Elekta – IMPAC Medical Systems Inc

Elekta IMPAC Medical Systems provides specialized oncology information systems designed primarily for radiation oncology departments, cancer centers, and comprehensive oncology practices. Originally founded as IMPAC Medical Systems in 1972 and acquired by Elekta in 2005, the company has established itself as a leading provider of radiation oncology software worldwide.

The MOSAIQ platform represents Elekta's flagship oncology information system, offering an integrated suite for managing radiation oncology, medical oncology, and particle therapy workflows. The system is specifically engineered to handle the complex documentation requirements of cancer treatment, including treatment planning integration, linear accelerator connectivity, dose tracking, and regulatory compliance for radiation therapy protocols. MOSAIQ serves as both an oncology-specific EMR and a comprehensive oncology practice management system.

The platform's primary differentiator is its deep integration with radiation therapy equipment and treatment planning systems. Unlike general ambulatory EMR systems that may offer oncology modules, IMPAC's solutions are purpose-built for the unique needs of radiation oncology workflows, including DICOM RT support, treatment verification, quality assurance documentation, and physics calculations. The system connects directly to treatment delivery devices, particularly Elekta's own linear accelerators and other radiation therapy equipment.

Elekta IMPAC primarily targets medium to large oncology practices, hospital-based cancer centers, academic medical centers with radiation oncology departments, and comprehensive cancer treatment facilities. The deployment model typically involves on-premises enterprise installations, though cloud-hosted options have become available in recent years. Implementation complexity is significant due to the specialized nature of radiation oncology equipment integration.

The system serves a global customer base with installations in over 60 countries, making it one of the most widely deployed radiation oncology information systems worldwide. Key strengths include strong treatment planning integration, comprehensive radiation therapy workflow support, multi-modality treatment tracking, and extensive quality assurance tools. The platform is designed to meet stringent radiation oncology regulatory requirements including those from the American College of Radiology and various international regulatory bodies.

While IMPAC offers general ambulatory EMR capabilities for oncology practices, its core value proposition centers on radiation oncology departments requiring sophisticated treatment planning integration and device connectivity. The system competes primarily with Varian's ARIA oncology information system rather than traditional ambulatory EMR vendors.
