20140249422 | INNOVATIVE COMPONENTS FOR AN ULTRASONIC ARC SCANNING APPARATUS - Embodiments of the present invention are directed to various aspects of imaging systems, including permeable and impermeable barriers separating liquid compartments, one of which contains the object to be imaged and the other an ultrasonic transducer, a fluidic bearing between a transducer carriage and guide supporting the carriage, a linear motor for the carriage, and a location sensing device for the carriage. | 09-04-2014 |
20140009741 | COMBINATION OPTICAL AND ULTRASONIC IMAGING OF AN EYE - 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. | 01-09-2014 |
20130310692 | CORRECTING FOR UNINTENDED MOTION FOR ULTRASONIC EYE SCANS - A device and method are disclosed for detecting and correcting unintended eye movements that may occur during an ultrasound scan by monitoring multiple position tracking sensors, examples being but not limited to ultrasound or optical position sensors. These position tracking sensors are in addition to the ultrasound imaging transducer and are in a fixed position on the scan head so as not to move during the scanning operation. These position tracking sensors can continuously monitor the distance to the cornea or other clearly defined anatomical features of the eye such as the posterior pigment layer of the iris during the movement of the scan head assembly and can provide continuous multi-dimensional correction for any unwanted motion of the eye relative to the scan head that may occur during the ultrasound scan. | 11-21-2013 |
20130237826 | PRECISION ULTRASONIC SCANNER FOR BODY PARTS WITH EXTENDED IMAGING DEPTH - A method and apparatus are disclosed for performing an ultrasound scan on a body part and specifically for a portable instrument which directly attaches to the surface of the body. This apparatus provides very high resolution images and greatly increased depth of imaging for high resolution ultrasound of targeted subsurface body tissues with ultrasound image resolution far superior to that of known state of the art ultrasound instruments. Targeted tissues could include but not be limited to joints, ocular structures, and internal organs. | 09-12-2013 |
20110099718 | METHOD OF POSITIONING A PATIENT FOR MEDICAL PROCEDURES - A method and apparatus are disclosed for a method for securing a patient for a medical procedure and specifically for an innovative headrest system for securing a patient for an ocular imaging procedure. The approach avoids the need for linkages and sliding rods and such. Instead, it relies on three independently movable face rests (two for the forehead or temples and one for the chin) each with a deformable cushion that is urged into conformity with the patient's head and chin during an adjustment phase of operation. Once a comfortable position and suitable conforming shape is achieved, the positions of the face rests are rigidly fixed and the shape of the cushions are rendered rigid and non-deformable, by application of a light vacuum, for the procedural or imaging phase of operation. | 05-05-2011 |
20100004538 | COMPOUND SCANNING HEAD FOR AN ULTRASONIC SCANNING APPARATUS - In one embodiment, the invention is directed to an ultrasound transducer whose holding device moves along a guide track while transducer on the end of the holing device oscillates about a known position during ultrasound transmission and receiving. In this embodiment, most refractive eye components including zonules and their connection points can be imaged. | 01-07-2010 |
20100004537 | PROCEDURES FOR AN ULTRASONIC ARC SCANNING APPARATUS - Embodiments of the present invention are directed to methods of rapidly obtaining ultrasonic images of the eye using a set of procedural options that can be automated by a positioning mechanism that can be controlled by software. | 01-07-2010 |
20090192389 | INNOVATIVE COMPONENTS FOR AN ULTRASONIC ARC SCANNING APPARATUS - Embodiments of the present invention are directed to various aspects of imaging systems, including permeable and impermeable barriers separating liquid compartments, one of which contains the object to be imaged and the other an ultrasonic transducer, a fluidic bearing between a transducer carriage and guide supporting the carriage, a linear motor for the carriage, and a location sensing device for the carriage. | 07-30-2009 |
