Abstract

A chemical liquid injector that can easily set various injection conditions according to a region and an objective to be imaged. The chemical liquid injector includes two piston driving mechanisms for operating syringes filled with a first chemical liquid and a second chemical liquid, respectively, an input unit for receiving an input of a data, and an injection control unit for controlling an operation of the piston driving mechanisms. The injection control unit is set with a multistage injection mode in which injection operations are performed in a plurality of injection phases. In the multistage injection mode, the injection control unit is configured to receive the input of the mixing rate of the first chemical liquid and the second chemical liquid for each of the plurality of injection phases, set injection conditions of the first chemical liquid and the second chemical liquid so that the first chemical liquid and the second chemical liquid are injected at the received mixing rate, and control the operation of the driving mechanisms according to the set injection condition.
