Contrast-enhanced CT employs a standard uniphasic single-injection method (SIM), wherein administration is based on two parameters: the iodine administration rate (mgI/s) and the injection duration (s). However, as the SIM uses a fixed iodine administration rate, only a uniform contrast enhancement can be achieved with this method. The iodine administration rate can be increased only by increasing...
The objective of this paper is to develop a robotic weeding system for a rice field. We took the approach of moving a large number of robots around in a field, thereby preventing weed seeds from sprouting. This paper presents the developed robotic system, in particular the robot hardware and radio communication network, and verification of the system use in an actual rice field.
