Description
<p> The capsule endoscope has the advantage that cameras mounted inside the capsule can examine the digestive tract from the mouth to the anus only by swallowing, and the burden on the patient is small. However, the exact position of the capsule endoscope in the body is unclear. Therefore, authors have produced a real-time position detector that detects the position of the capsule endoscope in the body based on the pitch of the speaker sound.</p><p>The manufactured position detector had low accuracy of position detection, so authors improved the directivity of the antenna by attaching a shield to the antenna of the position detector. As a result of experiments using human simu-lated substances, the position detector with shield has a 83% reduction in position detection error range compared to the position detector without shield.</p>
