摘要:
Improved methods and apparatuses for inserting pedicle screws in accordance with embodiments of the present invention include an image correction algorithm. In various embodiments, an original image of a region of interest of a patient including a pedicle is created with an X-ray emitter and an X-ray detector. Due to the X-ray emitter not being aligned orthogonal to the X-ray detector, the original image will be skewed. Using a known location and orientation of the X-ray detector, a location and orientation of the X-ray emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to properly insert a pedicle screw along the axis of the pedicle while viewing an accurate corrected image in real time
摘要:
Improved methods and apparatuses for imaging during medical procedures in accordance with various embodiments of the present invention include use of an image correction algorithm. In various embodiments, an original image of a region of interest where a medical procedure occurring along a particular axis will be performed is created with a beam emitter and a generally planar detector. Due to the emitter not being aligned orthogonal to the detector, the original image will be skewed. Using a known location and orientation of the detector, a location and orientation of the emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to perform the medical procedure while viewing an accurate corrected image in real-time.

摘要:
An aqueous and liquid cleansing composition comprises a fatty acid soap, a salt of a lauryl ether sulfate surfactant that is present in an amount that is at least 50% of the weight of the fatty acid soap, a betaine surfactant that is present in an amount that is at least 23% of the weight of the fatty acid soap, and at least 0.05% by weight of the composition of triclocarban. The lauryl ether sulfate and betaine surfactant in the specified amount in relation to the fatty acid soap amount keep the triclocarban from precipitating out of the composition.

Techniques are provided to start a virtual service node that is configured to provide network traffic services for one or more virtual machines. The virtual service node has at least one associated service profile comprising identifiers for corresponding service policies for network traffic services. The service policies identified in the at least one associated service profile are retrieved. A virtual machine is started with an associated virtual interface and a port profile is applied to the virtual interface, including information identifying the service profile. Information is provided to the virtual service node that informs the virtual service node of network parameters and assigned service profile of the virtual machine. Network traffic associated with the virtual machine is intercepted and redirected to the virtual service node. A virtual service data path is provided that enables dynamic service binding, virtual machine mobility support, and virtual service node chaining and/or clustering.
摘要:
A phototherapy apparatus for the treatment of skin disease is disclosed including: an at least partially hollow body element; a plurality of light emitting elements enclosed within the body element; and a plurality of elongated light transmitting elements, each of the light transmitting elements having a proximal end detachably affixed to the body element in proximity to one or more of the light emitting elements, and extending to an end distal the body element. For each of the elongated light transmitting elements, at least a portion of light incident from the light emitting elements onto the proximal end is directed through the light transmitting element and emitted from the distal end.

A phototherapy apparatus is disclosed including: a handpiece including a body member and a grip; a plurality of elongated light transmitting elements, each of the elements extending between a proximal end enclosed within the body member and a distal end located outside of and distal to the body member; an ultraviolet light source; a light collection element; and one or more optical coupling elements. The proximal ends of the light transmitting elements are located in close proximity to each other The light collection element is configured to collect at least a portion of the light emitted from the light source. The one or more optical coupling elements are configured to direct at least a portion of the collected light to the proximal ends of the light transmitting elements to couple at least portion of the collected light into the light transmitting elements The light coupled into each of the light transmitting elements is transmitted along the element and emitted from the distal end.
摘要:
The present invention relates to improved dispensers for a tablet containing or consisting of a dissolvable composition which, when contacted with water, will elute one or more chemical compounds to the water. More particularly the present invention relates to such an improved dispenser for a tablet which according to one aspect of the invention is particularly useful with, or forms a part of a device for the treatment of water, particularly a device useful in the purification of water.
