Ask Questions of this Manuscript:
What is the background behind your study?
Patient setup can be challenging for eccentric brain targets.
What is the purpose of your study?
For the treatment of far-anterior and far-posterior field targets, the L-shape Y/Z slides were developed.
Describe your patient group.
Describe what you did.
The L-shape Y/Z slides are precision instruments for the treatment of far-anterior and far-posterior field lesions that cannot be reached with the standard Y/Z slides (Elekta). The actually available space within the Leksell coordinate frame model G includes any points with the coordinates of X= 10~190mm and Y= -10~210mm.
Describe your main findings.
In the standard Y/Z slides with stereotactic frame, the physically possible maximum y-axis range of treatment in the trunnion mode permits the coordinates of 25 to 175mm. The L-shape Y/Z slides are used for y-coordinates of -10 to 210mm. The material used for the L-shape Y/Z slides is lightweight aluminum.
Describe the main limitation of this study.
This was a limited test of functionality.
Describe your main conclusion.
The L-shape Y/Z slides used for gamma knife radiosurgery are a new design that can increase the range of y-axis.
Describe the importance of your findings and how they can be used by others.
These slides are easy to use, and are as safe as the standard Y/Z slides for the treatment.
