Abstract：Objective Y-axis laser positioning ruler of body Gamma knife developed by our department can help smoothly implement a patient’s treatment plan in terms of therapeutic equipment. Methods Y-axis laser positioning ruler is composed with horizontal base, graduation ruler, slide card, laser pen and scale pointer, can be easily operated. Results 38 cases of the control group were smoothly accomplished in Y-axis direction and the passing rate was 76%. For the experimental group, 50 Y-axis-direction treatment plans were all successful, representing a passing rate of 100%. Conclusion The use of Y-axis laser positioning ruler of body gamma knife prevents a situation that the treatment plan can not be realized as numerical value of Y axis is beyond feasible scope; moreover, it enhances work efficiency, shortens treatment period and guarantees safe therapy for patient.
