US Classification:

Abstract:

A microwave breast cancer imaging method that includes an examination table that is both comfortable and reliable is provided that includes a support system and an orientation system such that breasts can remain in a fixed position to allow for scanning. A horizontal microwave and optically transparent scan plate forms part of the top of the examination table. The imprint of the breasts on the scan plate may be visually displayed to aid in the orienting of each breast such that all volumes within the breast are scanned. Microwave power is then scanned upward through the scan plate to develop a microwave response that is indicative of the presence of a lesion. After scanning, the visual imprint of the breast is recorded. As needed, microwave equipment can be included within a microwave shielded enclosure that also forms part of the scan table. Spurious leakage of microwave power may be further suppressed by use of microwave-absorbing materials, within the enclosure and, in the padding that covers the surface of the examination table and removable pads.

International Classification:

H04R 1/00

US Classification:

381423000

Abstract:

A speaker system including a horn having walls extending from a throat of the horn to a mouth of the horn and defining a cavity within the horn. At least one of the walls includes a panel that is contoured to the shape of the wall and that is configured to move with respect to the wall. A driver is disposed proximate the at least one wall and configured to cause the panel to vibrate and emit sound waves into the cavity of the horn.

US Classification:

342 25 A, 342165

Abstract:

An imaging system for generating a three dimensional image of tissue of a patient is provided. The imaging system comprises of a transmitter, receiver, antenna system and a display element to form a synthetic aperture radar system that displays a three dimensional view of the tissue. The SAR system has been configured to operate in the near field as opposed to current equipment which can only perform satisfactorily in the far field. A calibration technique has been utilized that allows the system to perform as well as other systems that operate using far field techniques but allows for a much simpler, cost effective system.
