Marginator Positron CameraIMI is developing the Marginator Beta Camera (Positron Camera) to improve cancer surgery by evaluating surgical margins for remaining amounts of cancer tissue after tumor excision.

The first application will be for breast cancer. An unmet need exists because:
- 30-40% of lumpectomies fail to achieve negative margins
- Of breast tumors that recur, 70% recur at primary tumor site.

The Marginator Beta (Positron) Camera Features:

Produces color image

  • 2 mm resolution
  • Able to detect 4 mg of cancer
  • 1 minute acquisition time
  • 15 mm FOV

For Investigational Use Only
