Title:
INDIVIDUAL PATIENT-PURPOSE THREE-DIMENSIONAL (3D) PRINT PHANTOM PREPARATION SUPPORT DEVICE, INDIVIDUAL PATIENT-PURPOSE THREE-DIMENSIONAL (3D) PRINT PHANTOM PREPARATION SUPPORT PROGRAM, AND PHANTOM AS WELL AS INDIVIDUAL PATIENT-PURPOSE 3D PRINT PHANTOM PREPARATION/VERIFICATION SUPPORT METHOD
Document Type and Number:
Japanese Patent JP2019066689
Kind Code:
A
Abstract:
To provide an individual patient-purpose three-dimensional (3D) print phantom preparation support device that enables dose verification of a radiation therapy plan using a 3D printer on the basis of a CT image data group, and can obtain a highly-accurate phantom in which a ray attenuation ratio of an outer shape of a human body and an organization in the human body is adjustable.SOLUTION: An individual patient-purpose 3D print phantom preparation support device of the present invention is configured to: reconstruct phantom-purpose image data on the basis of a CT image data group of a patient by image data reconstruction means 5; convert the phantom-purpose image data into 3D print data; use an output material adjusted so as to have a ray attenuation ratio simulating a ray attenuation ratio of each part of the patient on the basis of the 3D print data by a 3D printer 12 to have a body surface and soft organization corresponding to the 3D print data provided; output a phantom 21 equipped with a cavity region and a loading position; fill an equivalent substance simulating the ray attenuation ratio of a bone of the patient in the cavity region of the output phantom; and prepare a finished phantom having a dose verification measurement jig loaded at the loading position.SELECTED DRAWING: Figure 1
