Summary
A new phantom accurately checks stereotactic computed tomography localization systems. This tool achieves sub-millimeter accuracy, enhancing precision for stereotactic radiosurgery.
Area of Science:
- Medical Physics
- Radiosurgery Technology
Background:
- Accurate localization is critical for effective stereotactic radiosurgery.
- Existing methods for verifying computed tomography (CT) localization systems can be complex.
Purpose of the Study:
- To develop and evaluate an easy-to-use phantom for assessing stereotactic CT localization accuracy.
- To validate the phantom's performance on a commercial stereotactic radiosurgery system.
Main Methods:
- Construction of a novel, user-friendly phantom.
- Localization of the phantom's reference point using a precision measuring implement.
- Verification of localization accuracy with a computed tomography (CT) scanner.
Main Results:
- The phantom was successfully implemented on a commercial stereotactic radiosurgery system.
- Localization accuracy was determined with a standard deviation of less than 0.3 mm in three orthogonal axes.
Conclusions:
- The developed phantom provides a reliable and accurate method for checking stereotactic CT localization systems.
- This tool enhances the precision and safety of image-guided radiosurgery procedures.
