Volume Scans(卷扫描)研究综述
Volume Scans 卷扫描 - RESULT The absorbed doses increased at the borders of the volume scans, and dose peaks were observed there. [1] Since public volume data are scarce, we use 2D images and account for the 3-dimensional structure using a novel deep learning method which tiles the volume scans, and then adds layers that leverage the 3D structure. [2] We harmonized the nomenclature of the outer retinal layers, added the exact area of measurement to the description of volume scans, and suggested reporting device-specific features. [3] Patients and methods: Spectral Domain OCT (SD-OCT) volume scans of 48 eyes of 24 subjects with autosomal dominant RP (ADRP) were collected retrospectively at baseline and month 12. [4] Volume scans of 12×12 mm square were obtained at the same time as the OCT angiographic (OCTA) scans (Plex Elite 9000 Swept-Source OCT®, Zeiss). [5] MATERIAL AND METHODS One-volume scans were performed on a 320-row multidetector CT volume scanner using a multi-energy CT phantom. [6] Misalignment artifact at the junction of two volumes was occasionally seen in the wide-volume scans and, when present, did not impair the diagnostic quality in the majority of cases. [7] RESEARCH DESIGN AND METHODS We trained and validated two versions of a multitask convolution neural network (CNN) to classify DME (center-involved DME [CI-DME], non-CI-DME, or absence of DME) using three-dimensional (3D) volume scans and 2D B-scans, respectively. [8] Methods Imaging sessions with multiple macular, volume scans in one eye were selected for analysis from two participant groups: Group 1, 25 imaging sessions from 21 preterm infants without macular edema imaged supine in the nursery using hh-SDOCT (Leica/Bioptigen Envisu C2300, RTP, NC); Group 2, 25 imaging sessions from 25 adults imaged using tabletop Bioptigen SDOCT. [9]结果 吸收剂量在体积扫描的边界处增加,并且在那里观察到剂量峰值。 [1] 由于公共体数据稀缺,我们使用 2D 图像并使用一种新颖的深度学习方法来解释 3 维结构,该方法将体扫描平铺,然后添加利用 3D 结构的层。 [2] 我们协调了视网膜外层的命名法,将精确的测量区域添加到体积扫描的描述中,并建议报告特定于设备的功能。 [3] 患者和方法:对 24 名常染色体显性遗传 RP 受试者的 48 只眼睛进行光谱域 OCT (SD-OCT) 体积扫描 (ADRP) 在基线和第 12 个月进行回顾性收集。 [4] 在 OCT 血管造影 (OCTA) 扫描 (Plex Elite 9000 Swept-Source OCT®, Zeiss) 的同时获得 12×12 平方毫米的体积扫描。 [5] 材料与方法 使用多能量 CT 体模在 320 行多排 CT 容积扫描仪上进行单容积扫描。 [6] 在大体积扫描中偶尔会看到两个体积交界处的错位伪影,如果存在,在大多数情况下不会影响诊断质量。 [7] 研究设计和方法 我们训练并验证了多任务卷积神经网络 (CNN) 的两个版本,以使用三维 (3D ) 体积扫描和二维 B 扫描,分别。 [8] 方法 从两个参与者组中选择对一只眼睛进行多次黄斑体积扫描的成像会话进行分析:第 1 组,来自 21 名无黄斑水肿早产儿的 25 个成像会话,使用 hh-SDOCT(Leica/Bioptigen Envisu C2300, RTP,北卡罗来纳州);第 2 组,来自 25 名成年人的 25 次成像会议,使用桌面 Bioptigen SDOCT 成像。 [9]

[1] The number of HRF on spectral domain-optical coherence tomography (SD-OCT) volume scans were counted from both eyes at 30 and 90 days. [2] Purpose To assess the structure-function relationship in glaucoma using Humphrey visual field (HVF) perimetry and a three-dimensional neuroretinal rim parameter derived from spectral domain optical coherence tomography (SD-OCT) volume scans. [3] Macular volume scans on spectral-domain optical coherence tomography on enhanced depth imaging mode were performed in all eyes. [4] Purpose: To evaluate the relationship between age, race, and sex with the neuroretinal rim using high-density spectral-domain optical coherence tomography optic nerve volume scans of normal eyes. [5] Perivascular thickening was categorized as mild, moderate, or severe, based on a set of standard reference retinal thickness maps derived from representative spectral domain optical coherence tomography volume scans. [6] A total of 180 subjects (113 open-angle glaucoma, 67 normal participants) had spectral domain optical coherence tomography volume scans and RNFL thickness measurements. [7] In this observational, retrospective cross-sectional study, segmented macular spectral domain optical coherence tomography (OCT) volume scans were reviewed to investigate if this observation also holds true for anterograde trans-synaptic degeneration. [8] Precis: Three-dimensional (3D) spectral domain optical coherence tomography (OCT) volume scans of the optic nerve head (ONH) and the peripapillary area are useful in the management of glaucoma in patients with a type I or II Boston Keratoprosthesis (KPro).
