Data Transfer Implementation in the Wireless Capsule Endoscopy

摘要

The wireless capsule endoscopy is a modern mean for an invasive.examination of the digestive tract. This paper deals with the features of the information transfer implementation between the wireless capsule and the receiver, which are the part of the "Landish" capsule endoscopic complex. The benefits and the shortcomings of usinguni- and bidirectional communication in the capsule are discussed, a reasonable choice in favor of the unidirectional communication is made. The various options of the integrity control and the recovery are analyzed and experimentally verified. For reasoning the choice between the noiseless coding and the use of the checksum we carried out an experiment on influence of their implementation on the energy consumption of the endoscopic capsule. It was found that the noiseless coding considerably reduced the time of an autonomous work of the capsule that is why the checksum was selected.
