Abstract

Capsule endoscopy (CE) is the first-line diagnostic modality for detecting small bowel lesions. CE is non-invasive and does not require sedation, but its movements cannot be controlled, it requires a long time for interpretation, and it has lower image quality compared to wired endoscopy. With the rapid advancement of technology, several methods to solve these problems have been developed. This article describes the ongoing developments regarding external CE locomotion using magnetic force, artificial intelligence-based interpretation, and image-enhancing technologies with the CE system.

  • Fig. 1. Image-enhancing technology for accurate identification of the lesions. The 3D reconstruction (A) and size measurements (B) by a Mirocam viewer (Miroview® MC 4000; IntroMedic Co., Ltd., Seoul, Korea).

  • Fig. 2. Super-resolution by a Mirocam viewer (Miroview® MC 4000; IntroMedic Co., Ltd., Seoul, Korea). Erosion (A) and polyp (C) were noticed by a Miroview® MC 4000. A de-noising process, depth-guided deburring process, and deep-learning algorithm were used for super-resolution. Eventually, the clarity of the superresolution images (B and D) increased over the original images (A and C).
