  • Patent number: 8290985
    Abstract: Techniques for reconstructing a target hierarchy tree structure from profiling data of a computer system according to a predefined relational model, so as to obtain profiling information of a certain selected node. The predefined relational model is defined in advance according to a hierarchy tree structure of the profiling data, and is stored in an external storage system. The hierarchy tree structures can be constructed dynamically as required, thus the occupied amount of a memory can be seduced and users can view the profiling data freely.

  • Publication number: 20120010541
    Abstract: Therapy methods using pulsed cavitational ultrasound therapy can include the subprocesses of initiation, maintenance, therapy, and feedback of the histotripsy process, which involves the creation and maintenance of ensembles of microbubbles and the use of feedback in order to optimize the process based on observed spatial-temporal bubble cloud dynamics. The methods provide for the subdivision or erosion of tissue, liquification of tissue, and/or the enhanced delivery of therapeutic agents. Various feedback mechanisms allow variation of ultrasound parameters and provide control over the pulsed cavitational process, permitting the process to be tuned for a number of applications. Such applications can include specific tissue erosion, bulk tissue homogenization, and delivery of therapeutic agents across barriers.

  • Publication number: 20110067624
    Abstract: A cavitational ultrasound (e.g., Histotripsy) gel phantom and cavitational ultrasound testing system are provided that may include any of a number of features. One feature of the phantom and system is that it can allow for instant visual feedback on the efficacy and dosage of a Histotripsy transducer. The changes in the gel phantom can be visualized with the naked eye without having to wait for histology. The changes in the gel phantom can also be visualized with a camera, with ultrasound imaging, or with microscopy. In various embodiments, the phantom includes indicators such as carbon particles, dye-encapsulated beads, and red blood cells. Methods associated with use of the cavitational ultrasound gel phantom and testing system are also covered.

  • Patent number: 7699139
    Abstract: A surround for supporting a diaphragm used to create acoustic waves includes a rib section extending away from the diaphragm and a membrane section that is supported by the rib section. The membrane section has a thickness in a direction substantially normal to opposing top and bottom surfaces of the membrane section which is substantially thinner than a thickness of the rib section in a direction substantially normal to opposing top and bottom surfaces of the rib section. A restoring force returning the diaphragm to a home position is contributed to more due to deformation of the rib section than to deformation of the membrane section.
