Abstract:
1. A magnetic resonance imaging apparatus comprising: a scan unit configured to scan an object to be examined and acquire an analog nuclear magnetic resonance (NMR) signal; an analog-to-digital (A-D) conversion unit configured to convert the analog NMR signal into a first digital signal represented in binary notation; and a signal processing unit configured to generate a magnetic resonance (MR) image based on a second digital signal represented in binary notation, said A-D conversion unit comprising: an input unit configured to convert the analog NMR signal inputted from said scan unit into the first digital signal represented in binary notation, and convert the first digital signal represented in binary notation into a gray code-converted digital signal; and an output unit configured to inversely convert the gray-coded digital signal into a second digital signal represented in binary notation, and output the second digital signal to said signal processing unit, said input unit and said output unit coupled by a digital signal bus configured to transmit the gray-coded digital signal in a time-shared manner between said input unit and said output unit.
