ON THE RELATIONSHIP BETWEEN NYQUIST RATE AND HEALTHCARE: SILICON SYSTEMS
TO CLOSE THE SUB-SAMPLING GAP IN HEALTH SCREENING AND MONITORING
Prof. Amin Arbabian
Department of Electrical Engineering
Advances in healthcare technologies have mainly focused on therapeutics, interventional
procedures, and diagnostics. These treatment steps have undergone significant improvements,
leading to higher survival rates and enhancements in quality of life. Nevertheless,
current trends are unsustainable due to inefficiency in addressing specific critical
diseases and skyrocketing national healthcare costs. An important example is cancer,
where mortality rates have not seen major improvements, even with the tremendous technological
advances in diagnostic imaging tools over the last four decades.
Preventive screening and continuous monitoring have the potential to completely change the landscape in the war against cancer and other complex disease states. Today, the human body is monitored/screened infrequently, in contrast with advanced electronic systems (many of which our community designs and ships), which are routinely and frequently monitored and calibrated. At best, patients only receive annual checkups with extremely low ‘resolution.’ How do we bring new screening and monitoring technologies closer to the patients (i.e., consumers)?
This talk summarizes our collaborative work in this general space, from new directions in low-cost, portable, and semiconductor-based, RF-Ultrasound hybrid “Tricorder” imaging systems, to ultrasound-powered implantable devices that can measure, detect, and act upon local physiological changes through closed-loop neuromodulation or “electroceuticals.” I will also briefly discuss our investigation of a noninvasive method of neuromodulation based on ultrasonic excitation.
