Abstract: An examination marker for use in diagnostic imaging using microwaves. The examination marker includes a marker main body to be attached to an examination target. The marker main body is capable of displaying, on the marker main body, an index for use in scanning the examination target marker and is deformable following the shape of the examination target. The marker main body has a relative permittivity of 10 or less to microwaves at a frequency of 1 GHz.

Abstract: An adhesive supplementary marker that is configured to be used together with an adhesive examination marker to be attached to an examination target of image diagnosis using microwaves, and that is configured to be disposed between the adhesive examination marker and the examination target and pressed toward the examination target by the adhesive examination marker in a state in which the adhesive examination marker is attached to the examination target. The adhesive supplementary marker includes a laminate including a base film having a thickness of 20 ?m or less, and a pressure-sensitive adhesive layer configured to be attached to the examination target. The base film has a Young's modulus of 1.0 GPa or more.

Abstract: An adhesive examination marker includes a base film having a front surface and a rear surface facing away from the front surface, a pressure-sensitive adhesive layer disposed on the rear surface of the base film, and a support attached to the front surface of the base film and having a shape along at least a part of a periphery of the base film as viewed perpendicular to the front surface of the base film, the support including a band-like portion that connects two points on the periphery of the base film which face each other across a central portion of the base film.

Abstract: An examination marker is used in diagnostic imaging using microwaves, including a marker body to be adhered to a site to be examined. The marker body is configured to display an index used for scanning of the site to be examined and to deform in accordance with a shape of the site to be examined, and the marker body has a transmittance of 70% or higher to microwaves at a frequency of 2 GHz.
