This study aimed to evaluate the clinical effectiveness of femoral neck system (FNS) compared four cannulated compression screws (CCSs) for managing Pauwels type III fractures in young patients. A retrospective analysis was conducted on patients with treated at our hospital from January 2021 December 2022. Patients were categorized into two groups based their respective internal fixation methods: FNS group (32 cases) and CCSs (41 cases). Various demographic variables, including age, gender,...
A novel k-space reconstruction method is proposed for generating diffusion-weighted imaging (DWI) using navigated interleaved multishot EPI (msEPI).In msEPI, each shot of data acquired from one coil channel a subset the full that channel. All subsets can be treated as an undersampled dataset virtual multichannel data, which reconstructed by GRAPPA algorithm after realignment. The intershot phase variations are directly compensated navigator echoes auto-calibrating in reconstruction. In cases...
Since December 2019, many patients in Wuhan sustained pneumonia with unknown causes.[1,2] A part of severe developed acute respiratory distress syndrome or septic shock, and even death. On January 7, 2020, Chinese researchers have for the first time detected a new coronavirus. 20, National Health Commission issued Announcement No. 1 which included coronavirus as Class B infectious disease, conducted epidemic prevention control according to disease. This kind has been named disease 2019...
Purpose To develop a novel coil sensitivity processing technique that is able to reduce or eliminate aliasing artifacts and noise amplification in image‐domain parallel imaging (i.e., SENSE). Methods Initial maps were derived from the center k‐space lines by common self‐calibration method. Then continuous trigonometric functions used fit both magnitude phase of s elf‐calibrated profile globally. Further, global fitted adopted for SENSE reconstruction. Numerical simulations, as well...
Abstract MRI phase data often suffers from wrapping (i.e., may be discontinuous by 2π jumps). Numerous unwrapping strategies were developed in the past using a criterion based on information of local or neighboring voxels. In this study, an alternative and novel three dimensional strategy is introduced. This method considers global character distribution utilizes continuous trigonometric functions to construct expected map as reference, which then used guide correction every individual...
In recent years, there has been increasing demand for personalized anatomy modelling medical and industrial applications, such as ergonomics device development, clinical radiological exposure simulation, biomechanics analysis, 3D animation character design. this study, we constructed deformable torso phantoms that can be deformed to match the personal of Chinese male female adults. The were created based on a training set 79 trunk computed tomography (CT) images (41 males 38 females) from...
Purpose To develop a novel three‐dimensional (3D) sequence for susceptibility weighted imaging that is able to reduce scan time substantially while maintaining high image signal‐to‐noise ratio (SNR). Methods The proposed fast T 2 *‐weighted was based on 3D full‐balanced gradient frame and pair of crusher gradients. gradients were used shift MR signal from the repetition where originated later enhance * weighting. avoid SNR reduction due repeated excitations by RF pulses, as it would occur...
Cardiac T2 mapping is a valuable tool for diagnosing myocardial edema, inflammation, and infiltration, yet its spatial resolution limited by the single-shot balanced steady-state free precession acquisition duration of cardiac quiescent period, which may reduce sensitivity in detecting focal lesions myocardium. To improve without extending window, this study examined novel accelerated Cartesian technique.
Significant advancements in ship detection technology synthetic aperture radar (SAR) images have been made recent years due to the rapid development of deep learning technology. Nevertheless, there are still certain issues with current learning-based algorithms when detecting small-scale, arbitrary-direction, and densely packed targets SAR images. We offer a rotating target network based on improved YOLOv8 as solution these issues. First, new small sampling layer is introduced enhance...
We explore the potential of deep convolutional neural network (CNN) models for differential diagnosis gout from musculoskeletal ultrasound (MSKUS). Our exhaustive study state-of-the-art (SOTA) CNN image classification this problem reveals that they often fail to learn gouty MSKUS features, including double contour sign, tophus, and snowstorm, which are essential sonographers' decisions. In study, we establish a human-centered adjusting framework make in way thinking like sonographers. This...
Let ${\mathfrak g}$ be a finite dimensional complex simple Lie algebra, and let $r,s\in \mathbb{C}^{\ast}$ transcendental over $\mathbb{Q}$ such that $r^{m}s^{n}=1$ implies $m=n=0$. We will obtain some basic properties of the two-parameter quantized enveloping algebra $U_{r,s}^{+}(\mathfrak g)$. In particular, we verify g)$ satisfies many nice as having normal separation, catenarity Dixmier-Moeglin equivalence. shall study concrete example, $U_{r,s}^{+}(B_{2})$ in detail. first determine...
Muti-b-value Diffusion Weighted Imaging (DWI) is commonly used in clinical and neuroscientific applications. The traditional single-shot Echo-Planer (EPI) sequence suffers from low image resolution. Although the multi-shot EPI can increase spatial resolution, k-space sampling causes linearly increased scan time. An interleaved acquisition significantly reduce time; however, dynamic change of phase contrast aliasing artifacts. To improve efficiency preserve quality, an keyhole-EPI...
Aiming at the problem that solution space of mapping function from low resolution image to high is extremely large, which makes it difficult for super-resolution reconstruction models generate detailed textures, this paper proposes a single super network combining dual attention mechanism. The improved U-Net model used as basic structure, and data enhancement method introduced increase diversity samples. encoder composed convolution layer an adaptive parameter linear rectifier (Dynamic...
