STENT HOLDING APPARATUS FOR MEASURING DOSE PERTURBATION OF EXTERNAL BEAM RADIATION FROM STENT

摘要

According to the present invention, disclosed is a stent fixing apparatus for measuring dose perturbation caused by a stent. The stent fixing apparatus according to the present invention includes: a lower housing including a lower groove formed therein to correspond to a half of a stent shape so that the stent can be received; and an upper housing including an upper groove formed therein to surround the stent by corresponding to the remaining half of the stent shape. The lower housing further includes a lower slit which is located adjacently to the lateral side of the lower groove formed therein so that a dose distribution measurement film can be inserted into the lower slit. The upper housing further includes an upper slit in a position facing the lower slit on the lateral side of the upper groove formed therein so that the dose distribution measurement film can be inserted into the upper slit. Accordingly, the present invention can quantify a dose size.
