Area of Science:

Medical Physics
Radiation Oncology
Radiosurgery Technology

Background:

Single isocenter techniques reduce radiosurgery delivery times for multiple targets.
Conventional Winston-Lutz tests are unsuitable for multitarget radiosurgery when targets are not at the isocenter.

Purpose of the Study:

To describe and validate a novel multi-target test (MTT) for accurate patient positioning in radiosurgery.
To provide a quality assurance tool for multitarget radiosurgery workflows.

Main Methods:

A phantom with three spheres was scanned using high-resolution CT.
Custom software determined optimal beam and aperture parameters for centering spheres.
The phantom was repositioned using a robotic couch, and MV EPID images verified sphere centering within apertures.

Main Results:

Calculated maximum distance between sphere and aperture center was 0.07 mm.
Median differences measured from MV images ranged from 0.1 mm to 1.4 mm, with a median of 0.8 mm.
The test demonstrated feasibility with selected beam angles and aperture configurations.

Conclusions:

The multi-target test (MTT) is a practical end-to-end quality assurance solution.
It effectively verifies the entire positioning process in multitarget radiosurgery.
The MTT ensures accuracy from CT scanning through to beam delivery.
