 top of conventional B-mode ultrasound. Note that in comparison to ultrasound, photoacoustic imaging systems inherently lack the ability to image the tissue anatomy and essentially only image the vasculature (i.e., blood, which is a strong absorber of light). For PAT systems, there is no clinical trial data available (to our knowledge) and no PAT systems have been approved for clinical use. For PAI systems, the Imagio Breast Imaging has been used in clinical trials and is FDA cleared to be used as an adjunct to conventional handheld breast ultrasound.

All of these technologies face challenges to expansion, including FDA clearances and insurance reimbursement. However, the shortcomings of other imaging methods such as ionized radiation exposure, high costs and deployment challenges of MRI, and the inefficiency of mammography in detection of cancer in women with dense breasts, are sufficiently compelling for industry to address these obstacles, and these shortcomings will continue to create an opportunity for development and commercialization of advanced screening systems such as the Company’s.

To our knowledge at the time of filing this registration statement/prospectus, we are not aware of any technologies approved for primary screening clearance by the FDA except for various types of technology related to X-ray mammography.

#### Future Market Opportunities
While the Company’s short-to-medium term focus will be on breast scanning, future products will open additional markets. The Company’s Open Partial Angle Scanner concept, which is currently under development, is expected to provide entry into the global orthopedic medical imaging market, which is estimated to be $7.3 billion by 2025 12 .

10 Medical reflection transducer, also known as an ultrasound transducer, is a device that converts electrical energy into sound waves, and the back again into electrical energy. It is used in medical imaging to produce images of internal organs and tissues in the body, and it is used in various medical imaging techniques such as ultrasound, echocardiography and Doppler imaging.

11 Breast vasculature refers to the blood vessels that supply and drain blood from the breast tissue. The breast is a highly vascularized organ, and the blood supply comes from
