This paper introduces VisualQuest, a novel image dataset designed to assess the ability of large language models (LLMs) interpret non-traditional, stylized imagery. Unlike conventional photographic benchmarks, VisualQuest challenges with images that incorporate abstract, symbolic, and metaphorical elements, requiring integration domain-specific knowledge advanced reasoning. The was meticulously curated through multiple stages filtering, annotation, standardization ensure high quality...
Recent studies have suggested an association between elevated pelvic incidence (PI) and the development of lumbar spondylolysis. However, there is still lack investigation for Han Chinese people concerning normal range spinopelvic parameters relationship abnormal sagittal diseases. The objective study was to investigate lumbosacral adult spondylolysis patients in population.A total 52 with symptomatic treated General Hospital Armed Police Force (Beijing, China) were identified as group. All...
Long bone fractures are a type of physical damage with high incidence rates that have serious impacts on the normal lives humans.How to obtain preoperative internal fixation plate model before cutting muscle has become critical issue.In this paper, we present new personalized modeling system for plates in long fracture surgery. This can achieve straight semi-automatic processing from CT images 3D models. First, broken bones separated images. Second, axes extracted using Third, vertices...
Abstract Comminuted fractures are orthopedic traumas with greater surgical difficulty. In clinical treatment, a great challenge is precise reduction of multiple broken bone fragments; Another personalized and internal fixation after reduction. For these two issues, we designed an automated method framework for comminuted fractures. First, the Gaussian mixture model (GMM) used to distinguish section points noise in model; Second, ellipse fitting carried out achieve matching descriptor...
Convolution is widely used in scientific computational fields such as digital image processing and machine learning. However, these applications are difficult to execute realtime because they computationally intensive. This paper introduces a high-speed convolution solution that runs on our self-developed multicore signal processor (DSP). To optimize the capability, we propose instruction micro architecture design of subcore. As coprocessor, designed subcore integrated into network-on-chip...
Ankylosing spondylitis (AS) with an Andersson lesion may cause kyphosis. As the disease progresses, kyphosis gradually worsens. When conservative treatment does not improve symptoms, surgery is often needed to correct deformity. The optimal surgical approach for ankylosing remains controversial. Here, we introduce our procedure of pseudoarticular debridgement and osteotomy apical vertebrae Cobb angle. We found that both associated symptoms improved significantly after 13 months follow-up.
Abstract Background The surgical treatment of acetabular fracture has adverse outcomes and high risk, minimally invasive method is a good way to reduce complications improve hip joint function. This study investigate the certain fractures primarily involving anterior column quadrilateral plate using limited pararectus approach anatomical plates. Methods A consecutive cohort 17 patients with displaced were managed operatively Ten had fractures, 1 patient wall fracture, 4 transverse 2...
In this paper, a framework to visualize and model internal fixation plates is presented for computer-aided personalized minimally invasive curved bone fracture surgery.We focus on reverse reconstruction of the plate based three-dimensional (3-D) mesh models obtained from 3-D optical scanner. The steps method are as follows. First, principal component analysis K-means used reconstruct Bezier curve (ridge line) broken bones. Second, geometric shape bones, capsule projection bones proposed...
In order to optimize the recognition accuracy of maize kernels breakage detection and improve efficiency breakage, this paper using computer vision technology detecting based on K-means clustering algorithm. First, collected RGB images are converted into Lab images, then original clarity evaluation evaluated by energy function Sobel 8 gradient. Finally, different pixel acquisition equipments shooting angles. paper, broken identified color difference between integrity kernels. The angles...
BACKGROUND:Trapezoidal changes of the vertebral body are more common in patients with lumbar spondylolisthesis than others. However, we lack an understanding factors predisposing to development a marked trapezoidal deformity. Also, no associations between vertebrae (TV) and spine-pelvis sagittal parameters have been previously reported. MATERIAL AND METHODS:A total 73 subjects were enrolled collected their clinical data. Vertebral alignment measured via spine X-ray. Using index (LI), divided...
Recognition of malposition and location high-temperature forgings play a critical role in the realisation robotised die forging, which is an ongoing trend intelligent manufacturing. This study aimed at forging scraper beam armoured face conveyor, only transporting equipment used coal mine workface. Firstly, novel process to recognise using two monocular cameras, one placed horizontally another vertically, proposed. Secondly, image preprocessing algorithm combining algorithms grey linear...
As a recent research hot issue, obtaining the accurate 3 D organ models of Visible Human Project (VHP) has many significances. Therefore, how to extract regions interest (ROI) in large-scale color slice image data set become an urgent issue be solved. In this paper, we propose method framework based on OneCut algorithm and adjacent geometric features continuously main is proposed. This mainly contains two parts: firstly, used segment ROI target current image; secondly, foreground (obtained...
Abstract The aim of the study was to evaluate clinical effect limited area decompression, intervertebral fusion, and pedicle screw fixation for treating degenerative lumbar spinal stenosis (DLSS) with instability. Hemilaminectomy DLSS instability as control group. Follow-up 54 patients (26 males 28 females; average age, 59.74 ± 10.38 years) treated by (LIFP group), 52 group hemilaminectomy (HIFP group). We assessed according patients’ functional outcome grading (good excellent, fair, or...
Background: In some medical applications (e.g., virtual surgery), standard human organ models are very important and useful. Now that real body slice image sets have been collected by several countries, it is possible to obtain models. Introduction: Understanding how abandon the traditional model construction method of Photoshop sketching directly extracting 3D from volume images has an interesting challenging issue. this paper, a color matting proposed segment Methods: First, scope known...
Abstract: With the rapid development of computer technology, surgical training, and digitalized teaching human body morphology are gaining prominence in medical education. Accurate, true organ models essential digital material for these computer-assisted systems. However, no direct three-dimensional (3D) model acquisition method currently exists. Thus, extraction interested based on existing Virtual Human Project (VHP) image set is urgently needed. In this paper, a closed-form solution-based...
BACKGROUND: There is a great demand for the extraction of organ models from three-dimensional (3D) medical images in clinical medicine diagnosis and treatment. OBJECTIVE: We aimed to aid doctors seeing real shape human organs more clearly vividly. METHODS: The method uses minimum eigenvectors Laplacian matrix automatically calculate group basic matting components that can properly define volume image. These then be used build foreground with help few user marks. RESULTS: propose direct 3D...
Duplicated inferior vena cava with bilateral iliac vein compression is extremely rare. We report a case of an 87-year-old man presented lower extremity swelling, who was noted to have duplicated cava, as revealed by computed tomography angiography (CTA). This caused surrounding structures. Anticoagulant treatment combined stent implantation completely alleviated this chronic debilitating condition during the follow-up 2 months no recurrence.
