20120301839 | METHOD AND APPARATUS FOR THE ASSESSMENT OF PULPAL VITALITY USING LASER SPECKLE IMAGING - The invention includes a noninvasive method for characterizing dental pulpal vitality of a tooth including the steps of irradiating the tooth with at least partially coherent light, and speckle imaging to provide quantitative feedback to an end user of pulpal blood flow in the tooth, and the tangible records made by such a method. The invention also includes an apparatus for noninvasively characterizing dental pulpal vitality of a tooth comprising a source of at least partially coherent light for irradiating the tooth characterized by a speckle pattern, optics for directing the at least partially coherent light onto the tooth, including a corresponding pulpal cavity within the tooth, a detector for detecting transmission of the at least partially coherent light through the tooth, and a processor coupled to the detector speckle imaging to provide a quantitative feedback of pulpal blood flow in the tooth. | 11-29-2012 |

20100041938 | MULTI-IMAGER COMPATIBLE ROBOT FOR IMAGE-GUIDED INTERVENTIONS AND FULLY AUTOMATED BRACHYTHERAPY SEED - Featured is a robot and a needle delivery apparatus. Such a robot comprises a plurality of actuators coupled to control locating any of number of intervention specific medical devices such as intervention specific needle injectors. Such a robot is usable with image guided interventions using any of a number of types of medical imaging devices or apparatuses including MRI. The end-effector can include an automated low needle delivery apparatus that is configured for dose radiation seed brachytherapy injection. Also featured is an automated seed magazine for delivering seeds to such an needle delivery apparatus adapted for brachytherapy seed injection. | 02-18-2010 |
20100240989 | ROBOT FOR COMPUTED TOMOGRAPHY INTERVENTIONS - A system and method for CT guided instrument targeting including a radiolucent instrument driver; a robot and a control box. The robot includes a robotic module that positions the radiolucent driver about two directions coincident a predetermined point. The control device is connected to the robot and the radiolucent instrument driver. The control driver sends a robot control signal to the robot that causes the robotic module to place the radiolucent instrument driver in a desired orientation with respect to the predetermined point. After the radiolucent instrument driver is in the desired orientation, the control device sends a driver control signal to the radiolucent instrument driver that causes the radiolucent driver to insert a medical instrument or device through the predetermined point to a location proximate a target point in a patient. | 09-23-2010 |
20120076681 | PNEUMATIC STEPPER MOTOR - A stepper motor suitable for use in a medical imaging environment has (a) a cylindrical central gear having an external surface with circumferentially distributed and radially directed teeth, (b) a shaft for mounting the central gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical hoop gear having a bore with an internal surface having circumferentially distributed and radially directed teeth, (d) level arm crank mechanisms for mounting the hoop gear such that it is constrained to move in translational-circular motion about the central gear's centerline, wherein this central gear is further configured to fit within the hoop gear's bore in such a manner that a plurality of the central gear and hoop gear teeth intermesh and cooperate so that the planetary movement of the hoop gear causes the central gear to rotate, and (e) piston mechanisms for applying a fluid pressure driven force to specified points on the hoop gear so as to cause its movement. | 03-29-2012 |

20100234856 | ROTATING NEEDLE DRIVER AND APPARATUSES AND METHODS RELATED THERETO - Featured is a medical instrument driver, a robotic apparatus embodying such a medical instrument driver and methods related thereto for inserting a medical instrument into tissue of a mammal (e.g., human). Such medical instruments include medical needles, biopsy needles, trocars, cutters and introducers. Such a medical instrument driver according to the present invention is configured and arranged so that medical instrument is rotated as it is being moved longitudinally for insertion into the tissue such that the medical instrument is spiraling as it pierces and traverses the tissue to the target area. | 09-16-2010 |

20140039314 | Remote Center of Motion Robot for Medical Image Scanning and Image-Guided Targeting - The present invention pertains to a remote center of motion robot for medical image scanning and image-guided targeting, hereinafter referred to as the “Euler” robot. The Euler robot allows for ultrasound scanning for 3-Dimensional (3-D) image reconstruction and enables a variety of robot-assisted image-guided procedures, such as needle biopsy, percutaneous therapy delivery, image-guided navigation, and facilitates image-fusion with other imaging modalities. The Euler robot can also be used with other handheld medical imaging probes, such as gamma cameras for nuclear imaging, or for targeted delivery of therapy such as high-intensity focused ultrasound (HIFU). 3-D ultrasound probes may also be used with the Euler robot to provide automated image-based targeting for biopsy or therapy delivery. In addition, the Euler robot enables the application of special motion-based imaging modalities, such as ultrasound elastography. | 02-06-2014 |
20150065886 | COHESIVE ROBOT-ULTRASOUND PROBE FOR PROSTATE BIOPSY - An embodiment in accordance with the present invention provides a device and method for a transrectal ultrasound (TRUS) guided prostate biopsy. The device includes an ultrasound wand equipped with a lateral fire ultrasound sensor. The ultrasound wand also defines a channel having an oblique path though the wand. The channel accommodates a biopsy needle, which can be pivoted as well inserted through the channel to different depths in order to perform a biopsy of the prostate. The device therefore uses only three degrees-of-freedom of movement in order to obtain the biopsy samples. Additionally, the ultrasound wand can be used to generate a three-dimensional image of the prostate. | 03-05-2015 |
