## 5 Conclusions  
The edgeless diode array displayed excellent linearity and exhibited sensitivities across the array with reproducibility of 0.33%. The 2D edgeless array's measurements of PDDs closely match with the experimental output of the ion chambers for depths ranging from d\({}_{\text{max}}\) to 20 cm, with a discrepancy of only 1.4%. A minor systematic under-response at increased depths was linked to a dependency on DPP. The 2D edgeless array's output factor corresponds closely with the IC and EBT3 film responses, within 3.6% differences across field sizes from 0.5 to 20 cm. The DPP response only varied by \(\pm\)2% within the 0.12 to 0.39 mGy/pulse range, indicating the nearly complete dose rate independence of the pre-irradiated silicon edgeless array. Notably, at dose rates below 0.1 mGy/pulse, a decrease of 15% was observed. The edgeless array dose angle dependence remains within 2% for most of the irradiated angles ranging from 0\({}^{\circ}\) to 180\({}^{\circ}\); however, a maximum angular dependency of 4% (without post-processing or correction factors) was observed for angles close to 90\({}^{\circ}\). While adjustments are necessary to meet the dose tolerances of SRS, these corrections could enable angular independence even for lateral irradiations, which is not currently achievable with commercial devices.  
Overall, the edgeless array proved to be a promising choice for correction-free, angularly independent relative dosimetry under stereotactic radiosurgery conditions. To mitigate dose-per-pulse dependency, lower resistivity diodes could be employed with the minority carrier lifetime reduced with pre-irradiation.  
Further studies are needed to validate the reliability of the array as a patient-specific quality assurance measurement tool for non-coplanar delivery systems such as the Gamma Knife(r) or CyberKnife(r).
