[Problem] To provide a device for detecting fluid flow rate, the device being capable of obtaining assessments that are medically appropriate. [Solution] The velocity of a fluid flowing in a luminal tissue inside a living body is determined. Vtheta(r, theta) = w.V- theta + (1-w).V+ theta is computed to compute a calculated value Vtheta(r, theta) for the fluid flow rate of the component orthogonal to the direction of the ultrasound beam. For at least a previously determined distance from one wall of the tissue, the weight (w) here is a value that is proportional to the distance (d) from the one wall and for a previously determined distance from the other wall of the tissue, the weight is proportional to the distance (d') from the other wall. |
