Abstract: 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.

Abstract: Herein are described methods and tools for acquiring accurately co-registered PET and TRUS images, as well as the construction and use of PET-TRUS prostate phantoms. Ultrasound imaging with a transrectal probe provides anatomical detail in the prostate region that can be accurately co-registered with the sensitive functional information from the PET imaging. Imaging the prostate with both PET and transrectal ultrasound (TRUS) will help determine the location of any cancer within the prostate region. This dual-modality imaging should help provide better detection and treatment of prostate cancer. Multi-modality phantoms are also described.
