Currently, Fourier analysis is a method for obtaining the phase and amplitude images used to evaluate abnormalities of cardiac contraction. Since this technique is time-consuming, the present work investigates the application of another algorithm used in digital signal processing: the Walsh- Hadamard transform ( WHT ). This method provides a 48% time saving because it requires only elementary algebraic operations. The study presents the results obtained processing 30 blood-pool cardiac acquisitions in various diseases. No significant difference was found in the pairs of maps and in the parameters chosen for comparison of the data.
目前，傅里叶分析是一种用于获取用于评估心脏收缩异常的相位和振幅图像的方法。由于该技术耗时，本研究调查了数字信号处理中使用的另一种算法的应用：沃尔什-哈达玛变换（WHT）。该方法节省了48%的时间，因为它只需要基本的代数运算。该研究展示了对30例各种疾病的血池心脏采集数据进行处理所获得的结果。在用于比较数据的成对图谱和所选参数方面未发现显著差异。
