The balloon of the radiation impermeability which has the compound wall which possesses the inner layer of the balloon and the radiation impermeability adhesive which comes in contact with outside formation. The radiation impermeability adhesive whether or not you use the contrast medium of radiation impermeability in order to make the balloon expand offers the radiation transmitted image of the balloon wall of regardless. As the balloon expands, with the radiograph a thinner image is offered, the edge of the balloon image becomes clear, as for entire radiation impermeability of the balloon, the balloon expanding, does not change. In addition, the manner which the radiation impermeability adhesive between manner and two balloon wall layers which the balloon wall image pickup are done image pickup is done is offered.< Choice figure >Drawing 3バルーンの内層および外層に付着する放射線不透過性接着剤を有する複合壁をもつ放射線不透過性のバルーン。放射線不透過性接着剤は、バルーンを膨張させるために放射線不透過性の造影剤を使用するかどうかにかかわらず、バルーン壁の放射線透過画像を提供する。バルーンが膨張するにつれて、放射線写真ではより薄い画像が提供され、バルーン画像の縁部が明確になり、バルーンの総放射線不透過性は、バルーンが膨張しても変化しない。また、バルーン壁を撮像する方法および2つのバルーン壁層間の放射線不透過性接着剤を撮像する方法が提供される。【選択図】図3
