Renal failure patients require lifesaving hemodialysis, two to three times weekly, for a few hours each time. The dialysis machine is connected to the patient via an arteriovenous (AV) fistula on an upper limb. The fistula must remain clear and stenosis (clogging) must be avoided. PatenSee provides a contactless, machine vision-based, monitoring system constructed by hybrid illumination DLP architecture with multiple coherent light sources and a fast CMOS sensor to capture multi-modal imaging of the fistula structure’s changes, sense sub-dermal information and read blood flow data for the early detection of fistula stenosis. The technology is designed to provide a simple way to streamline the workflow in dialysis centers, improve the quality of dialysis patient care and to support the busy nursing staff. The system is adaptable for home-use as well.
Cervical cancer is the fourth most common cancer in women worldwide. In low-income countries, it is a leading cause of death. Biop Medical has developed a portable multimodal optical imaging device for early screening and detection of squamous intraepithelial lesions (SIL). The device is a non-invasive probe which scans the cervix area and combines information from multiple optical modalities, for in vivo, real time detection of SIL. In this paper we present sample data acquired from 18 participants using the device in an in-vivo pilot study and present preliminary results of classification into low-grade and high-grade SIL.
