Description

technical field [0001] The invention relates to the technical field of electrical impedance imaging, in particular to an electrical impedance pulmonary function imaging robotic arm. Background technique [0002] Electrical Impedance Tomography (EIT) is a new direction of medical imaging technology. Its basic principle is that different tissues in the human body have different resistance / conductivity under different physiological and pathological states. The human body applies a small safe driving current / voltage, and through the measured response information of the driving current or voltage in the human body, the image of the resistivity distribution or its change inside the human body is reconstructed. [0003] Because the electrical impedance imaging technology is to place multiple electrodes in a certain arrangement to ensure the imaging quality, the electrode placement of different test targets must conform to a unified pattern, so if the electrodes are directly placed ...

AI Technical Summary

Problems solved by technology

[0003] Since the electrical impedance imaging technology is to place multiple electrodes in a certain arrangement to ensure the quality of the image, the placement of electrodes for different test targets must conform to a uniform pattern, so if the electrodes are directly placed on the surface of the test target by the operator, it is very difficult Difficulty in ensuring electrode arrangement consistent with pre-planned patterns, uniformity and consistency across different test targets, negatively impacting image quality and requiring significant time-consuming draining of electrodes before each test

[0004] Most of the existing electrical impedance imaging adopts the idea that the electrodes are attached to the chest skin surface of the patient to be tested, and the arrangement of the electrodes needs to conform to the arrangement rules, which increases the time and difficulty of electrode arrangement, and when the electrodes do not contact the patient's skin or have a gap It will affect the imaging effect and diagnostic results of the electrical impedance imaging system
