The TMS Robotic ArmThe TMS Robotic Arm is the high-tech patent product which is developed by Yingchi. It combines with NDI near infrared navigation system, intelligent machinery tracking system and TMS system. The robotic arm can place the coil above the target brain region and start treatment automatically. During the whole treatment process, the robotic arm can track the stimulation target and adjust the coil position automatically to prevent the coil deviating from the stimulation target caused by head movement.
Adopting NDI high-resolution optical camera, the accuracy of the navigation system can up to 0.25mm. Importing the individual MRI/CT into the navigation system, operator can confirm stimulation target rapidly through the intelligent segmentation, matching, fusion, three-dimensional reconstruction function of neuronavigation software. Visualized anatomical and functional MRI data of the head and brain together with the transparent coil frame model and working area of the coil at the individual makes the facilitate the TMS navigation and stimulation process.
High accuracy is extremely important on the application of computer assisted surgery （CAS）. The strong anti-jamming capacity of Polaris Spectra system and Polaris Vicra position sensor ensure the high-accuracy measured data in Rapid Impact. When the impact is too high to affect the measured accuracy, the sensor will be triggered and sound a warning.
NDI provides the customers with extra AAK(Accuracy Assessment Kit)：AAK consists of precision evaluation tools and supporting software, enabling customers assess the accuracy of the sensor rapidly and easily. AAK assesses the data in the measuring space and will output the assessment report.
Markers mounted on the trackers and pointers reflect the infrared signal transmitted by the camera. This signal is received by the camera and from this the system calculates the exact position of coil and head in space.
The TMS Robotic Arm Navigation System
The repeated positioning accuracy of robotic arm tracking system can up to 0.01mm, with the characteristics of high speed and high accuracy. The system based on the CNC control core with multiple internal six revolute joint robot algorithm, excellent software. It adapts digital communication to control the servo driver and I/O, simplify the complexity of wire and improve the capacity of resisting noise.
