Abstract: A method for detecting a finger is provided. The method includes obtaining a plurality of digital images including a first digital image captured by a camera from a field of view containing a background and a hand including at least one finger, and obtaining an identification of pixels of the plurality of digital images that correspond to at least one finger that is visible in the plurality of digital images rather than to the background, the pixels being identified by: obtaining, from the digital images, a Gaussian brightness falloff pattern indicative of at least one finger, identifying an axis of the at least one finger based on the obtained Gaussian brightness falloff pattern indicative of the at least one finger without identifying edges of the at least one finger, and identifying the pixels that correspond to the at least one finger based on the identified axis.

Abstract: Systems and methods used to perform non-contact patient registration of images for surgical navigation are disclosed. In some embodiments, the systems include a 3-D scanning device to capture spatial data of a region of interest of a patient and a reference frame. A digital mesh model is generated from the spatial data. A reference frame model is registered with the digital mesh model. Anatomical features of the digital mesh model and a patient registration model are utilized to register the digital mesh model with the patient registration model. A position of a surgical instrument is tracked relative to the reference frame and the patient registration model.

Abstract: The invention is a method for determining whether an input image is sufficiently sharp, comprising the steps of
providing a blur score threshold value,
inputting the input image to an image processing system,
generating, by the image processing system, a two-dimensional frequency spectrum of the input image,
generating a one-dimensional frequency spectrum from the two-dimensional frequency spectrum,
fitting a straight line on the one-dimensional frequency spectrum, and
determining a blur score value based on a residual of the fitting, and considering the input image as sufficiently sharp based on a comparison of the blur score value with the blur score threshold value.
The invention further relates to a data processing system, a computer program product and a computer readable medium carrying out the above method.-

Abstract: A method of providing user guidance. First patient image data of a patient's body is obtained. A registration instruction indicative of where to acquire a registration point relative to a surface of the body is determined. Second patient image data of the body, having been acquired by an augmented reality device, is obtained. A transformation between coordinate systems of the first and the second patient image data is determined. Based on the transformation, display of the registration instruction on a display of the AR device is triggered such that a user of the AR device is presented an augmented view with the registration instruction being overlaid onto the patient's body. The augmented view guides the user where to acquire the registration point. Also disclosed are a computing system, a surgical navigation system, and a computer program product.

Abstract: A system and method for scoring trained probes for use in analyzing one or more candidate poses of a runtime image is provided. A set of probes with location and gradient direction based on a trained model are applied to one or more candidate poses based upon a runtime image. The applied probes each respectively include a discrete set of position offsets with respect to the gradient direction thereof. A match score is computed for each of the probes, which includes estimating a best match position for each of the probes respectively relative to one of the offsets thereof, and generating a set of individual probe scores for each of the probes, respectively at the estimated best match position.

Abstract: An ultrasonic puncture guidance planning system based on a multi-modal medical image registration, which includes: an MRI sequence image rendering unit configured to receive MRI sequence images, and perform three-dimensional rendering and plot puncture points; an ultrasound sequence image reconstruction unit configured to receive ultrasound sequence images and reconstruct ultrasound volume data; a registration unit configured to perform a three-dimensional registration operation to obtain a registration transformation coefficient; and a puncture planning unit configured to receive ultrasound images of a human body acquired by an ultrasound probe, and generate and display a puncture planning image according to a system puncture point and a current ultrasonic image. An electromagnetic coordinate system under ultrasound is unified to a MRI world coordinate system through a multi-modal medical image registration, and it is determined whether the puncture point is on the ultrasound plane to guide the ultrasound for accurate puncture.

Abstract: System and method of registering a medical image of a patient in an imaging space to the patient in a physical space preferably without the use of any embedded radiopaque fiducials in medical images is provided. In one way, intra-op 2D medical images are used to register a pre-op unregistered 3D medical image. The 2D medical images are registered based on simultaneous tracking of the tracking markers on the imaging device and on the patient by a tracking device at the time of image capture. The 2D images are matched to corresponding simulated 2D images generated from the pre-op 3D image volume. Thus, registration of a pre-op 3D image to the patient is accomplished without performing another 3D scan of the patient.
