Abstract In Virtual Reality (VR), locomotion methods allow users to adjust their location in the virtual environment. These are sometimes used 3D-VR medical image manipulation, which has gained interest VR field due immersive environment and increased number of possible interaction techniques. However, manipulation context differs from typical locomotion, as focus is not on navigation space, but rather point view user 3D image. For this study, we recruited 24 participants find observe easy...
Purpose: In the current study, using different radiobiological models, tumor control probability (TCP) and normal tissue complication (NTCP) of radiotherapy plans were calculated for three-dimensional conformal radiation therapy (3D-CRT) intensity modulated (IMRT) prostate cancer.Methods Materials: 10 randomly selected among patients undergoing cancer. For each patient, 3D-CRT IMRT designed to deliver, on average 76 Gy 82 planning target volume, respectively. Using models including Poisson,...
Abstract Purpose: This study compares tumor control probability (TCP) and normal tissue complication (NTCP) across different hypo-fractionated (HypoRT) conventional breast radiotherapy regimens using radiobiological models. Materials methods: Computed tomography data from 30 patients with left breast-conserving surgery were used to evaluate three HypoRT (39 Gy 41·6 in 13 fractions, 40 15 fractions) a regimen (50 25 fractions). Dose-volume histograms (DVHs) extracted for calculations...
Colorectal cancer is highly prevalent worldwide and has significant morbidity mortality in humans. High-atomic-number nanoparticles such as iodine can act X-rays absorbers to increase the local dose. The synthesis fabrication of oxaliplatin-loaded nanoparticles, their characterization, cell toxicity, radiosensitivity, apoptosis, cycle assay human colorectal (HT-29) cells are investigated. Results show that a new nanoparticle, polymerized triiodobenzene coated with chitosan combined...
The main treatment modality for oropharyngeal cancer (OPC) is radiotherapy, where accurate segmentation of the primary gross tumor volume (GTVp) essential. However, GTVp challenging due to significant interobserver variability and time-consuming nature manual annotation, while fully automated methods can occasionally fail. An interactive deep learning (DL) model offers advantage automatic high-performance with flexibility user correction when necessary. In this study, we examine DL in OPC....
Glioblastoma multiforme (GBM) is the most common and malignant brain tumor. The current standard of care surgery followed by radiation therapy (RT). Radiotherapy treatment plan evaluation relies on radiobiological models for accurate estimation tumor control probability (TCP). This study aimed to assess impact obtained magnetic resonance imaging (MRI) data before 12 weeks after RT achieve optimum TCP model improve dose prescriptions in GBM.In this quasi-experimental study, MR images its...
Background and Objectives This study compared conventional dose fractionation hypofractionation in breast cancer radiotherapy to optimize treatment planning using different physical indices Subjects Methods In this retrospective study, the plans of 30 patients eligible for left-sided were investigated. Patients treated with a dose- interval regimen three hypofractionated regimens. Dosimetry indexes such as homogeneity index, conformity mean left breast, lung, heart extracted from dose-volume...
Introduction: The aim of this study was to evaluation radiobiological modeling parameters on tumor control probability (TCP) for prostate cancer in three different models. These included α⁄β ratios and cell surviving fraction at 2 Gy (SF2). Materials Methods: Poisson, equivalent uniform dose (EUD) linear quadratic (LQ) models used as the TCP calculated 10 patients a function (1.5-20) all SF2 (0.3-0.7) LQ model. For each patient, 3D-CRT IMRT plans were designed deliver, average 76 82...
Introduction: Nuclear accidents release large quantities of radioactive materials into the environment. Iodine-131 and cesium-137 are two radionuclides released during nuclear accident, which can pose greatest cancer risks. These be moved to other areas through rain wind. The aim this study was develop efficient economical biological methods for absorption water-soluble after a accident. Material Methods: exposure algae an aqueous solution I-131 radionuclide performed 1, 2, 3 h....
