摘要

本文以電腦模擬腦部各組織磁振影像的訊號強度和大小順序的轉變，使初學者能藉此了解在各種不同的射頻波序列（radio frequency pulse sequeney以下簡稱波序），各組織間訊號強度變化的關係，並期望藉著模擬與演練，使操作者了解波序的意義，從而減短熟悉操作磁振儀器的時間。

A program was wrote on a personal computer, for simulating the intensity change of the various tissues of brain in M. R. I with different pulse sequences.
In this program, the change of intensity of tissues in each pulse sequence is plot on a two dimentional table. Different tissues has different curves presenting as the intensity change in selected pulse sequence and extrinsic parameters.
User may be familiarized with these changes by operating this program repeatedly, so as to reduce the time and operation cost for learning M. R. I..
