To describe in detail a dataset consisting of serial four-dimensional computed tomography (4DCT) and 4D cone beam CT (4DCBCT) images acquired during chemoradiotherapy 20 locally advanced, nonsmall cell lung cancer patients we have collected at our institution shared publicly with the research community.As part an NCI-sponsored study 82 4DCT 507 4DCBCT were population advanced undergoing radiation therapy. All subjects underwent concurrent radiochemotherapy to total dose 59.4-70.2 Gy using...
This work seeks to evaluate the combatting batch effect (ComBat) harmonization algorithm's ability reduce variation in radiomic features arising from different imaging protocols and independently verify published results. The Gammex computed tomography (CT) electron density phantom Quasar body were imaged using 32 chest protocols. 107 extracted 15 spatially varying spherical contours between 1.5 cm 3 each of lung300 density, lung450 wood inserts. Kolmogorov-Smirnov test was used determine...
Tumor movements should be accurately predicted to improve delivery accuracy and reduce unnecessary radiation exposure healthy tissue during radiotherapy. The tumor pertaining respiration are divided into intra-fractional variation occurring in a single treatment session inter-fractional arising between different sessions. Most studies of patients' deal with variation. Previous on hardly mathematized cannot predict well due inconstant Moreover, the computation time prediction reduced. To...

Fatal radiation pneumonitis is a rare event. In recent years, higher incidences of grade 5 have been reported. Based on 3 cases in our clinic, literature review was performed to assess specific clinical features and risk factors for fatal pneumonitis.Three patients with nonsmall cell lung cancer were treated conventionally fractionated therapy, 2 volumetric modulated arc therapy one intensity therapy. All had high volumes Gy the total contralateral lungs. Patients died between months after...
Background: We aimed to measure the pacemaker- and defibrillator-induced distortion at 0.35T 3.0T magnetic fields. Methods: The pacemaker/defibrillator was placed top center of a water-filled/MagPhan phantom, followed by T1 scan 3T TrueFISP 0.35T. extent (i.e., distance from device furthest signal loss/void/rings) in water-filled phantom measured MIM. For geometrical dislocation structures), spheres MagPhan were contoured their calculated based on manufacturing coordinate positions. Results:...
This work (i) proposes a probabilistic treatment planning framework, termed coverage optimized (COP), based on dose histogram (DCH) criteria; (ii) describes concrete proof‐of‐concept implementation of COP within the PINNACLE system; and (iii) for set 28 prostate anatomies, compares plans generated with this to traditional PTV‐based criteria approximating those in high arm Radiation Therapy Oncology Group 0126 protocol. Let denote delivered fractional volume structure. In conventional...
Adaptive ventilation guided radiation therapy could minimize the irradiation of healthy lung based on repeat imaging (VI) during treatment. However efficacy adaptive guidance requires that interfraction (e.g., week-to-week), changes are not washed out by intrafraction pre- and postfraction) changes, for example, due to patient breathing variability. The authors hypothesize patients undergoing cancer exhibit larger compared function changes. To test this, perform first comparison VI pairs...
Four-dimensional (4D) radiotherapy is the explicit inclusion of temporal changes in anatomy during imaging, planning, and delivery radiotherapy. One key component 4D planning ability to automatically ("auto") create contours on all respiratory phase computed tomography (CT) datasets comprising a CT scan, based manually drawn one image set from phase. A tool that can be used propagate scans other phases deformable registration. The purpose current study was geometrically quantify difference...
Purpose: To quantify the potential benefit associated with daily replanning in lung cancer terms of normal tissue dose sparing and to characterize tradeoff between adaptive frequency. Methods: A set synthetic images contours, derived from weekly active breathing control 12 patients who underwent radiation therapy treatment for nonsmall cell cancer, is generated each fraction using principal component analysis a way that preserves temporal anatomical trends (e.g., tumor regression). Daily...
