This document discusses research on terahertz imaging technology that could allow cellphones to see through walls and detect cancer. It presents information on using this technology to detect tumors through non-invasive scanning, diagnose disease via breath analysis, and reduce healthcare costs compared to current PET scan technology. The document then proposes using this imaging technology in hospital surveillance cameras to enable real-time cancer detection for patients. User personas are described for a doctor seeking more efficient and effective cancer screening, and a homemaker worried about genetic cancer risks and unable to afford current tests. Various potential brand names are considered based on key factors from the technology and user needs, with "FaSCAN" selected as an alliterative, descriptive and evocative name that emphasizes the
