Feasibility Study on the Use of Low-Power Mini PC for Magnetic Resonance Imaging Application

Abstract

Digital medical imaging is a process of constructing digital images for medical applications. One of them is Magnetic Resonance Imaging or MRI. Simple image construction uses the Inverse FFT algorithm which is an efficient algorithm. This study is to evaluate the performance of a magnetic resonance imaging system using a mini-computer system with low power. The design constraints are the system must be energy-efficient and also low cost. The first result of this study indicates the mini PC jetson Nano can reconstruct MRI images in a maximum time of 67.13 seconds from k-space data using the inverse FFT algorithm measuring 2048 with an electrical energy consumption of 150 watts-second (Joule). The second result of this research shows that the MRI reconstruction software makes the CPU spends time the most at the DoRSS function. The latest result of this research inspired us to do new research to improve performance and to reduce energy consumption further.
