Patent Number Title Of Patent Date Issued
7122008 Blood pressure diagnostic aid October 17, 2006
A medical diagnostic method using systolic and diastolic blood pressures, and pulse frequency of a patient is provided to compute a normalized diastolic distensibility value and a normalized peripheral resistance value, and to automatically compute the product of the normalized diast
6974415 Electromagnetic-acoustic imaging December 13, 2005
Ultrasound induced by RF irradiation within FDA exposure limits is produced with sufficient signal-to-noise ratio to allow acquisition of sub-millimeter resolution images within practical time frames.
6535625 Magneto-acoustic imaging March 18, 2003
An apparatus having a coil of wire, energized by a repetitively pulsed radio frequency (RF) power source to provide electromagnetic fields to a region within a body. A scanning, directional hydrophone acoustically connected to the body, samples ultrasonic radiation generated by the RF
5726444 Ultrasonic directional fiber-optic hydrophone March 10, 1998
A high sensitivity, high frequency directional hydrophone is disclosed which utilizes flexible optical waveguide wrapped about an hemispherical mandrel located at the focus of a paraboloidal acoustic reflector.
5402786 Magneto-acoustic resonance imaging April 4, 1995
A less expensive apparatus and associated method for Magnetic Resonance Imaging (MRI) of body tissues are disclosed. A physician uses an ultrasonic detector in combination with a weak magnetic field and pulsed, low frequency R.F. generator. The patient lies partially within the field
