<p>A capsule endoscope detection apparatus is used for detecting whether a capsule endoscope exists in a body, and comprises: a logic frequency dividing circuit (2), which is used for generating a fundamental wave; a fundamental wave transmitting circuit (3), which is used for transmitting the fundamental wave at a specified frequency; and a receiving detection circuit (4), which is used for receiving an electric wave at the specified frequency, determining whether a ratio of different secondary harmonic waves reaches a set threshold value, and determines that a capsule endoscope exists in the to-be-detected body if the ratio reaches the set threshold value. Also provided is a capsule endoscope detection method that comprises: the logic frequency dividing circuit (2) generating a fundamental wave, the fundamental wave transmitting circuit (3) transmitting the fundamental wave, and the receiving detection circuit (4) determining whether a capsule endoscope exists in a body by determining a ratio of different secondary harmonic waves in an electric wave that is received. The detection apparatus and the detection method are easy to operate, and have a fast detection speed and high accuracy.</p> |
