Can 3D Ultrasound Be Used Reproducibly by Radiation Therapists in Partial Breast Image-Guided Radiation Therapy

2014-07-23 21:14:20 | BioPortfolio

Summary

To determine if the Clarity 3DUS (3D Ultrasound) system can be used by multiple individuals to acquire 3DUS images and produce consistent TB (Tumor Bed) shifts for breast IGRT (Image-Guided Radiation Therapy).

Description

TB Contouring The CT1, CT2, and US1 tumor beds will be manually contoured on the RM workstation by one of the study radiation therapists. Contouring will be performed using previously defined contouring guidelines. Available automatic contouring tools, including the 'interpolate' contouring function, may be utilized and contouring times will be recorded.

IGRT Assessment The patient will be set up on the breast board in treatment position. The 'ultra path' component of the Clarity system, which displays the path of the previous US acquired at CT simulation, will be used to guide the acquisition of US2. Although performed in the simulator room, the Clarity system will be used in 'treatment mode' thus simulating Clarity as it is used for IGRT. The study RT will first acquire the US2 scan. All steps following the acquisition of US2 will be performed off-line on the RM workstation without the need for further simulator or patient time.

Medical and Biotech [MESH] Definitions

The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

The collecting of fetal blood samples via ultrasound-guided needle aspiration of the blood in the umbilical vein.

A therapeutic approach, involving chemotherapy, radiation therapy, or surgery, after initial regimens have failed to lead to improvement in a patient's condition. Salvage therapy is most often used for neoplastic diseases.

Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
