GE Healthcare 1.5 T MRI (EMC/UH)
GE’s 1.5T MRI systems provide provides high-quality soft-tissue–contrast imaging to support advanced radiation therapy planning. Having MR-simulators directly within the department streamlines the clinical workflow, reducing scheduling complexity, minimizing patient transport, and enabling tighter coordination between simulation, contouring, and planning teams. Importantly, patients can be also easily be simulated in their treatment immobilization, ensuring accurate geometric consistency between imaging and delivery.
BK Medical Ultrasound (All Sites)
BK Ultrasound systems provide high-resolution, real-time ultrasound imaging to support image-guided brachytherapy procedures. Ultrasound is primarily used for treatment guidance during skin and prostate brachytherapy, where real-time visualization is critical for accurate applicator or needle placement, target localization, and assessment of surrounding anatomy.
Other Treatment Planning & Quality Assurance Software
Suncheck (SNC)
SunCHECK by Sun Nuclear is a comprehensive quality management platform for radiation therapy, built on a centralized dashboard and cloud-enabled architecture. We use SunCHECK to perform, document, and track daily, monthly, annual, and post-service quality assurance (QA) across nearly all treatment machines at all of our clinics. This unified system supports standardized QA workflows, improves consistency and traceability, and enables efficient oversight of machine performance and compliance across our multi-site network.
