Body Scans(身体扫描)研究综述
Body Scans 身体扫描 - Twelve healthy male subjects were registered and divided into two groups (370 or 555 MBq of [11C]K-2), followed by 2 h whole-body scans. [1] OBJECTIVE The aim of this study was to investigate whether digitally re-posing three-dimensional optical (3DO) whole-body scans to a standardized pose would improve body composition accuracy and precision regardless of the initial pose. [2] Whole-body scans were obtained using a gamma camera during a 24-h follow-up. [3] Nineteen patients with complete sets of planar whole-body scans over at least four days and a single SPECT/CT after 200 MBq 177Lu-Pentixather were included. [4] The aim of this study is to identify a relatively reliable gating method for CBM whole-body scans with respect to breathing pattern variability. [5] Therapeutic and diagnostic I-131 whole-body scans were negative for any I-13-avid lesions. [6] For this feasibility study, we compared areal surface roughness characteristics, assessed from 3D photonic full-body scans of 76 Swiss young men, and compared the results with body impedance-based estimates of relative body fat. [7] Using these generated labels, we then train an attention-based, multi-task CNN architecture to detect and estimate the location of abnormalities in whole-body scans. [8] We have retrospectively analyzed the pre-therapy 68Ga-PSMA positron-emission tomography (PET)-computed tomography (CT) and post-therapy planar whole-body scans of 65 patients who received at least two cycles of 7. [9] In this study, we use novel data, called CAESAR, which contains three-dimensional (3D) whole-body scans to mitigate possible reporting and measurement errors. [10] Rather than total-body PET/CT scans from head to toe, regular whole-body scans (from skull-base to thighs on the SAFOV Biograph Vision scanner, or vertex to thighs on the LAFOV Biograph Vision Quadra scanner) were performed. [11] Furthermore, our network is generalizable for segmenting the whole neural system in full-body scans, and works in tests on distantly related and morphologically divergent insects (e. [12] The body scans were reviewed qualitatively by a blinded nuclear medicine radiologist. [13] We further boost the performance by using self-supervision on whole-body scans to learn the general feature representation of normal tissue, by which CNN models will be able to further understand the recognition of lesions in CT scans. [14] On anterior and posterior whole-body scans (Figure 1 A and B), diffuse cardiac, hepatic, and soft-tissue uptake of the radiotracer was seen, in association with low skeletal uptake. [15] Methods: Fourteen prospectively enrolled ovarian cancer patients were injected with 18F-FTT and imaged dynamically for 60-minutes post-injection followed by up to two whole-body scans, with venous blood activity and metabolite measurements. [16] Additional care needs to be taken when using body scans during mindfulness as they have the potential to exacerbate psychological distress in people with reduced sensory awareness. [17] Biodistribution and dosimetry were examined by whole-body scans. [18] For each patient scan, the SSDE was obtained using Dw and CTDIvol values of each scan, according to AAPM Report 220 for body scans and Report 293 for head scans. [19] Serum Tg is a useful test along with radioactive whole-body scans to distinguish local disease, loco-regional disease, and distant metastasis. [20] The thyroiditis group had