心血管介入虚拟手术造影剂显影仿真

Virtual Surgery Contrast Development Simulation with Cardiovascular Intervention

心血管介入手术造影剂的使用对肾功能尤其对肾功能不全患者影响较大。在使用心血管介入手术模拟器进行手术培训过程中,造影剂剂量信号的检测是造影剂模拟的关键技术之一。将光学位移传感器用于造影剂注射剂量信号检测,并成功应用于心血管介入手术模拟器。通过Windows API提取光学位移传感器位移信息,并进行实验验证基于光学位移传感器的造影剂注射剂量信号检测的可行性。

The contrast agent used in cardiovascular interventional operation has advene effects on renal function,especially for the renal inadequacy patients.In the use of cardiovascular interventional operation simulator for operation training,detection of contrast agent signal has become one of the key techniques of contrast agent simulation.This paper presents the signal detection of contrast agent dose by using optical displacement sensor,and the successful application to cardiovascular interventional operation simulator.The installation box of sensor is manufactured by using 3D printing technology,the displacement information of optical displacement sensor is extracted by windows API,and experiments are conducted to verify the feasibility of contrast agent signal detection based on optical displacement sensor.
