Optical high-frequency contrast analysis
WebDuring high-frequency rotational angioplasty (HFRA), myocardial contrast enhancement (echo contrast) was observed by means of two-dimensional echocardiography. In order to … WebThis suggests that the two higher spatial frequency results are not necessary as the same information may be more reliably provided by a logMAR VA chart. 45, 46, 56 Therefore if VA is already reliably measuring the high spatial frequency end of the contrast sensitivity function, all that remains is to measure low spatial frequencies reliably.
