Enhanced High Resolution Breast Imaging Device And Method Utilizing Non-Ionizing Radiation Of Narrow Spectral Bandwidth

View page
US Patent:
6345194, Feb 5, 2002
Filed:
Mar 21, 2000
Appl. No.:
09/532365
Inventors:
Robert S. Nelson - San Diego CA, 92106
Reuven D. Zach - Los Angeles CA, 90046
International Classification:
A61B 600
US Classification:
600425, 600473, 600476, 2503381, 2503411, 2503581, 2503601
Abstract:
The present invention provides a method and apparatus for high resolution breast imaging using collimated non-ionizing radiation in the near ultraviolet, visible, infrared and microwave regions (i. e. âlightâ) rather than ionizing x-radiation. The incident collimated light is transmitted through and backscattered out of a breast and loses intensity due to the properties of the breast materials in the beam path. Normal and diseased breast materials may exhibit comparatively distinct characteristics when exposed to different wavelengths of light and thereby be differentiated. Collimation can be used to control the level of scattered radiation which reaches the detector. Transmission and/or backscattered measurements can be acquired from a number of perspectives. Radiation coupling materials can be employed during image acquisition to enhance radiation coupling into and out of the breast as well as well as providing desirable absorption, scattering, heat removal, lubrication, and tissue compensation properties. The effects of the pattern of a structured collimator on image quality can be reduced by moving the structured (patterned) collimator in a reciprocating manner during image acquisition.

Apparatus For Enhancing The Survivability Of Exposed Structures

US Patent:
6519901, Feb 18, 2003
Filed:
Feb 28, 2001
Appl. No.:
09/797145
Inventors:
Robert S. Nelson - San Diego CA, 92106
Reuven D. Zach - Los Angeles CA, 90046
International Classification:
A01G 1310
US Classification:
52101, 43124, 47 23, 34082536
Abstract:
An apparatus for the protection of exposed structures, in particular cables, poles, pipes, and towers from destructive interactions with external threats, including: various animals (including man), plants, and machines as well as from general environmental hazards. The protective configurable sheath apparatus may be optimized for a specific candidate (type of animal, plant, environmental hazard, machine) or for a range of candidates. A configurable sheath fully or partially encompasses the exposed structure to be protected. The sheath may be attached in a variety of ways and is typically designed so that it is removable or upgradable. Thus, the sheath can be employed on a temporary basis or it can be replaced/modified as is needed. This versatile configurable sheath permits customization of commercially-available, mass-produced structures as well as retrofitting installed structures. Sheath base materials may serve multiple functions.

Anthropomorphic Mammography And Lung Phantoms

View page
US Patent:
57199167, Feb 17, 1998
Filed:
Jun 5, 1995
Appl. No.:
8/470353
Inventors:
Robert S. Nelson - San Digeo CA
Reuven D. Zach - Los Angeles CA
International Classification:
G01D 1800
US Classification:
378207
Abstract:
The present invention provides an apparatus and a method of use and construction of Anthropomorphic Mammography and Lung Phantoms. The phantoms resolve deficiencies that currently exist in the practice of mammography and lung x-ray imaging. The mammography phantom provides mammography practitioners a training tool in the practice of proper patient breast positioning and in optimal patient x-ray exposure. The mammography phantom can be used to generate x-ray images similar to mammography patient x-ray images. The mammography phantom simulates normal breast tissue and tissue irregularities and anomalies associated with various known breast pathologies such as microcalcifications, cysts, tumors, etc. The mammography phantom preferably comprises the shape of an upper torso of a woman including one or two breast simulators which can vary in size, density, compressibility, and stretchability. The mammography phantom is preferably constructed such that the breast simulators can be detached from the upper torso phantom (which can include articulating arms) and replaced, enabling the mounting of a variety of breast simulator types.

High Resolution Device And Method For Imaging Concealed Objects Within An Obscuring Medium

View page
US Patent:
62165402, Apr 17, 2001
Filed:
Dec 10, 1996
Appl. No.:
8/779011
Inventors:
Robert S. Nelson - San Diego CA
Reuven D. Zach - Los Angeles CA
International Classification:
G01N 2900
US Classification:
73633
Abstract:
A method and apparatus are provided for imaging and identifying concealed objects within an obscuring medium using radiation (optical, photo-acoustic, ionizing, and/or acoustic) optimized for imaging (e. g. temporal properties, spectral bandwidth, directionality, polarization, etc. ). Radiation propagates through, interacts with, exits the medium and the object, and is detected/imaged. Image quality can be improved if radiation is collimated and/or if transmission and/or backscattered measurements from a number of perspectives are used to improved image reconstruction. Coupling materials can be employed during image acquisition to enhance radiation coupling as well as providing desirable absorption and scattering properties. Contrast materials and agents can also aid in the detection of concealed objects. Adaptive methods, e. g.

High Resolution Breast Imaging Device Utilizing Non-Ionizing Radiation Of Narrow Spectral Bandwidth

View page
US Patent:
46492755, Mar 10, 1987
Filed:
Aug 27, 1984
Appl. No.:
6/624467
Inventors:
Robert S. Nelson - Santa Monica CA
Reuven D. Zach - Los Angeles CA
International Classification:
G01N 2127
G01N 2159
US Classification:
2503581
Abstract:
The present invention provides a method and apparatus for high resolution breast imaging which uses collimated light (in the near Ultraviolet, visible, or infra-red) of a narrow spectral bandwidth rather than ionizing X-ray radiation. The collimated light is transmitted through the breast, losing intensity due to the reflective, absorptive and refractive properties of the breast materials in the beam path. Normal and diseased breast materials may exhibit distinctive characteristics from each other when exposed to different wavelength of light. Several images can be acquired at distinct wavelengths of light to help differentiate normal and diseased breast materials. Light transmitted through the breast is recorded by a photodetector, generating an analog signal which can then be digitized and made available to a computer for analysis, processing and display. The light transmitted through the breast can be collimated to reduce the level of scattered light which reaches the photodetector, improving image quality.

Enhanced High Resolution Breast Imaging Device And Method Utilizing Non-Ionizing Radiation Of Narrow Spectral Bandwidth

View page
US Patent:
59998369, Dec 7, 1999
Filed:
Feb 2, 1996
Appl. No.:
8/597447
Inventors:
Robert S. Nelson - San Diego CA
Reuven D. Zach - Los Angeles CA
International Classification:
A61B 500
US Classification:
600407
Abstract:
The present invention provides a method and apparatus for high resolution breast imaging using collimated non-ionizing acoustic radiation and electromagnetic radiation in the near ultraviolet, visible, infrared and microwave regions (i. e. "light") rather than ionizing x-radiation. The light used is of a narrow spectral bandwidth in that the optical properties of interest are relatively uniform over the bandwidth. The incident collimated light is transmitted through and backscattered out of a breast. Normal and diseased breast materials exhibit comparatively distinct characteristics when exposed to radiation and are thereby differentiated. Collimation can also be used to control the level of scattered radiation. Radiation coupling materials can be employed during image acquisition to enhance radiation coupling into and out of the breast as well as providing desirable absorption and scattering properties. Additional scatter reduction and/or improved sensitivity can be attained by compressing a region of the breast using contoured and/or flat compression plates of various sizes which may include an open region allowing access to the surface of the breast for irradiating a portion of the breast.

The upper torso of the mammography phantom also preferably provides a rib cage (with pectoralis major muscle) for the mounted breast simulators, providing an additional element of realistic patient simulation.