lower neck counts in both Early and Delayed whole-body scans (WBS), and higher reduction rates than the thyroiditis-absent group. [21] Based on a left arm biopsy and whole-body scans, he was eventually diagnosed with CRMO. [22] Spot images typically provide superior spatial resolution and enhanced lesion detection compared to whole-body scans using the same equipment. [23] Changes are compatible with the measurement ratios from the body scans, indicating that some of the increases in women’s waist measurements may be attributable to the decreased use of shapewear. [24] Serial whole-body scans were acquired at 24, 48, and ≥ 72 h after administration of iodine-131. [25] This template model consists of vertices, joints and skinning weights learned a priori from registered full‐body scans, representing true human shape and kinematics‐based shape deformations. [26] The designer used body scans of a fit model in both standing and seated positions to develop half-scale dress forms. [27] We validate our method using the 2012 Canadian Forces Anthropometric Survey (CFAS) dataset where 2,200 full-body scans were collected. [28] Background99mTc-labelled methylene diphosphonate (99mTc-MDP) uptake can occasionally be identified in extraosseous neoplasms on whole-body scans (WBSs) and may be misinterpreted as bone metastasis. [29] Recent approaches for full-body reconstruction use a statistical shape model, which is built upon accurate full-body scans of people in skin-tight clothes. [30] This paper presents the results of predicting anthropometric measurements from three-dimensional (3D) body scans based on the data from the US Army anthropometric survey 2012 (ANSURII). [31] Through stepwise mental “body scans” one can see that by simply changing focus the mental cycles and sensations they create are impermanent and subside. [32] Spot images typically provide superior spatial resolution and enhanced lesion detection compared with whole-body scans using the same equipment. [33] Longitudinal whole-body scans, demonstrated efficient viral uptake in pancreatic Suit-2 and Panc04. [34] Among patients with a disease stage justifying thyroid remnant ablation or with suspected metastatic disease, radioiodine whole-body scans are essential in the months after surgery. [35] You could use radioactivity and whole-body scans to evaluate different organs––often at the same time. [36] Serial whole-body scans and SPECT/CT are taken at 1, 4, 8, 24, 48, and 72 h after intravenous injection of 111 MBq of 188Re-liposome. [37] This study aims to quantitatively evaluate the cumulative effective dose and associated cancer risk of pediatric patients of US and Hong Kong population undergoing repetitive whole-body scans with dual-energy X-ray absorptiometry (DXA) during their diagnosis and follow-up periods. [38] However, men became more negative about their bodies as a result of seeing their body scans, so scanning needs to be carried out with supervision and support. [39] RESULTS Our method is tested by using low-dose unenhanced computed tomography (CT) images of 180 near whole-body 18 F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scans (including 34 whole-body scans) which are randomly divided into training and testing sets with a ratio of 85%:15%. [40] 3D full-body scans were taken using a 3dMD scanner, body composition data measured using a Tanita bio-impedance scale and physical measurements (chest, waist, hip and arm circumference) taken using a tape measure. [41]登记 12 名健康男性受试者并分为两组（370 或 555 MBq 的 [11C]K-2），然后进行 2 小时全身扫描。 [1] 客观的 本研究的目的是调查以数字方式将三维光学 (3DO) 全身扫描重新定位为标准化姿势是否会提高身体成分的准确性和精度，而不管初始姿势如何。 [2] 在 24 小时的随访期间，使用伽马相机进行全身扫描。 [3] 19 名患者在至少 4 天内完成了完整的平面全身扫描，并在 200 MBq 177Lu-Pentixather 后进行了单次 SPECT/CT。 [4] 本研究的目的是确定一种相对可靠的 CBM 全身扫描门控方法，以了解呼吸模式的变异性。 [5] 治疗性和诊断性 I-131 全身扫描对任何 I-13-avid 病变均呈阴性。 [6] 在这项可行性研究中，我们比较了表面粗糙度特征，对 76 名瑞士年轻男性进行了 3D 光子全身扫描评估，并将结果与基于身体阻抗的相对体脂估计进行了比较。 [7] 然后，使用这些生成的标签，我们训练了一个基于注意力的多任务 CNN 架构，以检测和估计全身扫描中异常的位置。 [8] 我们回顾性分析了接受至少两个周期的 7 的 65 名患者的治疗前 68Ga-PSMA 正电子发射断层扫描 (PET)-计算机断层扫描 (CT) 和治疗后平面全身扫描。 [9] 在这项研究中，我们使用称为 CAESAR 的新数据，其中包含三维 (3D) 全身扫描，以减少可能的报告和测量错误。 [10] 不是从头到脚进行全身 PET/CT 扫描，而是进行定期全身扫描（在 SAFOV Biograph Vision 扫描仪上从颅底到大腿，或在 LAFOV Biograph Vision Quadra 扫描仪上从头顶到大腿）。 [11] 此外，我们的网络可推广用于在全身扫描中分割整个神经系统，并适用于远亲和形态上不同的昆虫（例如。 [12] 身体扫描由不知情的核医学放射科医生定性审查。 [13] 我们通过在全身扫描中使用自我监督来学习正常组织的一般特征表示，从而进一步提高性能，CNN 模型将能够进一步了解 CT 扫描中对病变的识别。 [14] 在全身前部和后部扫描（图 1 A 和 B）中，可见放射性示踪剂在心脏、肝脏和软组织的弥漫性摄取，与骨骼摄取低有关。 [15] 方法：14 名前瞻性登记的卵巢癌患者被注射 18F-FTT，并在注射后 60 分钟动态成像，然后进行多达两次全身扫描，包括静脉血活性和代谢物测量。 [16] 在正念期间使用身体扫描时需要格外小心，因为它们有可能加剧感官意识下降的人的心理困扰。 [17] 通过全身扫描检查生物分布和剂量测定。 [18] 对于每次患者扫描，根据 AAPM 报告 220 的身体扫描和报告 293 的头部扫描，使用每次扫描的 Dw 和 CTDIvol 值获得 SSDE。 [19] 血清 Tg 与放射性全身扫描一起是一种有用的测试，以区分局部疾病、局部区域疾病和远处转移。 [20] 甲状腺炎组在早期和延迟全身扫描 (WBS) 中的颈部计数均较低，而减少率高于无甲状腺炎组。 [21] 根据左臂活检和全身扫描，他最终被诊断出患有 CRMO。 [22] 与使用相同设备的全身扫描相比，点图像通常提供卓越的空间分辨率和增强的病变检测。 [23] 变化与身体扫描的测量比率相符，这表明女性腰围的一些增加可能归因于塑身衣的使用减少。 [24] 在 iodine-131 给药后 24、48 和 ≥ 72 小时进行系列全身扫描。 [25] 该模板模型由从注册的全身扫描中先验学习的顶点、关节和蒙皮权重组成，代表真实的人体形状和基于运动学的形状变形。 [26] 设计师使用站立和坐姿的合身模特的身体扫描来开发半比例的礼服形式。 [27] 我们使用 2012 年加拿大军队人体测量调查 (CFAS) 数据集验证了我们的方法，该数据集收集了 2,200 次全身扫描。 [28] 背景 99mTc 标记的亚甲基二膦酸盐 (99mTc-MDP) 摄取偶尔可以在全身扫描 (WBS) 的骨外肿瘤中发现，并可能被误解为骨转移。 [29] 最近的全身重建方法使用了一种统计形状模型，该模型建立在对穿着紧身衣服的人进行准确的全身扫描的基础上。 [30] 本文介绍了根据 2012 年美国陆军人体测量调查 (ANSURII) 的数据预测三维 (3D) 身体扫描的人体测量结果。 [31] 通过逐步的心理“身体扫描”，人们可以看到，通过简单地改变焦点，它们产生的心理周期和感觉是无常的和消退的。 [32] 与使用相同设备的全身扫描相比，点图像通常提供卓越的空间分辨率和增强的病变检测。 [33] 纵向全身扫描显示胰腺 Suit-2 和 Panc04 有效吸收病毒。 [34] 在疾病阶段证明残留甲状腺消融或疑似转移性疾病的患者中，放射性碘全身扫描在手术后的几个月内是必不可少的。 [35] 您可以使用放射性和全身扫描来评估不同的器官——通常是同时进行。 [36] 在静脉注射 111 MBq 的 188Re-脂质体后 1、4、8、24、48 和 72 h 进行系列全身扫描和 SPECT/CT。 [37] 本研究旨在定量评估美国和香港儿童患者在诊断和随访期间接受双能 X 射线骨密度仪 (DXA) 重复全身扫描的累积有效剂量和相关癌症风险。 [38] 然而，男性在看到他们的身体扫描后对自己的身体变得更加消极，因此扫描需要在监督和支持下进行。 [39] 结果 我们的方法通过使用 180 个近全身 18 F-氟脱氧葡萄糖-正电子发射断层扫描/计算机断层扫描 (FDG-PET/CT) 扫描（包括 34 个全身扫描）的低剂量非增强计算机断层扫描 (CT) 图像进行测试，其中以 85%:15% 的比例随机分为训练集和测试集。 [40] 使用 3dMD 扫描仪进行 3D 全身扫描，使用 Tanita 生物阻抗量表测量身体成分数据，使用卷尺进行物理测量（胸部、腰部、臀部和臂围）。 [41]
3d Body Scans 3d 身体扫描
We propose a framework to automatically extract body landmarks and related measurements from 3D body scans and replace manual body shape estimation in fitting smart garments. [1] In this work, we introduce the BODY-fit dataset that contains fitted meshes of 2,675 female and 1,474 male 3D body scans. [2] The SMPL body model is based on 3D body scans and uses body shape and pose-dependent blendshapes to achieve realistic human animations [3]. [3] The Institute of Electrical and Electronics Engineers 3D Body Processing Industry Connections group is conducting a Comparative Analysis of Measurement Methods of 3D Body Scans (project details are given in Working Group Progress for IEEE P3141 Standard for 3D Body Processing, 2018-2019). [4] When people view their 3D body scans during virtual try-on, they may focus on looking at specific areas on the body depending on the garment type to be considered for purchasing during online