MULTIPURPOSE PHANTOM FOR EVALUATING 3-DIMENSION DOSE IN HEAD AND NECK EXTERNAL RADIATION THERAPY

摘要

aspect of the present invention is to achieve a head and neck radiation therapy outside of the three-dimensional dosimetry phantom of multi-purpose to, the exact dose of radiation irradiated to the target site in three dimensions to provide a measurable phantom head and neck. The present invention to solve the technical problem of the phantom is in the multi-purpose 3D dosimetry for external radiation therapy, including the sub-phantom space for mounting the dosimeter; And a lower main phantom including the lower sub-phantom insertion port to insert the sub-phantom; Providing a multi-purpose three-dimensional phantom for dosimetry, including, and further, on the lower main doedoe combination phantom, comprising an upper sub-top main phantom phantom insertion port to insert the sub-phantom; And may further include. According to the above present invention, the head and neck radiation multipurpose external phantom for 3D dosimetry of the treatment is separated into upper and lower phantom phantom, by using the phantom position adjustment, but the dose measurement is possible for each of the neck region or head region, ion Do absolute dosimetry, the two-dimensional dose distribution measurement using the film, the three-dimensional dose distribution can be measured using a dosimeter using a gel, it is possible to easily and accurately parlor the dose distribution, quality control of the patient that can be precisely it is effective. ;
