An electromechanical device is described which automatically injects the radiotracer bolus used in the measurement of cerebral blood flow. It consists of two electronically controlled, solenoid operated syringes, one containing the radiotracer solution and the other heparinized saline. Results are presented which show that use of the automatic bolus injector in place of hand injection leads to an improvement in the precision of measured flow values. Additional advantages of the device are discussed.
本文描述了一种机电装置，该装置可自动注射用于测量脑血流量的放射性示踪剂团注。它由两个电控、电磁阀操作的注射器组成，一个装有放射性示踪剂溶液，另一个装有肝素化盐水。给出的结果表明，使用自动团注注射器代替手动注射可提高测量血流值的精度。文中还讨论了该装置的其他优点。
