We have witnessed large growth within the CT Scanner industry. They provide greater tools that allow the expert many chances to perform extensive studies. However all equipment is not created equal. Below is a chart that reflects the key differences and similarities of the GE LightSpeed Pro 32 and the Philips Brilliance CT 40.
