摘要： A method of secure file conversion is disclosed. The method includes storing a decrypted version of a previously encrypted file, the encryption and decryption occurring using public key infrastructure, in an allotted memory location of a memory for which read-only access to the stored decrypted file is provided. Next, the memory location is monitored for an attempt to access at least one memory location other than the allotted location. Finally, a file format of the stored decrypted file is converted, the conversion being aborted upon detecting attempt to access at least one memory location other than the allotted memory location. A converter is further disclosed.

摘要： Paths are determined for high intensity focused ultrasound. A subset of possible paths is selected for the application of high intensity focused ultrasound. Obstructions (e.g., bone or metal), tissue characteristics (e.g., organ or tissue sensitivity to heat or attenuation characteristic), distance, or another factor are used to select the scan lines for high intensity focused ultrasound. The selection may be aided by ultrasound imaging data, such as data representing a volume. The response from different regions is used to identify the tissue characteristics or obstructions. The factors may also be used to determine a dose (power) and/or frequency of the high intensity focused ultrasound.
