Background/Objectives: Filter in MRI front-end receiver chain plays an important role in rejecting the undesired image frequencies. These filters are designed for RF and IF stages in the front-end chain. Methods/Statistical analysis: Bandpass filters are designed for obtaining particular frequency band. The MRI frequency lies in this frequency band selected by the bandpass filter. Different types of prototypes for design of bandpass filter are discussed here. The major two prototypes of filter are designed and simulated. Findings: There are various practical filter prototypes in which the major two filter prototypes: Butterworth and Chebyshev are analyzed. These filters give better response and results for the MRI frequency. They are designed at novel frequency of 63.87 MHz which is the frequency or the MRI receiver chain. The filter is designed and simulated at different orders for obtaining better performance with respect to the insertion loss and return loss. The novelty of the results obtained is that the insertion loss is minimum at the frequency of the MRI receiver front-end chain. This will reduce the loss in the MRI system, increases gain of system, and thus image obtained will be more clear and accurate. Application/Improvements: Better filter can be designed by reducing the passband bandwidth which will provide more accuracy to the system.