shopping. [5] Template manikins derived from 3D body scans of the individual subjects also were used to improve accuracy. [6] Sixty-five 3D body scans of plus size women, who self-identified as size 18W, were analyzed to determine how their chest/bust, waist and hip measures compared to the top three companies’ sizing schemes. [7] In the context of 3D animation, video gaming, and virtual reality, this method, which combines body shape and pose modeling, has been developed to give motion to 3D body scans for visualization purposes. [8] This research seeks to address this critical ‘stimulus problem’ through the development of a large database of 3D body scans and body composition measurements. [9] Lumbar kinematics were concurrently measured from 3D body scans and flexible strain sensors attached to the subjects. [10] This pilot study will explore how a sample of 65 plus size women, through 3D body scans, fit into the top U. [11] It is validated on the 3DBodyTex dataset, with hundreds of high-quality 3D body scans, and shown to outperform prior works in static body pose and shape estimation, qualitatively and quantitatively. [12] In this workshop, participants learned to create a custom half-scale dress forms from 3D body scans. [13]我们提出了一个框架，可以从 3D 身体扫描中自动提取身体标志和相关测量值，并在试穿智能服装时取代手动身体形状估计。 [1] 在这项工作中，我们介绍了 BODY-fit 数据集，其中包含 2,675 名女性和 1,474 名男性 3D 身体扫描的拟合网格。 [2] SMPL 身体模型基于 3D 身体扫描，并使用身体形状和姿势相关的混合形状来实现逼真的人体动画 [3]。 [3] 电气和电子工程师协会 3D 人体加工行业连接小组正在对 3D 人体扫描的测量方法进行比较分析（项目详情参见 IEEE P3141 3D 人体加工标准工作组进展，2018-2019）。 [4] 当人们在虚拟试穿期间查看他们的 3D 身体扫描时，他们可能会专注于查看身体上的特定区域，具体取决于在线购物期间要考虑购买的服装类型。 [5] 来自个体受试者的 3D 身体扫描的模板人体模型也被用于提高准确性。 [6] 对 65 位自称为 18W 的大码女性的 3D 身体扫描进行了分析，以确定她们的胸部/胸围、腰部和臀部测量值与前三大公司的尺码方案相比如何。 [7] 在 3D 动画、视频游戏和虚拟现实的背景下，这种结合了身体形状和姿势建模的方法已被开发用于为 3D 身体扫描提供运动以用于可视化目的。 [8] 本研究旨在通过开发大型 3D 身体扫描和身体成分测量数据库来解决这一关键的“刺激问题”。 [9] 同时通过 3D 身体扫描和附在受试者身上的柔性应变传感器测量腰椎运动学。 [10] 这项试点研究将通过 3D 身体扫描，探索 65 名以上的女性样本如何适合顶级 U。 [11] 它在 3DBodyTex 数据集上进行了验证，具有数百个高质量的 3D 身体扫描，并且在定性和定量上都显示出优于静态身体姿势和形状估计的先前工作。 [12] 在本次研讨会中，参与者学会了通过 3D 身体扫描创建定制的半比例礼服形式。 [13]
Whole Body Scans 全身扫描
7 GBq) followed by post therapy whole body scans 6 days and 6 months later that didn’t show any pathological focus. [1] All of the patients with positive whole body scans due to pelvic involvement had positive early scan results. [2] Furthermore, whole body scans before and after treatment showed less focal uptake overall, suggesting fracture healing after enzyme replacement therapy. [3] This case highlights clinical proof of improvement after treatment with asfotase alfa based on increased daily step count and healing fractures on whole body scans. [4] In this work, we propose a new method that uses the combined patient attenuation/system matrix together with a tracer uptake prediction model to optimize scan times for different bed positions in whole body scans. [5] The system design incorporates a spatial beam shaper coupled with a highly sensitive flat-panel detector and very fast acquisition (<10 s) which allows for whole body scans with doses as low as 3 mGy. [6] All subjects underwent 3 consecutive whole body scans on a Hologic Horizon A DXA scanner. [7]7 GBq），然后是治疗后 6 天和 6 个月后的全身扫描，未显示任何病理灶。 [1] 所有因盆腔受累而全身扫描呈阳性的患者早期扫描结果均呈阳性。 [2] 此外，治疗前后的全身扫描显示整体局部摄取较少，表明酶替代疗法后骨折愈合。 [3] 这个案例突出了基于增加的每日步数和全身扫描愈合骨折的 asfotase alfa 治疗后改善的临床证据。 [4] 在这项工作中，我们提出了一种新方法，该方法使用组合的患者衰减/系统矩阵以及示踪剂摄取预测模型来优化全身扫描中不同床位的扫描时间。 [5] 该系统设计结合了空间光束整形器与高灵敏度平板探测器和非常快速的采集（<10 秒），允许以低至 3 mGy 的剂量进行全身扫描。 [6] nan [7]
