Patent ID: 8804904

Claim:
A method of using imaging equipment to measure blood perfusion in a patient having a cancerous tissue, comprising: measuring a blood perfusion of contrast material in the cancerous tissue and in healthy tissue in the patient at a first examination time using a first piece of imaging equipment, to obtain a first cancer/healthy perfusion ratio result; measuring a blood perfusion of the contrast material in a healthy tissue phantom at the first examination time using the first piece of imaging equipment, the healthy tissue phantom having a known density curve selected to correspond to the blood perfusion of the healthy tissue to obtain a first phantom perfusion result; re-measuring a blood perfusion of the contrast material in the cancerous tissue and in the healthy tissue in the patient at a second examination time to obtain a second cancer/healthy perfusion ratio result using a second piece of imaging equipment; and re-measuring a blood perfusion of the contrast material in the healthy tissue phantom at the second examination time using the second piece of imaging equipment to obtain a second phantom perfusion result.
