Fluoroscopic tumor tracking for image-guided lung cancer radiotherapy.
Accurate lung tumor tracking in real time is a keystone to image-guided radiotherapy of lung cancers. Existing lung tumor tracking approaches can be roughly grouped into three categories: (1) deriving tumor position from external surrogates; (2) tracking implanted fiducial markers fluoroscopically or electromagnetically; (3) fluoroscopically tracking lung tumor without implanted fiducial marker...
متن کاملA fast model for prediction of respiratory lung motion for image-guided radiotherapy: A feasibility study
Background: The aim of this work was to study the feasibility of constructing a fast thorax model suitable for simulating lung motion due to respiration using only one CT dataset. Materials and Methods: For each of six patients with different thorax sizes, two sets of CT images were obtained in single-breath-hold inhale and exhale stages in the supine position. The CT images were then ...
متن کاملImage - guided radiotherapy for esophageal cancer
Esophageal cancer is the eighth most common malignancy worldwide, with more than 480,000 new patients diagnosed annually. The incidence of esophageal adenocarcinoma is increasing, whereas the incidence of squamous cell carcinoma has not changed. According to the Surveillance, Epidemiology and End Results (SEER) statistics, the 5-year survival rate for esophageal carcinoma based on stage at diag...
متن کاملCarbon ion radiotherapy in a hypofractionation regimen for stage I non-small-cell lung cancer
Introduction: In 1994, we started carbon-ion radiotherapy (CIRT) for peripheral stage I non-small-cell lung cancer (NSCLC). First, two phase I/II clinical trials demonstrated the optimal doses of 90.0 GyE in 18 fractions over 6 weeks (Protocol 9303) and 72.0 GyE in 9 fractions over 3 weeks (Protocol 9701) for achieving more than 95% local control with minimal pulmonary toxicity. As a next step,...
متن کاملImage-guided prostate radiotherapy: analysis of inter- fractional setup errors
Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...
