System And Methods For Detecting Foreign Objects After Surgery
Patent Number: WO 2005/044085 A1
Date Filed: May 19, 2005
Country Filed In: WIPO
Product Application: Zero-Count Detector
Description:
A radar system uses an array of transceivers combined with signal processing techniques to provide a new type of medical imaging technology. The system detects foreign objects such as sponges, surgical tools, etc., based on the difference in the electrical properties between biological tissue and the foreign object. Advantageously, synthetic aperture radar (SAR) techniques are coupled with statistical filtering algorithms to detect, locate, and optionally also identify a foreign object.
Field of Use: The Zero-Count Detector was a novel device that would allow a physician to be able scan a patient pre- and post-op to be able to accurately and quickly detect the presence of any foreign materials in the operation area of the patient. The device was designed to address the almost $8 billion dollars in loss the medical industry faces when objects such as clamps, sponges, gauze, and other materials used in a surgical procedure are inadvertently left inside a patient after surgery. This was the first technology that Josh developed that leveraged his acumen in rider-guidance for a medical device technology.
