BACKGROUND New ablation strategies for atrial fibrillation or nonidiopathic ventricular tachycardia are increasingly based on anatomic consideration and require the placement of ablation lesions at the correct anatomic locations. This study sought to evaluate the accuracy of the first clinically available image integration system for catheter ablation on 3-dimensional (3D) computed tomography (...

Machine vision for plant phenotyping is an emerging research area for producing high throughput in agriculture and crop science applications. Since 2D based approaches have their inherent limitations, 3D plant analysis is becoming state of the art for current phenotyping technologies. We present an automated system for analyzing plant growth in indoor conditions. A gantry robot system is used t...

purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...

purpose: to evaluate changes in anterior chamber (ac) parameters before and one month after nd:yag capsulotomy. methods: a total of 30 eyes from 27 patients with posterior capsule opacification graded 2-4 with surgical history of uneventful phacoemulsification and acrylic foldable iol implantation were included in this study. before capsulotomy and one month later, anterior chamber depth, volum...

AIMS The planimetry method using three-dimensional (3D) echocardiography is useful for providing an accurate mitral annulus area (MAA) value. However, this method is relatively unavailable. Therefore, we evaluated the accuracy of conventional methods for MAA measurement compared with that of 3D planimetry. METHODS AND RESULTS Two-dimensional (2D) and 3D transoesophageal echocardiography (TEE)...

We present a novel microfluidic platform to examine biological assemblies at high-resolution. We have engineered a functionalized chamber that serves as a ‘‘nanoscale biosphere’’ to capture and maintain rotavirus double-layered particles (DLPs) in a liquid environment. The chamber can be inserted into the column of a transmission electron microscope while being completely isolated from the vacu...

Volumetric three-dimensional displays offer spatially accurate representations of images with a 360° view, but have been difficult to implement due to complex fabrication requirements. Herein, a chemically enabled volumetric 3D digital light photoactivatable dye display (3D Light PAD) is reported. The operating principle relies on photoactivatable dyes that become reversibly fluorescent upon il...
