This system eliminates the need for CT or x-ray imaging.

Rhino-sinusitis, or sinus infection, is an inflammation of the paranasal sinuses, which can be caused by different conditions (bacterial, fungal, viral, allergic, or autoimmune). Bacterial rhino-sinusitis is currently assessed by puncture or imaging techniques (x-ray or CT) in order to detect the presence of an air-fluid level within the paranasal sinuses. The absence of this level is significant enough to rule out bacterial infection. The system presented in this innovation provides a reliable, non-invasive, and low-cost procedure to evaluate the presence of fluid inside the paranasal sinuses by means of an ultrasound scan.
