Summary: Philips’ Spectral CT 7500 RT, now FDA-cleared, enhances tumor visualization and tissue characterization for radiation therapy, improving targeting precision and reducing healthy tissue damage while streamlining radiotherapy workflows.

Key Takeaways:

  • Spectral CT 7500 RT offers precise tumor targeting with enhanced tissue characterization, improving patient-specific radiotherapy.
  • The scanner provides both conventional and spectral CT in a single scan, increasing accuracy while minimizing healthy tissue damage.

Royal Philips received 510(k) clearance from the U.S.FDA for its Philips Spectral CT 7500 RT, a new detector-based spectral CT solution for radiation therapy..

Enhanced Tumor Visualization

The Philips Spectral CT 7500 RT integrates the unique tumor visualization and tissue characterization capabilities of spectral CT into cancer treatment and planning. Radiation oncologists can precisely target radiation therapy to the specific physiological characteristics of a patient’s tumor, minimizing damage to healthy surrounding tissue and reducing potential unwanted side effects.

The radiation therapy CT scanner offers respiratory-gated spectral imaging, giving radiation oncologists all the benefits of 4D conventional CT and the enhanced visualization and quantification of spectral CT. This innovation can benefit radiotherapy departments by reducing costs of additional scans, enhancing accuracy, and enabling more effective treatment plans for more cancer patients.

Precision in Radiation Treatment Planning

“Tumor delineation, beam attenuation, and respiratory motion are critical factors in radiotherapy planning. The spectral information provided by Spectral CT 7500 RT enhances tissue characterization, enabling wider access to highly personalized and precisely targeted treatment for more patients without adding extra steps to current radiotherapy workflows,” says Dan Xu, global business leader of CT at Philips.

Spectral CT has been shown to reduce proton stopping-power ratio (SPR) error by more than 50% compared to conventional CT, improving the accuracy of radiation treatment and sparing healthy tissue, according to the company. Philips Spectral CT 7500 RT acquires both true conventional CT and spectral CT information in a single scan. It can automatically create the SPR map and direct electron density results to enhance both dose calculation and accuracy of radiotherapy planning.
