With the continuous development of medical technology, the functions of CT systems are increasing, the size of CT machines is constantly expanding, and the size of antennas is also becoming larger and more diverse. In addition, traditional antennas take up a lot of space during transportation and are difficult to repair once damaged. Therefore, it is necessary to improve the existing antennas for CT machines.
