Automated angular measurement for puncture angle using a computer-aided method in ultrasound-guided peripheral insertion
Physical and Engineering Sciences in Medicine - - Trang 1-11 - 2024
Haruyuki Watanabe, Hironori Fukuda, Yuina Ezawa, Eri Matsuyama, Yohan Kondo, Norio Hayashi, Toshihiro Ogura, Masayuki Shimosegawa
Ultrasound guidance has become the gold standard for obtaining vascular access. Angle information, which indicates the entry angle of the needle into the vein, is required to ensure puncture success. Although various image processing-based methods, such as deep learning, have recently been applied to improve needle visibility, these methods have limitations, in that the puncture angle to the targe...... hiện toàn bộ
Influence of field of view size and reconstruction methods on single-energy metal artifact reduction: a phantom study
Physical and Engineering Sciences in Medicine - Tập 45 - Trang 637-642 - 2022
Kunihito Tsuboi, Naoko Osaki, Yuki Ohtani, Ken Tanikawa, Masanori Kaneko
The purpose of this study was to evaluate the effect of single-energy metal artifact reduction (SEMAR) for metal artifacts using CT images reconstructed with adaptive iterative dose reduction three dimensional (AIDR3D) and advanced intelligent clear-IQ engine (AiCE) in calibration-field of view of various sizes. A prosthetic hip joint was arranged at the center of the phantom. The phantom images w...... hiện toàn bộ
Dosimetric characteristics of a thin bolus made of variable shape tungsten rubber for photon radiotherapy
Physical and Engineering Sciences in Medicine - Tập 44 - Trang 1249-1255 - 2021
Katsuya Okuhata, Mikoto Tamura, Hajime Monzen, Yasumasa Nishimura
In this study, we aim to clarify the dosimetric characteristics of a real time variable shape rubber containing tungsten (STR) as a thin bolus in 6-MV photon radiotherapy. The percentage depth doses (PDDs) and lateral dose profiles (irradiation field = 10 × 10  cm2) in the water-equivalent phantom were measured and compared between no bolus, a commercial 5-mm gel bolus, and 0.5-, 1-, 2-, and 3-mm ...... hiện toàn bộ
Preterm-term birth classification using EMD-based time-domain features of single-channel electrohysterogram data
Physical and Engineering Sciences in Medicine - Tập 44 - Trang 1151-1159 - 2021
Suparerk Janjarasjitt
Preterm birth anticipation is a crucial task that can reduce both the rate and the complications of preterm birth. Electrohysterogram (EHG) or uterine electromyogram (EMG) data have shown that they can provide useful information for preterm birth anticipation. Four distinct time-domain features (mean absolute value, average amplitude change, difference in absolute standard deviation value, and log...... hiện toàn bộ
Instruments to measure environmental and personal radiofrequency-electromagnetic field exposures: an update
Physical and Engineering Sciences in Medicine - Tập 45 - Trang 687-704 - 2022
Chhavi Raj Bhatt, Stuart Henderson, Chris Brzozek, Geza Benke
Modern human populations are exposed to anthropogenic sources of radiofrequency-electromagnetic fields (RF-EMFs), primarily to telecommunication and broadcasting technologies. As a result, ongoing concerns from some members of the public have arisen regarding potential health effects following RF-EMF exposures. In order to monitor human RF-EMF exposures and investigate potential health effects, an...... hiện toàn bộ
The current status of medical physicist certification program in Iran, compared to Turkey, China, Japan, UK, and USA
Physical and Engineering Sciences in Medicine - Tập 43 - Trang 467-471 - 2020
Navid Khaledi, Toshioh Fujibuchi, Xufei Wang, Zhao Ruifeng, Nur Kodaloglu, Farhad Samiei
A novel 3D printed curved monopole microstrip antenna design for biomedical applications
Physical and Engineering Sciences in Medicine - Tập 44 - Trang 1175-1186 - 2021
Mustafa Berkan Bicer, Emine Avsar Aydin
This paper proposes a novel and compact monopole microstrip antenna design with a three-dimensional (3D) printed curved substrate for biomedical applications. A curved substrate was formed by inserting a semi-cylinder structure in the middle of the planar substrate consisting of polylactic acid. The antenna was fed with a microstrip line, and a partial ground plane was formed at the bottom side of...... hiện toàn bộ
Commissioning measurements on an Elekta Unity MR-Linac
Physical and Engineering Sciences in Medicine - Tập 45 Số 2 - Trang 457-473 - 2022
Marcus Powers, John Baines, Robert K. Crane, Chantelle Fisher, S. M. Gibson, Linda Marsh, Bronwyn Oar, Ariadne Shoobridge, Emily Simpson‐Page, Marchant Van der Walt, Glenn de Vine
AbstractMagnetic resonance-guided radiotherapy technology is relatively new and commissioning publications, quality assurance (QA) protocols and commercial products are limited. This work provides guidance for implementation measurements that may be performed on the Elekta Unity MR-Linac (Elekta, Stockholm, Sweden). Adaptations of vendor supplied phantoms facilitat...... hiện toàn bộ
Exploring deep residual network based features for automatic schizophrenia detection from EEG
Physical and Engineering Sciences in Medicine - Tập 46 - Trang 561-574 - 2023
Siuly Siuly, Yanhui Guo, Omer Faruk Alcin, Yan Li, Peng Wen, Hua Wang
Schizophrenia is a severe mental illness which can cause lifelong disability. Most recent studies on the Electroencephalogram (EEG)-based diagnosis of schizophrenia rely on bespoke/hand-crafted feature extraction techniques. Traditional manual feature extraction methods are time-consuming, imprecise, and have a limited ability to balance accuracy and efficiency. Addressing this issue, this study i...... hiện toàn bộ
