Aliasing Artifact occurs when signal collection is insufficient or the bandwidth of signal collection is narrow, and can appear in both frequency encoding and phase encoding directions, but it mainly occurs in phase encoding directions. It usually occurs when a field of view(FOV) is smaller than the size of an object is selected[1]. In foot and ankle MRI scan[fig]1, a phenomenon in which the opposite anatomical structure appears inside the field of view(FOV) and such artifacts can cause impairment in image diagnosis by creating unnecessary illusion, such as misidentifying the lesion or covering the lesion [2],[3]. Therefore, it is very important to eliminate or minimize aliasing artifacts. Methods for eliminating aliasing artifacts are mainly by applying pre-saturated pulses to the software or increasing the number of samples in the direction of phase encoding[3], but this causes many disadvantages, such as increasing the scan time and increasing the SAR (Specific Absorb Rate). Among various materials, it was found that carbon fabric fiber is a non-metal that can shield RF. Therefore, in this study, we tried to present reference materials by experimenting and evaluating the RF shielding performance and safety of Self-made Carbon Fabric Fiber Tool against thermal injury.
