Spectral CT 7500 RT
Target with spectral certainty
Take the next big leap in radiation oncology treatment planning
Target with spectral certainty to enhance accuracy in radiation oncology planning. For the first time, you can have spectral insights and true conventional results in a single scan, on a spectral-detector CT system designed specifically for radiation oncology. Philips Spectral CT 7500 RT promotes accuracy in planning while fitting right into your current radiation oncology workflow so you can continue to enhance patient care.
Experience proven spectral accuracy
Use spectral CT results, such as electron density and effective atomic number, for RT planning to enhance visibility for tumor delineation.
Scan as you normally would
Acquire high-quality true conventional CT images and spectral results in a single scan, with easy workflow and without special protocols.
See accuracy in dose calculation
Spectral CT has been shown to reduce proton SPR error by more than 50% compared to conventional CT, resulting in a mean error below 1%.1
Potentially save time and costs
A single spectral scan could help avoid the need for multiple CT scans, as well as scans from other modalities, throughout the treatment cycle.
Discover world-first capabilities for your RT planning
Every RadOnc team knows that cancer is becoming increasingly complex
The challenges faced in radiation oncology are significant. Not only are the number of cancer cases rising, but it's becoming increasingly complex to characterize, sub-type and stage tumors. Targeting with spectral certainty means spectral accuracy in planning.
Spectral accuracy in RT planning
See delineation certainty, with improved visualization and assessment of tumors and organs at risk. Enhance accuracy in photon and proton dose calculation through the stopping-power ratio (SPR) map and direct electron density (ED) results. Quantitatively assess physiologically active tumor regions.
Easy radiation oncology workflow
Always on spectral offers layers of rich spectral results – on demand and with no special protocols. A single dual energy scan with true conventional CT and spectral CT results also potentially minimizes the need for additional imaging modalities.
80 cm extended field of view (EFOV)
The extended field of view of up to 80 cm enables complete visualization of the patient’s anatomy and provides a high level of Hounsfield Units (HU) accuracy.2
Advanced RadOnc capabilities
Perform spectral respiratory gated scans with Spectral CT 7500 RT, the world’s-first spectral 4D CT.
High-performance table for positional accuracy
Spectral CT 7500 RT complies with AAPM-TG-66 and features an indexed therapy top to allow for positional accuracy in CT sim and treatment.
Multimodality Simulation Workspace
Spectral CT 7500 RT is compatible with Multimodality Simulation Workspace (MM SIM3), a multi-modality image platform that supports the conversion of ED and Z-effective spectral results into stopping-power ratio (SPR) maps.
Compatible with leading third-party solutions for streamlined treatment workflows
Spectral CT 7500 RT enables streamlined workflow with treatment solutions, including respiratory gated systems and lasers for consistency and ease of use throughout the workflow from simulation to treatment.
Spectral CT can reduce the uncertainty margins during treatment planning.
