Simultaneous Multi-plane Imaging of Neural Circuits
Recording the activity of large populations of neurons is an important step toward understanding the emergent function of neural circuits. Here we present a simple holographic method to simultaneously perform two-photon calcium imaging of neuronal populations across multiple areas and layers of mouse cortex in vivo. We use prior knowledge of neuronal locations, activity sparsity, and a constrai...
متن کاملHigh Resolution 3D Multi-slab Multi-shot Spin Echo Diffusion-Weighted Imaging
Introduction: The need to detect small brain lesions and to reduce partial volume effects in fiber tractography has made high resolution isotropic 3D diffusion-weighted imaging (DWI) a research focus in diffusion acquisition methodology [1-4]. To achieve reasonable scan time, most of the proposed 3D DWI methods used steady-state free precession (SSFP) acquisition [1-3] which has a complicated d...
متن کاملMulti-beamforming for 3D ultrasonic imaging
This work describes the development of a new 3D ultrasonic imaging method that combines different beamforming techniques (Phased Array -PAand Synthetic Aperture Focusing Technique -SAFT-). The proposed methodology uses a silicone mask along the x-axis to produce a wide beam in the array width direction (y-axis). Then, a coherent-spatial composition of several phased array B-scan images is imple...
متن کاملEfficient Multi-resolution Plane Segmentation of 3D Point Clouds
We present an efficient multi-resolution approach to segment a 3D point cloud into planar components. In order to gain efficiency, we process large point clouds iteratively from coarse to fine 3D resolutions: At each resolution, we rapidly extract surface normals to describe surface elements (surfels). We group surfels that cannot be associated with planes from coarser resolutions into coplanar...
متن کاملCreating effective focus cues in multi-plane 3D displays
Focus cues are incorrect in conventional stereoscopic displays. This causes a dissociation of vergence and accommodation, which leads to visual fatigue and perceptual distortions. Multi-plane displays can minimize these problems by creating nearly correct focus cues. But to create the appearance of continuous depth in a multi-plane display, one needs to use depth-weighted blending: i.e., distri...
