Autor: M. Roch, F. Garcia-Vicente, D. Hernandez, P. Castro, Almudena Zapatero, Margarita Chevalier

Publikováno v: Clinical and Translational Oncology. 23:2293-2301

The objective of this study was to evaluate the dosimetric impact on hypofractionated prostate radiation therapy of two geometric uncertainty sources: rectum and bladder filling and intrafractional prostate motion. This prospective study included 544

Application of discrete cosine transform to assess the effect of tumor motion variations on the definition of ITV in lung and liver SBRT

Autor: F. Garcia-Vicente, L.M. Núñez, Margarita Chevalier, D. Sevillano

Publikováno v: Physica Medica. 84:132-140

Purpose To use Discrete Cosine Transform to include tumor motion variations on ITV definition of SBRT patients. Methods Data from 66 patients was collected. 2D planar fluoroscopy images (FI) were available for 54 patients. Daily CBCT projections (CBC

Definition of internal target volumes based on planar X‐ray fluoroscopic images for lung and hepatic stereotactic body radiation therapy. Comparison to inhale/exhale CT technique

Autor: Margarita Chevalier, Luis Miguel Núñez, F. Garcia-Vicente, D. Sevillano

Publikováno v: Journal of Applied Clinical Medical Physics

Purpose To compare tumor motion amplitudes measured with 2D fluoroscopic images (FI) and with an inhale/exhale CT (IECT) technique Materials and methods Tumor motion of 52 patients (39 lung patients and 13 liver patients) was obtained with both FI an

Impact of rectum and bladder anatomy in intrafractional prostate motion during hypofractionated radiation therapy

Autor: L. Perez, D. Hernandez, P. Castro, D. Büchser, Margarita Chevalier, M. Roch, C. Anson, Almudena Zapatero, F. Garcia-Vicente

Publikováno v: Clinicaltranslational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico. 21(5)

The objective was to determine the magnitude of the prostate intrafractional motion relative to bony pelvis anatomy, and to evaluate the relationship between this displacement and some clinical and anatomical variables.The prospective study consisted
