This paper newly proposes the active strobe imager (ASI) that can visualize the dynamic behaviors of internal organ to medical doctors within Human dynamic eye sight, so that they can get a hint for detecting the location of tumors in real time during operation. The ASI is composed of a nozzle for supplying a pulsated air jet to an internal organ, a strobe(More)
This paper proposes a new non-contact impedance imager based on phase differential technique enabling an enhanced detection of the existence of a tumor in tissues. The developed sensor is composed of an air supply system and two optical fiber based distance sensors next to the air nozzle. For a periodic air pressure, two distance sensors provide us with(More)
This paper discusses a proposed Non-Contact Tumor Imager capable of detecting a lung tumor for application during Video-Assisted Thoracic Surgery (VATS); this imager is based on the phase differential technique. The developed sensor comprises an air supply system and an optical fiber-based distance sensor adjacent to the air nozzle. A removed human lung was(More)
