本文提出了一种手持式微注射器系统，使用共路扫频源光学相干断层扫描（CP-SSOCT）作为具有高精度注射深度锁定的远端传感器。为了实现实时、高精度、直观的徒手控制，系统使用图形处理单元（GPU）以高吞吐量处理过采样的OCT信号和智能定制的运动监测控制算法。通过 60 次插入和荧光素染料注射测试进行了性能评估，以显示系统如何准确地引导针并锁定到目标深度。评估测试表明，我们的系统可以在注射50nl荧光素染料时以4.12um的平均偏差误差引导注射针进入所需的深度。
This paper presents a handheld micro-injector system using common-path swept source optical coherence tomography (CP-SSOCT) as a distal sensor with highly accurate injection-depth-locking. To achieve real-time, highly precise, and intuitive freehand control, the system used graphics processing unit (GPU) to process the oversampled OCT signal with high throughput and a smart customized motion monitoring control algorithm. A performance evaluation was conducted with 60-insertions and fluorescein dye injection tests to show how accurately the system can guide the needle and lock to the target depth. The evaluation tests show our system can guide the injection needle into the desired depth with 4.12um average deviation error while injecting 50nl of fluorescein dye.
