Because the functions of the blood vessels include supplying all organs and tissues of the body with oxygen and nutrients, removal of waste products, fluid balance, and other functions, conditions that affect the vascular system may affect the part(s) of the body supplied by a particular vascular network, such as the coronary arteries of the heart.
System for Processing Medical Image data to Provide Vascular Function Information
A system creates a visually (e.g., color) coded 3D image that depicts 3D vascular function information including transit time of blood flow through the anatomy. A system combines 3D medical image data with vessel blood flow information. The system uses at least one repository for storing, 3D image data representing a 3D imaging volume including vessels, in the presence of a contrast agent and 2D image data representing a 2D X-ray image through the imaging volume in the presence of a contrast agent. An image data processor uses the 3D image data and the 2D image data in deriving blood flow related information for the vessels. A display processor provides data representing a composite single displayed image including a vessel structure provided by the 3D image data and the derived blood flow related information.

ActiveUS20080119741A1Improve performanceAutomatically determineBlood flow measurement devicesEvaluation of blood vesselsBlood pressure cuffsUltrasonic sensor
A method and system for use in measuring the endothelial dysfunction utilizing flow mediated dilation and determining arterial health of a patient. The system includes a non-invasive blood pressure monitor, an ultrasound system and a pulse oximeter monitor that all communicate with each other to perform the flow mediated dilation. Initially, the ultrasound transducer, blood pressure cuff and pulse oximeter sensor are positioned on an arm of the patient. The blood pressure cuff is inflated to occlude an artery for an occlusion period. Following the occlusion period, the ultrasound system is automatically signaled to begin determining a parameter of the artery, such as diameter, and the flow rate of blood through the artery without any operator intervention. At the same time, the pulse wave velocity PWV is calculated between the ultrasound transducer and the finger probe of the pulse oximeter following the occlusion period. Based upon the detected characteristics of the artery before and after occlusion, as well as the PWV, the system can determine the endothelial dysfunction and arterial health of the patient.
