Never been seen before… new applications driving procedure volume
Noninvasive / minimally invasive therapy
Focused US Tumor AblationUSA Breast Cancer: 180K new cases per year
Hysterectomies: 170-300K / year for uterine fibroids
10 Sites globally are in Alpha testing of the technology
400+ patients successfully treated for Uterine Fibroid, Breast Fibroadenoma & Breast Cancer - negligible adverse events
Ablation of tumors is monitored in real time using temperature sensitive MR imaging
Business Case:> Potential patient population of 100,000+
annually.> Estimated Reimbursement rate: $7K-8K> A clinic can effectively perform 3-4
procedures/day
Why Is Digital Mammography Needed?Image Quality
• Film mammo has 20-35% missed cancers (screening)
• Film mammo has low positive predictive value
• Overexposed, underexposed films
• Film has poor contrast at skin line, chest wall
Productivity / Economic
• Film is expensive to buy, process, handle & store
• Interventional procedures
• Only one copy of film – cannot be transmitted
Film Screen Mammography Reduces Breast Cancer Mortality by 20-40%, But There is Significant Room for Improvement
