The design of the iToBoS scanner places a strong emphasis on patient protection, particularly in the context of its robotic components operating in close proximity to the patient.
Several measures have been implemented to ensure safety during the scanning process.
Initially, a 3D model of the patient is created by from the 3D cameras of the vision system. This model defines a specific volume around the patient and the trajectory scheduler ensures that the robots operate outside of the designated area, thereby preventing any direct contact with the patient under normal circumstances. However, patient safety measures also account for scenarios where the patient might unexpectedly move, potentially intruding into the robot’s operational area.
In such cases, where a collision might occur, the robot is designed with impact sensitivity that triggers an immediate halt to its operation, minimizing the risk of any significant impact. Despite these precautions, a minor collision might still be inevitable. To mitigate the risk of injury from such incidents, the robot’s hood is specifically designed without sharp edges.
