it is widely understood that very large patients (> 300 lb / 136 kg) are a challenge
for imaging due to the increase of the X-ray attenuation in this patient population. The degree of
X-ray attenuation in these large patients may degrade image quality as the patient size
increases using the same scan technique as used for normal sized patients (< 300 lb (136 kg)).
The system allows patients with weights up to 500 lb (227 kg).
This section presents the concepts necessary to successfully scan large patients.
