Device and method for spatiotemporal reconstruction of a moving vascular pulse wave in the brain and other organs

摘要: The brain appears to have organized cardiac frequency angiographic phenomena with such coherence as qualify vascular pulse waves. Separate arterial and venous waves may be resolved. This disclosure states the method of extracting a spatiotemporal reconstruction present in an angiogram obtained at faster than frequency. A wavelet transform is applied each pixel-wise time signals angiogram. If there motion alias then instead high resolution overall intensity curve cross-correlated temporal transforms signals. result filtered for scale inverse transformed. gives complex-valued grid phenomena. It rendered brightness-hue color model or subjected further analysis.
