Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P) are tracked. A 4D mathematical model may be established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using non-rigid image registration between pre-operative and intra-operative images, the position of the target and/or other part(s) of the anatomical region may be determined.

Tracking of moving targets

Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P), are dynamically tracked. A 4D mathematical model is established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using fiducial-less non-rigid image registration between pre-operative DRRs and intra-operative x-ray images, the absolute position of the target and/or other part(s) of the anatomical region is determined. The cycle P is determined using motion sensors such as surface markers. The radiation beams are delivered using: 1) the results of non-rigid image registration; 2) the 4D model; and 3) the position in time within P.

Systems and methods for providing privacy settings for applications associated with a user profile are provided. Exemplary methods include receiving a request from a member of a web-based social network to install an application in association with a member profile, installing the requested application, providing privacy settings selections to control access to data associated with the installed application, receiving a privacy settings selection from the member, and displaying data associated with the application based on the privacy settings selection.

A patient positioning assembly is described. The patient positioning assembly including a plate member rotatably mounted on a base member, and an arm extending between a first end and a second end, wherein the first end is rotatably attached to the plate member. The patient positioning assembly further including a support device rotatably attached to the second end of the arm to support a patient thereon, with the support device is configured to move the patient in at least five degrees of freedom.

Systems and methods for tracking cardiac targets are disclosed. The cardiac targets may be tracked dynamically. The process may include registering a cardiac target at different phases of a cardiac cycle. Movement of the cardiac target can be determined by correlating respiratory motion and cardiac pumping motion. Radiation treatment can then be delivered to the cardiac target taking into account the movement of the cardiac target.

Cardiac target tracking

A robotic patient positioning assembly for therapeutic radiation treatment includes a robotic positioning device for moving and supporting the patient during treatment, a sensor system for detecting the position of the robotic positioning device, and a controller operatively connected with the sensor system for receiving position data of the robotic positioning device and operatively connected to the robotic positioning device for controlling the motions of the robotic positioning device. The controller is adapted for controlling the motion of the robotic positioning device in response to information representative of the position of the robotic positioning device received from the sensor system, so that the treatment target within a patient loaded on the robotic positioning device is properly aligned with a radiation source of a therapeutic radiation treatment system.

A method for automatic auction extension and user controlled standardized bid increment/decrement. The method is implemented in an electronic commerce exchange. The auction method implements automatic extension of an auction in response to bidding activity from auction participants. The method includes the step of setting an end time for concluding the auction. Bids are received from remote bidders via a distributed computer network. The received bids are analyzed to determine whether a predetermined number of bids are received within a predetermined time of the auction end time. If a greater number of bids are received within the predetermined time, the duration of the auction is automatically extended and a new auction end time is set. The auction participants are notified of the new auction end time. Standardized bid increments can be set defining a minimum amount at which a subsequent bid differs from a previous bid. Similarly, standardized bid decrements can be set defining a minimum amount at which a subsequent bid subsequent bid differs from a previous bid. A total number of possible extensions can be set defining a number of times the auction can be extended due to bidding activity. The settings can be changed dynamically during the auction by the auction operator/user.

An auction method for specifying catalog contents for packaging and pushing to an electronic auction. The auction method is implemented in an electronic commerce exchange. The auction method includes the steps of specifying catalog contents for packaging for an auction operation hosted on the electronic exchange. Initial terms for the sale of the contents are then specified. The auction is then automatically initiated using the previously specified contents and the previously specified terms. The auction proceeds with the receiving of bids for the contents from remote bidders. The bids are received via a distributed computing network into which the electronic commerce exchange is communicatively coupled. A winning bid is selected by determining a most competitive bid out of the bids received for the contents. A sale of the contents is then completed based upon the terms of the most competitive bid.

An auction method for implementing automatic bid status refresh and item attribute updates in an electronic exchange. The method includes the step of receiving update configuration information from remote bidders via a distributed computer network. The update configuration information includes a time interval for receiving bid status updates. An auction is conducted wherein bid information received from the remote bidders is compared to determine a bid status and wherein the bid status is used to determine the bid status updates for the remote bidders. The bid status includes information regarding the most competitive, or winning, bid and any associated terms. The bid status updates are disseminated to the remote bidders via the distributed computer network in accordance with the update configuration information. At the conclusion of the auction, an auction winner is designated in accordance with the latest most competitive bid of the bid status. The time interval of the update configuration information is user selected and can be adjusted dynamically during the auction. Remote bidders receive bid status updates in accordance with their specified time interval. Changes to the items and/or item attributes of the auction are also disseminated to the remote bidders via the distributed computer network in accordance with the time interval of the update configuration information.

A mechanism is described in which data from a first application running on a first computer is stored for access over a network by a second application running on a second computer. In one aspect, messages are periodically broadcast over the network to indicate that data has been stored for transfer. A list is displayed identifying computers that have broadcast messages regarding the transfer of data. In one aspect, the data is part of a file rather than an entire file.

An apparatus and method for optimizing a workspace of a radiation treatment delivery system. An optimized treatment plan is generated for delivering a dose of radiation to a volume of interest ('VOI') in a patient using fewer changes to a treatment plan parameter during delivery of the dose of radiation then available to a radiation treatment delivery system. The optimized treatment plan limits a number of adjustments to the treatment plan parameter during delivery of the dose of radiation. Prior to delivery, the optimized treatment plan is analyzed to determine whether a quality of the optimized treatment plan is acceptable.
