Abstract: A dock ramp assembly for a docking opening on a facility; the assembly comprising a seal for sealing the docking opening with at least one access door opening on a transport vehicle when the vehicle is docked with the facility; the seal comprising an upper seal which extends over a top peripheral edge of the docking opening and adjacent side peripheral edges of the docking opening, and a lower seal which extends beneath the lower peripheral edge of the docking opening, such that the seal extends around the entire periphery of the docking opening to form a complete seal between the docking opening and the access door opening when the vehicle is docked with the facility; the assembly further comprising a retractable bumper which is transitioned from an extended, in-use position in front of the docking opening, to a retracted, stored position remote from the docking opening.

Abstract: A method of formatting data for identifying colon polyps in a Computed Tomography Colonography (CTC) dataset comprising the steps of: extracting colon surface data, from the CTC dataset, within a sub-volume centered on a candidate polyp (CP) seed point; identifying individual sets of points corresponding to the CP's body and CP's base within the sub-volume; selecting the points corresponding to the body; re-formatting the candidate polyp by projecting the selected points corresponding to the body on to a tangent plane; and generating a series of cutting planes based on the reformatted candidate polyp.

Abstract: The present invention is directed towards a dock ramp assembly (100) for a docking ope (104) on a facility; the dock ramp assembly comprising a seal for sealing the docking ope with at least one access door ope on a transport vehicle when the transport vehicle is docked with the facility; the seal comprising an upper seal (504) which extends over a top peripheral edge (106) of the docking ope (104) and adjacent side peripheral edges (110A, 110B) of the docking ope, and, a lower seal (600) which extends beneath the lower peripheral edge (108) of the docking ope, such that the seal extends around the entire periphery of the docking ope (104) and the seal is arranged to form a complete seal between the docking ope and the access door ope when the transport vehicle is docked with the facility; wherein, the dock ramp assembly (100) further comprises a retractable bumper (124A, 124B) which is transitioned from an extended, in-use position in front of the docking ope, to, a retracted, stored position remote from the

Abstract: A method of processing a 3-dimensional Computed Tomography Colonography data set to remove tagged material is disclosed. The method involves the preliminary processing step of classifying voxels in the data set as corresponding to air, tagged material or colon tissue. Methods of overcoming erroneous classification of Partial Volume air/tagged material interface voxels are disclosed. The present invention also provides for methods of circumventing problems resulting from removal of tagged material from a CTC data set, which can result in the erosion of soft-tissue structures partially covered by tagged colonic fluid.

Abstract: A method of formatting data for detecting flat polyps in a Computed Tomography Colonography, CTC, dataset comprising the steps of: extracting colon surface data, from the CTC dataset, within a sub-volume centred on a candidate polyp seed point; identifying individual sets of points corresponding to the candidate polyp's body and the candidate polyp's base within that sub-volume; projecting the set of points corresponding to the candidate polyp's body on to a tangent plane via a normal vector, wherein the normal vector is calculated from the best fitting plane to the set of points corresponding to the candidate polyp's base; isolating a new seed point for the candidate polyp from the projected data; locating the nearest surface point to the new seed in the extracted dataset above, and region-growing the surface ab initio from this point; identifying individual sets of points corresponding to the candidate polyp's body and the candidate polyp's base in the region-grown surface, and determining the normal vector

Abstract: The present application teaches an implementation of an ultra-compact range sensor based on aperture varying passive depth from defocus. An embodiment of the present application teaches a range sensor, which is a fast LCD matrix that allows the acquisition of a plurality of images with variable focal levels by changing the size of the aperture of a typical lens. The range sensor of the present application may be implemented in mobile devices or used in the construction of medical endoscopes able to perform depth recovery.
