A method for selective detection, with a thermographic plate, of traces of blood flow that differ from traces with a correct course in vessels at different depths, particularly of the breast, which consists in that a sequence of thermographic images is taken which are acquired by a thermographic plate gently pressed against the skin, which is cooled before each photograph with an air jet whose duration is correlated to the depth of the portion of vessel being investigated, the traces of vessels with a correct course having a substantially centripetal direction with respect to the breast and tapering toward the center of the organ so as to confirm a temperature of the blood flow which decreases because the vessel gradually branches and because the depth from the surface of the skin increases.感熱プレートを用いて、様々な深さにある血管の正常な経路の軌跡とは異なる血流の軌跡、特に乳房の血流の軌跡を選択的に検出する方法において、乳房の略中心へと向かっていて、器官の中心に向けて先細りとなっており、血管が次第に分岐すると共に肌からの深さが増大するにつれて血流の温度低下を確認することができるものを正常な経路の血管の軌跡とし、検査対象の血管の位置する深さに相関した継続時間でエアジェットにより肌を冷却する度に、肌に押しつけた感熱プレートによって得られる一連のサーモグラフィ画像を撮影する。【選択図】図１Ａ
