Measurement uncertainty analysis of low-dose-rate prostate seed brachytherapy: post-implant dosimetry
Springer Science and Business Media LLC - Tập 38 - Trang 71-81 - 2015
Kent J. Gregory, John E. Pattison, Giovanni Bibbo
The minimal dose covering 90 % of the prostate volume—D 90—is arguably the most important dosimetric parameter in low-dose-rate prostate seed brachytherapy. In this study an analysis of the measurement uncertainties in D 90 from low-dose-rate prostate seed brachytherapy was conducted for two common treatment procedures with two different post-implant dosimetry metho...... hiện toàn bộ

Airflow, transport and regional deposition of aerosol particles during chronic bronchitis of human central airways
Springer Science and Business Media LLC - Tập 39 - Trang 43-58 - 2015
Fouad Farkhadnia, Tahereh B. Gorji, Mofid Gorji-Bandpy
In the present study, the effects of airway blockage in chronic bronchitis disease on the flow patterns and transport/deposition of micro-particles in a human symmetric triple bifurcation lung airway model, i.e., Weibel’s generations G3–G6 was investigated. A computational fluid and particle dynamics model was implemented, validated and applied in order to evaluate the airflow and particle transpo...... hiện toàn bộ
A new approach of QRS complex detection based on matched filtering and triangle character analysis
Springer Science and Business Media LLC - Tập 35 - Trang 341-356 - 2012
Yanjun Li, Hong Yan, Feng Hong, Jinzhong Song
QRS complex detection usually provides the fundamentals to automated electrocardiogram (ECG) analysis. In this paper, a new approach of QRS complex detection without the stage of noise suppression was developed and evaluated, which was based on the combination of two techniques: matched filtering and triangle character analysis. Firstly, a template of QRS complex was selected automatically by the ...... hiện toàn bộ
Effect of computed tomography number-relative electron density conversion curve on the calculation of radiotherapy dose and evaluation of Monaco radiotherapy treatment planning system
Springer Science and Business Media LLC - Tập 42 - Trang 489-502 - 2019
Mohsen Hasani, Bagher Farhood, Mahdi Ghorbani, Hamideh Naderi, Sepideh Saadatmand, Saeed Karimkhani Zandi, Courtney Knaup
The accuracy of a computed tomography (CT)-relative electron density (RED) curve may have an indirect impact on the accuracy of dose calculation by a treatment planning system (TPS). This effect has not been previously quantified for input of different CT-RED curves from different CT-scan units in the Monaco TPS. This study aims to evaluate the effect of CT-RED curve on the dose calculation by the...... hiện toàn bộ

Extraction of electron beam dose parameters from EBT2 film data scored in a mini phantom
Springer Science and Business Media LLC - Tập 36 - Trang 339-346 - 2013
Dedri O’Reilly, Cobus J. L. Smit, Freek C. P. du Plessis
Quality assurance of medical linear accelerators includes dosimetric parameter measurement of therapeutic electron beams e.g. relative dose at a depth of 80 % (R80). This parameter must be within a tolerance of 0.2 cm of the declared value. Cumbersome water tank measurements can be regarded as a benchmark to measure electron depth dose curves. A mini-phantom was designed and built, in which a stri...... hiện toàn bộ
Shift in absorbed dose for megavoltage photons when changing to TRS-398 in Australia
Springer Science and Business Media LLC - Tập 28 - Trang 159-164 - 2005
D. J. Butler, H. Palmans, D. V. Webb
Australian primary standards of air kerma and absorbed dose are realized in60Co gamma rays. To calibrate the megavoltage photon beams from linear accelerators, radiotherapy centres have their ionization chamber calibrated in a60Co beam and then use a protocol to transfer this calibration to the higher energy. The radiotherapy community is in the process of changing from the ACPSEM Protocol (Second...... hiện toàn bộ
