System and method for wireless image acquisition in biological body cavity

Abstract

The invention discloses a system for wirelessly acquiring an image in organism cavity, comprising an image acquiring device, an image receiving device and a floor, wherein the floor is arranged below a measured organism and used for emitting alternating electromagnetic energy to the space above the floor; the image receiving device wraps the measured organism and is used for enhancing the alternating electromagnetic field strength in the organism region and receiving and storing the image sent by the image acquiring device; and the image acquiring device is arranged in the organism cavity and used for receiving the alternating electromagnetic energy and acquiring the image in the organism cavity and sending the acquired image to the image receiving device. By utilizing the system and the method for wirelessly acquiring the image in the organism cavity, the electric quantity supply of the image acquiring device can be guaranteed; the image acquiring frame rate can be enhanced to reduce the missing rate; the image resolution ratio can be enhanced; the working time is prolonged; the image acquisition in a whole digestive tract can be realized; and no wire connection exists between the floor and the image acquiring device so that the mobility of the measured organism in the image acquiring process is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical endoscopes, in particular to a wireless image acquisition system and method in a biological body cavity. Background technique [0002] Gastrointestinal diseases infest countless patients around the world. At present, endoscopy is the most commonly used and most direct and effective way to check for this disease. Therefore, endoscopy system plays an extremely important role in the diagnosis of gastrointestinal diseases. Existing commonly used endoscopic systems and the transmission of endoscopic images are all completed by wires, and these systems have to be equipped with guiding intubation tubes, which not only brings a lot of inconvenience to the operation of the system, but also makes it difficult for people to undergo inspection. The patients brought a lot of discomfort and pain, and because of the cable transmission, the parts that can be inspected by the endoscope are also limited, such as th...

Problems solved by technology

Existing commonly used endoscopic systems and the transmission of endoscopic images are all completed by wires, and these systems have to be equipped with guiding intubation tubes, which not only brings a lot of inconvenience to the operation of the system, but also makes it difficult for people to undergo inspection. The patients brought a lot of discomfort and pain, and because of the cable transmission, the parts that can be inspected by the endoscope are limited, such as the inspection of the small intestine, etc.

With the development of microelectronics technology, a wireless endoscope system has emerged, which solves the above-mentioned endoscopic inspection problem in the blind area of ​​the small intestine. The power of the battery is limited, and generally only a relatively small (for example, 2 frames per second) image acquisition frame rate is used for image acquisition. The phenomenon of part image omission will be more serious

In addition, due to the limited battery power, the existing wireless endoscopy system generally chooses a lower image resolution to save power, and it is difficult to achieve image acquisition of the entire digestive tract

[0003] To sum up, the existing wireless intravital image acquisition system is limited by the limited power of the battery, resulting in low image acquisition frame rate, serious missed detection, low image resolution, and short working time, making it difficult to realize the whole digestive system.
