System and method for acquiring and storing images

Abstract

The invention relates to a system and a method for acquiring and storing images. The system comprises an image acquisition device, an outer cavity device and an image processing device; the image acquisition device comprises an image sensor array unit, a storage unit, an energy unit and a control unit; the energy unit comprises a wireless switch, a cell and a wireless radio-frequency energy extracting module for extracting energy from radio-frequency energy signals; by receiving the radio-frequency energy signals and command signals sent by the outer cavity device, the control unit controls cell power supply through the wireless switch according to the command signals when an image sensor is placed in a cavity to carry out acquisition and storage of image data, controls power supply of the wireless radio-frequency energy extracting module through the wireless switch and sends the stored image data to the outer cavity device when the image acquisition device is moved out of the cavity; the outer cavity device receives the image data transmitted by the image acquisition device and stores or transmits the image data. The system and the method reduce power consumption to great degrees, are applicable to image acquisition in a biological cavity, and can realize full-view image acquisition.

Description

technical field [0001] The invention relates to the field of intracavitary inspection of medical patients, in particular to an image acquisition and storage system and method suitable for full-view inspection of body cavity organs of living organisms, especially digestive tract organs.

[0002] Endoscopic examination technology is currently the most effective means of examination for digestive tract diseases. The original conventional endoscopic examination technology is equipped with guiding intubation, which not only brings a lot of inconvenience to the system operation, but also brings great inconvenience to the patients. At the same time, due to the use of wired transmission, the site of conventional endoscopic examination is also limited, and the inspection of the small intestine cannot be realized.

With the development of microelectronic technology and MEMS technology, an oral endoscope system has emerged, which solves the problem of endoscopic examination of the blind area of ​​the small intestine, but the existing clinical oral endoscope products only use one or two The driving force of this camera equipment mainly depends on the peristalsis of the digestive tract, and the frame rate of image acquisition is generally 2 frames per second. In addition, the system requires the patient to wear a wireless receiving device during the digestive tract examination, which limits the daily activities of the patient, and because the external receiving device has multiple antennas that need to be checked It needs to be operated by professionals before it is placed on the designated part of the patient, and it also brings discomfort to the patient. At the same time, the existence of multiple antennas also leads to an increase in the instability of the system, and the oral internal view using wireless data transmission technology The mirror also has the problem of receiving sensitivity, which affects the quality of the received image

In the applied Chinese invention patent (application number 200810055863.3), a spherical oral endoscope with multiple cameras is proposed. Transmit electromagnetic wave signals modulated with image data. At this time, the energy consumed by the battery for wireless communication will account for at least 60% of the energy consumed by the entire device. Due to the limited power supply capacity of the existing battery, the image acquisition device cannot be realized when it is powered by a battery. For the inspection of the whole digestive tract, if the method of using radio frequency to supply energy from the outside of the body cavity to the device inside the body cavity can prolong the working time of the image acquisition device, it will greatly increase the workload of the operator, and because the radio frequency energy radiation device outside the body will also Increasing the patient's carrying weight restricts the patient's activities and increases discomfort, and strong electromagnetic radiation will also have a certain impact on human health

In the published Chinese invention patent CN101084822A, a control method of a capsule endoscope with a memory storage device is proposed, but the capsule endoscope involved in this patent needs to be cleaned and disinfected after being discharged from the human body, and then the capsule shell is cut open body, and then take out the electronic device and connect it to the terminal host to read the image data. The actual operation is more complicated, especially when taking out the electronic device in the capsule, you must be very careful to ensure that the electronic device is not damaged. In addition, the capsule endoscope involved in this patent cannot Realize image acquisition from all angles of view
