2006-145 – Heart diseases are detected by producing a series of ultrasound images that depict the blood flow pattern in the left ventricle at successive phases of the cardiac cycle. The blood flow pattern images are produced by injecting a diluted contrast agent and tracking the contrast agent particles as they flow through the left ventricle by acquiring ultrasound images at a high frame rate.
Quantitative Imaging of Iron as a Marker of Vulnerable Atherosclerotic Lesions Using Computed Tomography
2006-017 – Intraplaque hemorrhage represents an event in the induction and/or as a consequence of instability of advanced atherosclerotic lesions. Iron should accumulate in a lesion after hemorrhage, as part of each erythrocyte, whether isolated or within macrophage-derived cells that have phagocytosed the red blood cells. Moreover, ectopic neovascularization is also a major feature of... Read More
2005-063 – Imaging systems, such as computed tomography, magnetic resonance, or echocardiography are complex devices that not only acquire imaging data but also provide various measurements and displays based on the data. Clinical diagnostic decisions, based on the imaging data, are subjective, experience-based, and affected by stress. This invention describes algorithmical implementation of a trainable... Read More
In vivo Visualization of Alzheimer's Amyloid Plaques by MRI in Transgenic Mice without a Contrast Agent
2004-139 – One of the cardinal pathologic features of Alzheimer’s disease (AD) is formation of senile or amyloid, plaques. Transgenic mice have been developed that express one or more of the genes responsible for familial AD in humans. Doubly transgenic mice develop “human-like” plaques, providing a mechanism to study amyloid plaque biology in a controlled manner. Imaging of labeled plaques has been... Read More
2002-179 – Mayo researchers have developed a method to allow clinical x-ray imaging to reach its full potential. This is achieved by reducing the x-ray dose absorbed by the patient by orders of magnitude and by enhancing the contrast discrimination of the x-ray interaction with different soft-tissue components so that little, if any, contrast agent need be administered. The Time-Of-Flight X-ray... Read More
2001-050 – Device reproducibly positions subject’s upper extremities while allowing measurement of actively generated forearm torque against resisted rotation in variable forearm positions; used with MMV-01-049.
2001-049 – Device reproducibly positions subject’s upper extremities in field of CT imaging system; allows variable positioning of forearm rotation; allows present forearm positions to be maintained and for active force generation by patient to optimize displacement of bones to demonstrate joint instability.
1999-033 – These methods reduce the audible sound produced by ultrasound scanners in patients. Reduction of fetal stress during ultrasound examination.
1996-100 – Radiation force of arbitrary frequency is generated on the object using a single ultrasound beam. This system is used for information transmission, object detection or imaging. 3D blood flow vector imaging and imaging of internal structures of living cells.
1995-094 – In this system, a low frequency radiation force is exerted point-by-point on the object by a confocal ultrasound transducer. The amplitude of the resulting acoustic field is used to produce a two-dimensional display of the object’s cross sections. This system can produce a high resolution image from an object based on its low frequency (kHz) characteristics.
