Analysis on Electromagnetic Waves of CT Scanners and MRI Scanners for Applications

ABSTRACT

CT scanners use X-rays and MRI scanners use radio waves.  CT scanners are used for all objects and MRI scanners are used only for living objects, objects with water contents and hydrated objects. These known things are analysed and a basic difference between the electromagnetic waves used in CT scanners and the electromagnetic waves used in MRI scanners is explained in this article. The electric fields in all objects are considered as the reason for applicability of CT scanners to all objects and the magnetic fields in all living beings are considered as the reason for applicability of MRI scanners to living beings. The applications of MRI scanners for all objects having fluid flows leading to magnetic fields are explained. The applications of MRI scanners for some objects with water contents are also explained.  Justifications for new reasons are provided in this article, when there are no justifications for old reasons.
