Abstract: A falloposcope is described, as is a method of screening a patient for fallopian tube and/or ovarian cancer with the Falloposcope. The falloposcope has an optical imaging subsystem capable of performing optical and fluorescence imaging, and an optical coherence tomography (OCT) channel, with a diameter of about 0.7 millimeter. The method includes inserting the falloposcope through a lumen of vagina, cervix, uterus, and fallopian tube such that a tip of the falloposcope is in proximity to a first fallopian tube or ovary of the patient; providing at least one fluorescence stimulus wavelength through an illumination fiber of the falloposcope, while imaging light at one or more fluorescence emission wavelengths through a coherent fiber bundle to form fluorescence emissions images; and determining suspect tissue from the fluorescence emission images.

Abstract: An embodiment in accordance with the present invention provides a precise catheter tracking system, Active Ultrasound Pattern Injection System (AUSPIS). AUSPIS establishes ultrasonic communication between any ultrasound external probe and internal catheter (CUTE catheter). The system receives image beacon pulses, analyzes the acquired signal, and fires one or a series of active echo pulses from the same active echo element with a proper timing, frequency, duration and amplitude. Thus it enables injection of any “virtual” pattern into the B-mode image. The pattern injected to the B-mode image is from actively encoded ultrasound field in the tissue. The encoding is based on B-mode ultrasound image formation technique, so it doesn't require hardware or software modification to the US machine. It continuously measures the local acoustic signal amplitude, by which sub-millimeter elevation localization accuracy can be achieved.

Abstract: Systems and methods for non-invasive fat reduction can include targeting a region of interest below a surface of skin, which contains fat and delivering ultrasound energy to the region of interest. The ultrasound energy generates a thermal lesion with said ultrasound energy on a fat cell. The lesion can create an opening in the surface of the fat cell, which allows the draining of a fluid out of the fat cell and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.

Abstract: A method and system for providing ultrasound treatment to a tissue that contains a lower part of dermis and proximal protrusions of fat lobuli into the dermis. An embodiment delivers ultrasound energy to the region creating a thermal injury and coagulating the proximal protrusions of fat lobuli, thereby eliminating the fat protrusions into the dermis. An embodiment can also include ultrasound imaging configurations using the same or a separate probe before, after or during the treatment. In addition various therapeutic levels of ultrasound can be used to increase the speed at which fat metabolizes. Additionally the mechanical action of ultrasound physically breaks fat cell clusters and stretches the fibrous bonds. Mechanical action will also enhance lymphatic drainage, stimulating the evacuation of fat decay products.

Abstract: In spectral pulsed wave Doppler imaging, spatial variance in signal and/or noise are reduced by combination of multiple spectra with at least partially decorrelated noise. Rather than requiring oversampling in time, the multiple spectra for one Doppler gate are created from different spatial signals. The Doppler gate is divided into sub-gates, the beamformed sample locations in the Doppler gate are grouped into two or more groups using any selection criterion, and/or different receive apertures are used to simultaneously sample the Doppler gate. Spectra for the gate are estimated from the samples with the different spatial content and then combined.
