Abstract: Disclosed herein are an apparatus, method, and system for measuring the uniformity of a main magnetic field in a magnetic resonance imaging system and a recording medium thereof and, more particularly, to a method of obtaining quantitative information using measurement equipment that may be implemented in response to automatic and semi-automatic type user-selective movements so as to measure a magnetic field within a three-dimensional (3D) space using a gauss meter and a flux meter and of automatically inputting and displaying the obtained quantitative information through software in order to measure the uniformity of a main magnetic field in a magnetic resonance imaging system which greatly influences the picture quality of a magnetic resonance medical image, thereby enabling efficient performance tests, follow-up management, and establishment of a measurement standard for a magnetic resonance imaging system.
