Segmentation of mandibular bone in CT scans is crucial for 3D virtual surgical planning craniofacial tumor resection and free flap reconstruction the defect, order to obtain a detailed surface representation bones. A major drawback most existing segmentation methods that they require large amount expert knowledge manual or partially automatic segmentation. In fact, due lack experienced doctors experts, high quality hard achieve practice. Furthermore, mandibles influenced seriously by metal...
The aim of this study was to develop and evaluate a prediction model for 2-year overall survival (OS) in stage I-IIIA non-small cell lung cancer (NSCLC) patients who received definitive radiotherapy by considering clinical variables image features from pre-treatment CT-scans.NSCLC stereotactic were prospectively collected at the UMCG split into training hold out test set including 189 81 patients, respectively. External validation performed on 228 NSCLC treated with radiation or concurrent...
Lung cancer, chronic obstructive pulmonary disease (COPD), and coronary artery (CAD) are expected to cause most deaths by 2050. State-of-the-art computed tomography (CT) allows early detection of lung cancer simultaneous evaluation imaging biomarkers for the stages COPD, based on density bronchial wall thickness, CAD, calcium score (CACS), at low radiation dose. To determine cut-off values positive tests elevated risk presence is one major tasks before considering implementation CT screening...
Accurate pulmonary nodule detection is a crucial step in lung cancer screening.Computer-aided (CAD) systems are not routinely used by radiologists for clinical practice despite their potential benefits.Maximum intensity projection (MIP) images improve the of nodules radiological evaluation with computed tomography (CT) scans.Inspired methodology radiologists, we aim to explore feasibility applying MIP effectiveness automatic using convolutional neural networks (CNNs).We propose CNN-based...
Recently, deep learning (DL) algorithms showed to be promising in predicting outcomes such as distant metastasis-free survival (DMFS) and overall (OS) using pre-treatment imaging head neck cancer. Gross Tumor Volume of the primary tumor (GTVp) segmentation is used an additional channel input DL improve model performance. However, binary mask GTVp directs focus network defined region only uniformly. models trained for have also been generate predicted probability maps (TPM) where each pixel...
Glaucoma is a chronic progressive optic neuropathy that causes visual impairment or blindness if left untreated. It crucial to diagnose it at an early stage in order enable treatment. Fundus photography viable option for population-based screening. A fundus photograph enables the observation of excavation disk—the hallmark glaucoma. The quantified as vertical cup-to-disk ratio (VCDR). manual assessment retinal images is, however, time-consuming and costly. Thus, automated system necessary...
Purpose: Classic encoder–decoder-based convolutional neural network (EDCNN) approaches cannot accurately segment detailed anatomical structures of the mandible in computed tomography (CT), for instance, condyles and coronoids mandible, which are often affected by noise metal artifacts. The main reason is that EDCNN ignore connectivity organs. In this paper, we propose a novel CNN-based 3D segmentation approach has ability to structures. Methods: Different from classic EDCNNs need slice or...
Deep learning (DL) models can extract prognostic image features from pre-treatment PET/CT scans. The study objective was to explore the potential benefits of incorporating pathologic lymph node (PL) spatial information in addition that primary tumor (PT) DL-based for predicting local control (LC), regional (RC), distant-metastasis-free survival (DMFS), and overall (OS) oropharyngeal cancer (OPC) patients. included 409 OPC patients treated with definitive (chemo)radiotherapy between 2010...
In the HECKTOR 2022 challenge set [1], several state-of-the-art (SOTA, achieving best performance) deep learning models were introduced for predicting recurrence-free period (RFP) in head and neck cancer patients using PET CT images. This study investigates whether a conventional DenseNet architecture, with optimized numbers of layers image-fusion strategies, could achieve comparable performance as SOTA models. The dataset comprises 489 oropharyngeal (OPC) from seven distinct centers. It was...

A model forced vibration dynamics trees was established, a three-dimensional constructed diameter variations. kinematic simulation analysis then conducted determine inherent frequency modal patterns trees. Harmonic response performed displacement acceleration responses with diameters factors....
Accurate mandible segmentation is significant in the field of maxillofacial surgery to guide clinical diagnosis and treatment develop appropriate surgical plans. In particular, cone-beam computed tomography (CBCT) images with metal parts, such as those used oral (OMFS), often have susceptibilities when artifacts are present weak blurred boundaries caused by a high-attenuation material low radiation dose image acquisition. To overcome this problem, paper proposes novel deep learning-based...
