摘要:
A method for generating an image of an object using a scanning system includes performing a first portion of a scan in a first scanning mode to acquire a first dataset, receiving a halt command for a conveyor within the scanning system, decelerating the conveyor to a halt based on the halt command using a conveyor controller, and, when the object is present within an examination region after the conveyor has halted, performing a second portion of the scan in a second scanning mode to acquire a second dataset. The second scanning mode is different than the first scanning mode. The method also includes reconstructing the first dataset using a first reconstruction algorithm and reconstructing the second dataset using a second reconstruction algorithm. The second reconstruction algorithm is different than the first reconstruction algorithm. The image is generated using the first reconstructed dataset and the second reconstructed dataset.

A lithium iron phosphate hierarchical structure includes a plurality of lithium iron phosphate nano sheets and has an overall spherical-shaped structure. The overall spherical-shaped structure is constructed by a plurality of lithium iron phosphate nano sheets layered together. A method for making a lithium iron phosphate hierarchical structure includes several steps. In the method, a lithium ion contained liquid solution, a ferrous ion contained liquid solution, and a phosphate ion contained liquid solution are respectively provided. A concentration of lithium ions in the lithium ion contained liquid solution is equal to or larger than 1.8 mol/L. The lithium ion contained liquid solution, the ferrous ion contained liquid solution, and the phosphate ion contained liquid solution are mixed to form a liquid mixture. The liquid mixture is heated in a sealed reactor to form the lithium iron phosphate hierarchical structure.
