Three-dimensional (3D) morphological information of Zebrafish larvae is important for investigating the development of the vertebrate model. Some existing automated handling systems have already been developed to reconstruct 3D models of micro-objects, but many commercial devices are generally costly and complicated to assemble, which limits their wide usage. In this paper, we present an automated...
The key imaging parameter of number of diffusion gradient directions (NDGDs) in the protocol of diffusion tensor imaging (DTI) is significant in the acquisition of raw data. Up to date, the selection of NDGD in DTI is still in controversy for the optimized NDGD to observe 3D deterministic and probabilistic fiber trackings (FTs) of DTI in clinical evaluations. In this study, we evaluate the NDGDs of...
In this paper, we proposed an ultrafast 3-D imaging system based on phase-shifting method and a hybrid dispersion scanning technique. The imaging system is capable of acquiring the 3-D shape of the object at an ultrafast scan rate. A theoretical model is built to describe the operation principle of the imaging system and to analyze the performance of the system. In the demonstration, the imaging system...
MR diffusion tensor imaging fiber tracking (DTI-FT) could lead to false propagation because of image noise and low resolution of DTI. A variety of fiber clustering (FC) approaches have been used to refine the tract configuration. The measure of fiber similarity metric is vital in the FC algorithms. In this paper, two most common used fiber similarity metrics were compared. We firstly reconstructed...
