There is provided a radiographic three-dimensional phantom for inter alia mimicking specific anatomical parts in a computerized tomography scan. Methods are provided for a variety of purposes including detecting a difference between a measured optical deformation of a radiographic three-dimensional phantom pair and a theoretical deformation of the radiographic three-dimensional phantom pair. These three-dimensional phantom can be divided into a plurality of portions, and non-radiopaque markers can be added to the portions. The portions of the three-dimensional phantom can be re-assembled, and images of the three-dimensional phantom can be generated and compared.

Thermoplastic 3-D phantom

The present invention offers an alternative for cancer treatment where radiation, thermotherapy, or another therapeutic modality must be delivered to an internal cavity of a subject, for example to treat mouth, anal, cervical, and vaginal cancers. The invention is a new approach that builds on recent results in 3D printing and steerable needle motion planning to create customized implants containing customized curvature-constrained internal channels that fit securely, minimize air gaps, and precisely guide treatment sources through internal printed channels to accurately reach tumors and minimize damage to healthy tissue.

Radiographic phantom apparatuses

A system includes acquisition of a three-dimensional cone beam image, and determination of a dose to be delivered based on the three-dimensional image and on parameters of a treatment beam to deliver the dose. Some systems may include modification of a three-dimensional cone beam image to correct for scatter radiation, and determination of a dose based on the modified three-dimensional cone beam image.
