  • Patent number: 11511132
    Abstract: Systems and methods for tracking a target volume, e.g., tumor, in real-time during radiation treatment are provided. The system includes a memory to store a pre-acquired 3D image of the anatomy of interest in a first reference frame and a processor, operative coupled with the memory, to receive, from an ultrasound probe, a set-up ultrasound image of the anatomy of interest in a second reference frame. The processor further to establish a transformation between the first and second reference frames by registering the set-up ultrasound image with the pre-acquired 3D image and receive, from the ultrasound probe, an intrafraction ultrasound image of the anatomy of interest. The processor further to register the intrafraction ultrasound image with the set-up ultrasound image and track motion of the anatomy of interest based on the registered intrafraction ultrasound image.

  • Publication number: 20140151297
    Abstract: In a reverse osmosis fluid purification system, an input fluid is received at an input of the purification system, and a fluid purification run cycle is performed on the input fluid. The fluid purification cycle includes pumping the input fluid through a membrane with a pump at a first pressure and first flow rate to generate product fluid and waste fluid. The product fluid is provided to an external system and the waste fluid is provided to a drain port. The membrane is then rinsed after performing the fluid purification run cycle by providing the input fluid to the pump and pumping the input fluid through the membrane at a second pressure less than the first pressure and a second flow rate greater than the first flow rate for a predetermined period of time.

  • Patent number: 7953204
    Abstract: 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.

  • Publication number: 20070071168
    Abstract: 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.

  • Patent number: 7166852
    Abstract: A wireless treatment target positioning system for therapeutic radiation treatment includes a patient positioning system and a treatment target locating system. The treatment target locating system includes a room beam coordinate system and a localizing system. The room beam coordinate system includes devices for generating laser beams intersecting at a single point that is spatially coincident with an iso-center of the treatment system. The localizing system includes a movable reference object and a localizer for detecting and determining the position of the movable reference object. A method of positioning a treatment target to the iso-center of the treatment system includes a simulation process and real treatment positioning process. The simulation process includes positioning the treatment target to an iso-center of a simulation system and marking intersection points where laser beams intersect with an exterior of the patient's body.
