PROBLEM TO BE SOLVED: To provide a chemical feeder and a CT apparatus which suppresses a chemical use amount and allows easy inspection with high through-put.SOLUTION: A chemical feeder 100 comprises: two piston drive mechanisms 130 for respectively moving forward a piston of a syringe; a main injection condition determination part 171 for determining a chemical injection condition in main injection; a test injection condition determination part 172 for determining a chemical injection condition in test injection for injecting a chemical with an amount less than that in the main injection, before performing the main injection; and a control part 161 for, creating an injection protocol according to the injection condition determined by the test injection condition determination part 172 and the main injection condition determination part 171, so that the chemical is injected by a series of operations in which the main injection is performed after passing of a preset injection intermittent time after the test injection is performed, and controlling the operation of the piston drive mechanism 130 according to the injection protocol.SELECTED DRAWING: Figure 4 |
