摘要:
The application as disclosed herein describes systems and methods for performing patient registration using a surgical navigation system. This application attempts to provide for improvements upon existing systems through the addition of refinement steps used to increase the accuracy of registration and streamline said process. In some cases the improvements generally involve the manipulation of spatial data in an iterative manner.

An electronic device is provided including a processor, a communications interface coupled to the processor, a memory coupled to the processor, and a module saved in the memory. The module configures the processor to receive a first communications packet from a remote device via the communications interface including information useful for estimating a clock offset of the remote device, and determine an upper bound of the clock offset of the remote device with respect to the electronic device based on the information.

Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.
摘要:
A method, system and apparatus for controlling a surgical navigation system are provided. The method 1 comprises receiving image data at a processor from a tracking system; receiving, at a processor, an identifier of a surgical instrument within a field of view of the tracking system; generating, at the processor, output data based on the identifier of the surgical instrument; and transmitting the output data to at least one output device connected to the processor, for controlling the output device.

A user interface is provided for interacting with slides and objects provided on slides. In certain embodiments, the user interface includes features that are displayed attached to or proximate to selected slides or objects. In embodiments, aspects of the user interface may be used to preview, review, add, or modify transitions associated with animation from one slide to the next (or previous) and builds associated with animation of objects on slides.

Provided is a seal for sealing the oesophagus of a slaughtered animal such as a cow, the constituent parts of such a seal and a device and a method for sealing the oesophagus of a slaughtered animal, such as a cow, by arranging such a seal. The seal comprises a cylindrical body which can be placed in the oesophagus and is provided with a cylindrical peripheral wall with an end wall, a clamping element which can be displaced to a clamping position relative to the body for clamping oesophageal tissue between at least a part of the clamping element and the cylindrical body, thus fixing the seal in the oesophagus and thereby sealing the oesophagus, wherein the peripheral wall encloses a receiving space and is provided with an opening through which oesophageal tissue can be carried into the receiving space and is there clamped fixedly by the clamping element.

An angling rig comprises a pebble of natural stone and, secured to the pebble, an attachment ring for attaching the pebble to a fishing line. The attachment ring is secured to the pebble by means of a swivel bonded by epoxy resin adhesive in a bore formed in the pebble. The invention provides an alternative to a lead weight which is non-toxic (and therefore ecologically desirable) and also of natural form (and therefore not perceived as threatening by fish), whereby anglers may both help the environment and expect better catches.
摘要:
The invention relates to a method for manufacturing an impression of a person-specific contact surface for a sitting orthosis, comprising of providing a first flexible holder in which a quantity of separate particles is present, bringing the contact surface into the desired form by bringing the person into supporting contact in a desired position with at least the first flexible holder, fixing the contact surface by applying an underpressure in the flexible holder, removing the person after applying an underpressure in the flexible holder and making an impression of the contact surface, wherein an overpressure is applied in the at least one first flexible holder during forming of the contact surface. The invention also relates to a device for manufacturing a person-specific impression of a contact surface for a sitting orthosis.
摘要:
The present invention relates to a process of forming a sprayable pesticide or herbicide formulation having improved spray drift properties comprising the steps of, i) providing an aqueous concentrate containing pesticide or herbicide, ii) providing an aqueous concentrate containing pesticidal or herbicidal adjuvant or fertiliser, iii) forming the sprayable pesticide or herbicide formulation by combining water, the pesticide or herbicide and the pesticidal or herbicidal adjuvant or fertiliser, wherein the aqueous concentrate of pesticide or herbicide and the aqueous concentrates of the pesticidal or herbicidal adjuvant or fertiliser both contain one or more polymers capable of enhancing spray drift control. The sprayable formulation may be prepared in a spray tank into which is metered water, the concentrate containing herbicide or pesticide and the concentrate containing the pesticidal or herbicidal adjuvant or fertiliser. The process brings about significant improvements in spray drift control without the risk of overdosing with either adjuvant/fertiliser or pesticide/herbicide.
