Patent

CA 2449550

Images of blood vessels of a body are obtained by injecting a refraction enhancement contrast agent into the blood vessels to increase a difference in refractive indices of the blood vessels and surrounding material. The blood vessels are irradiated with a penetrating radiation, and an image of the blood vessels is generated based on detected radiation. The image has visible edge enhancement features indicating boundaries of the blood vessels.

Des images de vaisseaux sanguins d'un organisme sont obtenues par injection d'un agent de contraste qui augmente la réfraction dans les vaisseaux sanguins afin d'accroître la différence dans les indices de réfraction des vaisseaux sanguins et du matériel avoisinant. Les vaisseaux sanguins sont irradiés avec des rayons pénétrants, et une image des vaisseaux sanguins est produite à partir des rayonnements détectés. L'image comporte des caractéristiques visibles d'accentuation des contours indiquant les frontières des vaisseaux sanguins.
