Abstract:
A magnetic resonance imaging method comprising the steps of:configuring k spaces out of views ranging from a first view through a Vth view which differ in quantity of phase encoding; collecting data by a number of times of addition N in an nth view, wherein nth is between first view and Vth view; arithmetically averaging data of said nth view of said collected data thereby resulting in average data An; and using said average data An for image reconstruction, wherein the number of times of addition N are determined as follows: (Step E1) set number at times of addition to be (Nâˆ’N/2) from a first view till (V/8)-th view; (Step E2) set number of times to be (Nâˆ’N/2) from (V+V/8+1)-th view till Vth view; (Step E3) set number of times of addition to be (N+N/2) from (V/8+1)-th view till (Vâˆ’V/8)-th view; and (step E4) set number of times of addition from (V/8+1)-th view till (Vâˆ’V/8)-th to number of times resulting from discrete processing of addition of (Nâˆ’N/2) to product of multiplication of balance of subtraction of (Nâˆ’N/2) from earlier calculated number of times of addition by either a Hamming function or a Hanning function.
