    摘要： Method and systems are disclosed for radiating a moving target inside a heart. The method includes acquiring sequential volumetric representations of an area of the heart and defining a target tissue region and/or a radiation sensitive structure region in 3D for a first of the representations. The target tissue region and/or radiation sensitive structure region are identified for another of the representations by an analysis of the area of the heart from the first representation and the other representation. Radiation beams to the target tissue region are fired in response to the identified target tissue region and/or radiation sensitive structure region from the other representation.

    摘要： Methods and apparatus create an attachment and a seal between two tubular members in a wellbore. An expandable assembly includes a packer and liner hanger to be expanded into a surrounding tubular. The packer can be a longitudinally corrugated packer and can have a sealing element disposed on an outer surface thereof. The liner hanger can include a plurality of formations extending outward along an outer surface of the liner hanger to form interspaces for longitudinal fluid flow between the formations. In operation, an expansion tool moves axially through an inner diameter of the expandable assembly to expand the liner hanger with a fluted expander and subsequently the packer with a substantially uniform outer diameter cone.

    摘要： Embodiments of the present invention relates to hydraulically actuated tools, which may be used to actuate a liner hanger assembly. In one embodiment, the present invention provides a hydraulic setting tool for use in wellbore operations. The setting tool includes a first tubular member and a second tubular member disposed around the outer diameter of the first tubular member. A piston is mechanically attached to an upper portion of the second tubular member and adapted to move axially in relation to the first tubular member. The piston acts to transmit a force to the second tubular member. A slip assembly is operatively connected to the second tubular member and the second tubular member transmits the force to the slip assembly thereby actuating the slip assembly.

    摘要： A machine learning system for evaluating at least one characteristic of myocardial tissue and its ablation or subset thereof, which includes a training mode and a production mode. The training mode is configured to train, assess and guide a computer and construct a transformation function to predict an anatomical, physiologic, electric, metabolomic, or genetic manifestation leading to alterations, including ablation, that predict and unknown structural or functional characteristic of myocardial tissue and a subsequent aberration that results in abnormal electrical signal and subsequently results in abnormal heart function. The production mode is programmed to use any transformational function to predict the unknown electroanatomic and metabolic characteristic that result in arrhythmia and abnormal myocardial function and guide subsequent ablation and elimination of arrhythmogenic foci.
