Abstract: In another aspect, the present invention relates to a method for determining the position and orientation of an anchor attached to the skull of a patient from a topographic image of the anchor acquired therefrom. In one embodiment, the method includes the steps of simulating an image of the anchor that matches the acquired topographic image of the anchor, determining the position and orientation of the anchor from the simulated image of the anchor, and determining the position and orientation of the anchor in the acquired topographic image of the anchor from the position and orientation of the anchor determined from the simulated image of the anchor. The simulating step comprises the step of modeling the anchor with an object that has a geometric shape simpler than that of the anchor.

Abstract: A method and system of compensation for intra-operative organ shift of a living subject usable in image guide surgery. In one embodiment, the method includes the steps of generating a first geometric surface of the organ of the living subject from intra-operatively acquired images of the organ of the living subject, constructing an atlas of organ deformations of the living subject from pre-operatively acquired organ images from the pre-operatively acquired organ images, generating a second geometric surface of the organ from the atlas of organ deformations, aligning the second geometric surface of the organ to the first geometric surface of the organ of the living subject to determine at least one difference between a point of the first geometric surface and a corresponding point of the second geometric surface of the organ of the living subject, which is related to organ shift, and compensating for the intra-operative organ shift.

Abstract: Certain aspects of the present disclosure are directed to a method of applying infrared neural stimulation (INS) to the central nervous system (CNS) of a target. The methods includes applying a pulsed infrared laser at a stimulation site in the CNS; and evoking responses from a region of interest of the CNS that is at or adjacent to the stimulation site by the pulsed infrared laser. In the method, the pulsed infrared laser penetrates a predetermined penetration depth of the stimulation site. Certain aspects of the present disclosure are directed to an apparatus for applying INS to the CNS of a target. The apparatus includes a generator generating a pulsed infrared laser, which penetrates a predetermined penetration depth of a stimulation site to evoke a response from the CNS, and an optical medium adapted for delivering the pulsed infrared laser at the stimulation site of the CNS.

Abstract: Diffraction gratings comprising a substrate with protrusions extending therefrom. In one embodiment, the protrusions are made of a porous material, for example porous silicon with a porosity of greater than about 10%. The diffraction grating may also be constructed from multiple layers of porous material, for example porous silicon with a porosity of greater than about 10%, with protrusion of attached thereto. In some embodiments the protrusions may be made from photoresist or another polymeric material. The gratings are the basis for sensitive sensors. In some embodiments, the sensors are functionalized with selective binding species, to produce sensors that specifically bind to target molecules, for example chemical or biological species of interest.

Abstract: Systems and methods for collecting and processing physical space data for use while performing an image-guided surgical (IGS) procedure are provided. The system and method includes obtaining a computer model of a non-rigid structure of interest in a patient and performing a rigid alignment of the computer model and surface data in a patient space associated with at least a portion of the non-rigid structure. The system and method also include computing a deformation of the computer model that provides a non-rigid alignment of the computer model and surface data, the deformation computed using a set of boundary conditions defined for each node of the computer model based on the rigid alignment and a kernel function. Additionally, the system and method can include displaying data for facilitating the IGS procedure based on the deformation.

Abstract: Systems and methods for estimating projectile trajectory and projectile source location are provided. A method for estimating location information associated with a supersonic projectile propelled from a source includes recording sound at a first location using a single microphone during travel of the supersonic projectile to produce an acoustic recording. The method further includes estimating a miss distance between the first location and a trajectory of the projectile based on the shockwave length. Locating a projectile source includes concurrently recording sound at multiple locations and generating data sets associated with the locations, each of the plurality of data sets including a miss distance, a range, a time of arrival of a muzzle blast from the source, and a time of arrival of a shockwave produced by the projectile. Additionally, the method includes calculating an approximate location of the source at each of the locations based on the data sets.

Abstract: Cyclen-based chelates can be used as contrast agents for multi-modal imaging of tissue cells. The cyclen-based chelates are preferably polyazamacrocyclic molecules formed from 1,4,7,10 tetraazacyclododecane (“cyclen”) having varying chelating ions, phosphoester chains, and light harvesting moieties. By changing the chelating ion, phosphoester chain length and/or the light harvesting moiety different imaging techniques, such as MRI, CT, fluorescence and absorption, x-ray and NIR, may be employed to image the tissue cells. Additionally, the cyclen-based chelates may be conjugated to provide for site-specific delivery of the cyclen-based chelate to the desired tissue cells. The cyclen-based chelates may also be delivered to the tissue cells by attaching the cyclen-based to a polymeric delivery vehicle. Although these cyclen-based chelates have a wide variety of application, the preferred use is for imaging of cancer cells, such as brain cancer, for improving resection of a cancerous tissue.

Abstract: The present invention provides for the simultaneous assessment of a plurality of tissue regions or microregions, the benefit being homogeneity of the sampling, both in terms of tissue content and timing. Discrete regions of a tissue sample, such as those demarcated by microwells formed within the tissue itself or tissue plugs removed from the tissue in a spatially referenced fashion, can be treated with one or more physical or chemical treatments to liberate target molecules of interest. Subsequent analysis of said target molecules by, e.g., mass spectroscopy, permits identification of a variety of biological parameters, including those associated with disease or therapy.
Abstract: The present invention provides simple and inexpensive assays for the detection of virtually any analyte in any sample that is in liquid form or that can be solubilized. The assays utilize the fluid dynamics of drop evaporation whereby soluble materials, including analytes and particles binding thereto, are drawn to the edge of the drop and ultimately form a concentrated residual ring. The presence or absence of certain reagents can then be detected through a number of different approaches.
