Figure 2: Dose distribution around Novoste Beta-Cath 3.5F 90 Sr 90 Y device, which was placed over the OCT device in the novel dose calculation software, calculated for a) a water phantom and b) patient-specific dosimetry.

Conclusion:

Our software is the first to allow for accurate, patient-specific dose calculations on OCT images for intravascular brachytherapy. We have shown that inadequate dose is delivered to a lesion area with water-based treatment planning. Our software can serve as a decision-making tool for clinicians to make informed decisions on risk stratification and follow-up strategies for in-stent restenosis patients.
