IMI
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.
