Abstract

The invention discloses a target water quantitative distribution device for a cyclotron liquid target, and belongs to the field of nuclear medicine and molecular imaging. The device structurally comprises an accelerator end one-way n distribution valve, a quantitative end one-way n distribution valve, an injection component and a target water rotating bottle, and at least one channel of the accelerator end one-way n distribution valve is used for conveying target water generated by an accelerator into a target water rotating bottle or a hot chamber; and at least one channel of the quantitative end one-way n distribution valve is connected with the injection assembly, and at least one channel of the quantitative end one-way n distribution valve is connected with the rotating bottle in the target water and used for conveying the target water in the rotating bottle in the target water to the accelerator end one-way n distribution valve pipeline. Compared with like devices in the prior art, the target water quantitative distribution device for the cyclotron liquid target not only can realize directional and quantitative distribution of high-activity target water, but also greatly improves the use efficiency of high-value consumables such as a medical cyclotron and the target water, and overcomes the defects that the conventional high-activity target water can only be conveyed in a directional manner (1-2 hot chambers), and automatic quantitative distribution cannot be realized.
