Purpose The purpose of this study is to investigate the effect different magnetic resonance (MR) sequences on accuracy deep learning‐based synthetic computed tomography (sCT) generation in complex head and neck region. Methods Four MR images (T1, T2, T1C, T1DixonC‐water) were collected from 45 patients with nasopharyngeal carcinoma. Seven conditional generative adversarial network (cGAN) models trained (single channel) combinations (multi‐channel) as inputs. To further verify cGAN...
The dual-energy CT-based (DECT) approach holds promise in reducing the overall uncertainty proton stopping-power-ratio (SPR) estimation as compared to conventional stoichiometric calibration approach. objective of this study was analyze factors contributing SPR using DECT-based and derive a comprehensive estimate range associated with treatment planning. Two state-of-the-art methods were selected implemented on Siemens SOMATOM Force DECT scanner. uncertainties first divided into five...
Due to the occult anatomic location of nasopharynx and frequent presence adenoid hyperplasia, positive rate for malignancy identification during biopsy is low, thus leading delayed or missed diagnosis nasopharyngeal malignancies upon initial attempt. Here, we aimed develop an artificial intelligence tool detect under endoscopic examination based on deep learning.An images-based detection model (eNPM-DM) consisting a fully convolutional network inception architecture was developed fine-tuned...
Currently, four-dimensional (4D) cone-beam computed tomography (CBCT) requires a 3-4 min full-fan scan to ensure usable image quality. Recent advancements in sparse-view 4D-CBCT reconstruction have opened the possibility reduce time and dose. The aim of this study is provide common framework for systematically evaluating algorithms from 1-min scan. Using framework, AAPM-sponsored SPARE Challenge was conducted 2018 identify compare state-of-the-art algorithms.A clinically realistic CBCT...
Infrared camouflage is crucial for high-temperature objects to avoid detection, and spontaneous infrared radiation also an important way dissipate heat. Therefore, selective emission has become significant the coating design of surfaces such as aircraft, which require low in atmospheric window band (3-5 µm 8-14 µm) high outside it (5-8 µm). This Letter employs a simple multilayer film structure achieve regulation material spectrum. Combining transfer matrix method genetic algorithm,...
Abstract Background Unresectable intrahepatic cholangiocarcinoma (iCCA) has a poor prognosis despite treatment with standard combination chemotherapy. We aimed to evaluate the efficacy and safety of radiotherapy in an anti-PD-1 antibody unresectable iCCA without distant metastases. Methods In this phase II study, patients histopathologically confirmed primary or postoperative recurrent metastases were enrolled. Patients received external dose ≥45 Gy (2-2.5 per fraction), followed by...
In recent years, prone mechanical ventilation has been widely used to improve oxygenation dysfunction in critically ill patients. During ventilation, the patient's face is compressed for a long time, and due difficulty changing, facial pressure injuries ocular complications are common severe. These increase patient discomfort, reduce their tolerance compliance with even cause tracheal tube displacement or dislodgement, leading significant clinical challenges. order change this situation,...
The rapid progress in underwater equipment has created a focus on low-frequency noise reduction technology. Highly efficient sound absorption at low frequencies below 500[Formula: see text]Hz is difficult to achieve with conventional acoustic materials. Based this, Helmholtz tunable sound-absorbing metasurface an embedded curved rough neck (HMCRN) proposed. introduces rubber coating and metal the hexagonal cavity. Compared traditional resonators, peak frequency of reduced 151[Formula:...
Deep learning has recently been extensively investigated to remove artifacts in low-dose computed tomography (LDCT). However, the power of transfer for medical image denoising tasks not fully explored. In this work, we proposed a residual convolutional neural network (TLR-CNN) restore LDCT images at single and blind noise levels. A was implemented effectively estimate difference between denoised its original map, noise-free obtained by subtracting map from image. The results were compared...
Abstract Background Chronic obstructive pulmonary disease (COPD) is a common respiratory and the third leading cause of death worldwide. Previous evidence has shown that acupuncture may be an effective complementary alternative therapy for stable COPD. However, large-sample, rigorously designed long-term follow-up studies still need to completed. Notably, relationship between frequency clinical efficacy in on COPD needs further validation. This study aims evaluate safety investigate...
Abstract Background Early detection of colorectal neoplasms can reduce the cancer (CRC) burden by timely intervention for high-risk individuals. However, effective risk prediction models are lacking personalized CRC early screening in East Asian (EAS) population. We aimed to develop, validate, and optimize a comprehensive model across all stages dynamic adenoma-carcinoma sequence EAS Methods To develop precision risk-stratification strategies, we developed three trans-ancestry PRSs targeting...
Polyamines are primordial, small organic polycations present in almost all cells, but their roles bacteria poorly understood. sym-Homospermidine is the dominant polyamine filamentous, N2 -fixing, heterocyst-forming cyanobacterium Anabaena sp. PCC 7120. Synthesis of homospermidine was dependent on speA (encoding arginine decarboxylase), speB (agmatinase) and speY (deoxyhypusine synthase homologue), which an unprecedented pathway. Inactivation any these genes impaired diazotrophic growth....
