Abstract Operator radiation and the protection efficacy of a ceiling-suspended lead screen were assessed during coronary angiography (CA) in catheterization laboratory. An anthropomorphic phantom was placed under X-ray beam to simulate patient attenuation eight CA projections. Using real-time dosimeters, dose rates measured on models mimicking primary operator (PO) an assistant. Subsequently, three commonly used positions compare efficacy. The exposure PO 2.3 227.9 (mean: 67.2 ± 49.0)...

Annual T1 stage papillary thyroid carcinoma (PTC) incidence rates continue to rise, yet the optimal treatment for this cancer type remains controversial. Central lymph node metastasis (CLNM) is a critical determinant in context of decision-making. While several prior studies have evaluated patients with clinica l T1a(cT1a) PTC, there been fewer analyses clinical T1b(cT1b) disease date. The present study was thus formulated explore predictors CLNM cT1a and cT1b PTC.A retrospective analysis...
Short-term outcomes of radiofrequency ablation for hepatocellular carcinoma using cone-beam computed tomography planning and image guidance
To assess patient radiation during catheter ablation procedures and operator differences. From 84 patients (51 males, age 63 ± 10 years) undergoing complex by three experienced operators we collected: body mass index (BMI), procedure type time, fluoroscopy dose area product (DAP), air kerma X-ray system setting (cine, collimation angiographic imaging angle). A new factor, DAP-fluoroscopy time ratio, was introduced to compare The results show the average 179 (± 57) minutes (min), 31 21) min,...
With the rapid development of large-scale integrated photonics, optical phased array (OPA) is an effective way to realize highly integrated, stable and low-cost beam control system. Achieving a large field view (FOV) in longitudinal direction without increasing fabrication cost system complexity still significant challenge OPA antennas. Here, high sensitivity scanning range antenna based on subwavelength structure proposed enhance free-space radiating efficiency by using ridge-waveguide...
Abstract Objective. Automated detection and segmentation of breast masses in ultrasound images are critical for cancer diagnosis, but remain challenging due to limited image quality complex tissues. This study aims develop a deep learning-based method that enables accurate mass images. Approach. A novel convolutional neural network-based framework combines the You Only Look Once (YOLO) v5 network Global-Local (GOLO) strategy was developed. First, YOLOv5 applied locate regions interest...
Objective: This study aims to optimize the downgrading of BI-RADS class 4a nodules by combining various sectional elastography techniques with age Materials and Methods: We performed conventional ultrasonography, strain (SE), shear wave (SWE) on patients. Quantitative parameters recorded included age, cross-sectional longitudinal area ratios (C-EI/B, L-EI/B), rate (C-SR, L-SR), overall average elastic modulus values (C-Emean1, L-Emean1), five-point (C-Emean2, L-Emean2), maximum (C-Emax,...
Suboptimal stent-graft placement at the lower anastomosis during transjugular intrahepatic portosystemic shunt (TIPS) may result in early stenosis and occlusion owing to incomplete covering of parenchymal tract by covered part stent-graft.To determine optimal portal venous projection view for TIPS potential influence vein anatomy.On 76 cirrhotic patients (48 men 28 women) selected TIPS, rotational, three-dimensional (3D), catheter-directed angiography was performed. The 3D portograms were...
The validity of effective dose (ED) in medical applications, which mostly involving partial-organ irradiation, has long been argued. We now propose a new algorithm evaluation for radiation exposure. will include Relative Volume Factors, or RVFs, to account the relative irradiated volume partially-irradiated organs, such as skin and bone marrow.To validate proposed algorithm, three ED methods were applied five neuro-imaging protocols C-arm cone-beam CT: 1) MOSFET-anthropomorphic- phantom...
