摘要： The present disclosure is directed to an apparatus for an improved ultrasound eye scanning device wherein the size of the scan head is reduced significantly and the entire instrument can be placed on a desktop. The improved ultrasound eye scanning device also utilizes imaging goggles to enable better coupling between the patient and the instrument. The imaging goggles also allow both eyes of the patient to be scanned without the patient moving. Another innovation of the ultrasound imaging system according to the present disclosure is the use of the contralateral (opposite) eye for fixation and focusing during scanning.

摘要： A disposable eye piece system, including the eye piece and other disposable components, for a precision ultrasonic scanning apparatus is disclosed. The eye piece includes a fill port, a vent port and a drain port molded into the base of the eye piece. An RF Identification chip may be molded into the plastic base of the eye piece or, alternately into the conformable face seal of the eye piece. The components of a disposable eye piece system form an integrated disposable package that can be assembled, packaged, transported and used while maintaining the eye piece and saline solution in a sterile condition. The protective shipping container 1) protects the eye piece from damage, human contact and exposure to ambient air during shipping and storage and 2) allows the scanning physician or technician to attach the eye piece to the scanning machine without compromising the sterile condition of the eye piece.

摘要： The present disclosure relates to ultrasound imaging and treatment of an eye and in particular directed to an apparatus and method for reducing intraocular pressure by 1) ablating the ciliary process which is the structure responsible for production of aqueous humor and 2) by vibrating the trabecular mesh to stimulate better drainage of fluid through the trabecular mesh and out of the eye. The present disclosure describes an apparatus and method for forming a high precision image of the eye wherein the resolution is sufficient to image, for example, ciliary body and region around the trabecular mesh. The present disclosure further discloses an imaging transducer and an irradiating therapeutic transducer that can be mounted such that they are movable between a plurality of positions.

摘要： The present disclosure is directed to a system and method that detects and measures a vault of an anterior segment of an eye of a patient. The system and method locate an implanted contact lens (ICL) between a cornea and a natural lens, form a B-scan of the eye based on the received ultrasound pulses, removes background pixels, such as by binarizing and thresholding, from the B-Scan from a grayscale color palette to a black/white color palette, determines, from the resulting B-scan a fiduciary location in the anterior segment of the eye, and forms using the resulting B-scan and fiduciary location, a vault map mapping a distance between an anterior segment surface and a posterior surface of the ICL along a plurality of lines drawn perpendicular to a local surface of the anterior segment surface.

摘要： The present disclosure is directed to a precision ultrasound scanner for imaging, for example, the prostate in a way that produces a superior image of the prostate while removing the iatrogenic risk and patient discomfort associated with other methods of providing an ultrasound image of the prostate. The present disclosure describes an apparatus and method for forming a high precision image of the prostate from outside the patient's body wherein the resolution in sufficient to image, for example, cancerous lesions on the surface of the prostate. To achieve such images, coded excitation, tissue harmonic imaging, advanced transducers operating in the 10 MHz to 40 MHz range is used to achieve a useable signal-to-noise reflection while being able to position the imaging transducer as close as possible to the prostate without risk or discomfort to the patient. The present disclosure further discloses an imaging transducer and an irradiating therapeutic transducer can be mounted such that they are movable between a plurality of positions. The irradiating transducer is, for example, about a 12 MHz transducer with a focal length of about 20 mm to about 40 mm that would produce a strong second harmonic at about 24 MHz that could be used for imaging. The imaging transducer has, for example, a focal length of about 10 mm to about 20 mm and typically operates in the range of about 25 MHz to about 40 MHz.

摘要： A method and apparatus are disclosed for integrating optical coherence tomography (OCT) and very high frequency ultrasound (VHFU) imaging systems. An OCT probe and reference arm are mounted along with an ultrasound probe on a carriage capable of rotational, linear, and/or arcuate motion. The probe carriage may be immersed in water or other suitable medium. The OCT and VHFU probes move about the cornea surface such that the probe axes are substantially perpendicular relative to the cornea surface throughout a scan. The probes are able to be scanned in an arcuate path across the entire cornea surface. The method and apparatus disclosed are also directed towards providing a positioning mechanism and scan head comprising an arcuate guide track wherein only an OCT probe is mounted on the probe carriage. This embodiment allows the OCT probe beam to remain substantially perpendicular to the cornea and lens surfaces.
