Accuracy versus Repeatability Repeatable It’s up to you to make the right choice – for your patients‘ sake! A robot has different metrology or measurable characteristics, that will have a direct impact on the effectiveness of the robot during the execution of its foreseen tasks. The main measurable characteristics are repeatability and accuracy. Depending on the application, it is of highest importance to clearly understand the meaning and especially the difference of these characteristics. Repeatability is doing the same task over and over again, while accuracy is hitting your target each time. Especially when it comes to tumor treatment and patient health it is significant to understand which criteria of a robot really matter. With our explanations below you will be able to learn about the differences and judge the perfect fit of a patient positioning system. Misidentifying those terms leads to misinterpretation when reviewing a product specification and could lead to unsatisfying results in the operating system during treatment. With a correct understanding you can be sure to make the right choice for a patient positioning system and last but not least to secure treatment success for your patients.

Pose repeatability › Absolute accuracy without payload variation › The pose repeatability represents the ability of the robot to The absolute accuracy without payload variation represents always return to the same programmed position from the the ability of the robot to move to a not pre-programmed same direction, or in simple words, the robot is starting at the position from any starting point and measures how close the programmed point A and going to the programmed point B achieved position is to the desired target position while the and those points are never changing. The pose repeatability...
