The quality of ping-based ultrasound imaging is dependent on the accuracy of information describing the precise acoustic position of transmitting and receiving transducer elements. Improving the quality of transducer element position data can substantially improve the quality of ping-based ultrasound images, particularly those obtained using a multiple aperture ultrasound imaging probe, i.e., a probe with a total aperture greater than any anticipated maximum coherent aperture width. Various systems and methods for calibrating element position data for a probe are described.

Calibration of multiple aperture ultrasound probes

A technique for managing process state information involves pushing process state information from the kernel space to the user space in the event of an application crash and generating a core file at the user level instead of at the kernel level. Handling the process state information at the user level instead of at the kernel level provides more flexibility in the generation and management of a core file as compared to systems that use kernel code to generate and manage the core file. A core dump application at the user level can be programmed to forward the core file to another system that has permanent storage capacity available. Additionally, the core dump application can be programmed to compress the process state information and/or to extract only certain information from the process state information while generating the core file.

Managing process state information in an operating system environment

A programmable non-volatile memory device includes block switching logic that enables device-level translation rules to be changed. The device-level translation rules map the external addresses received by the flash memory device to the internal addresses of the programmable non-volatile memory device. Because the device-level translation rules are changeable, the physical location in the programmable non-volatile memory device to which an external address maps can be changed in a manner that is transparent to off-device operations. By allowing device-level translation rules to be changed, block management functions can be accomplished within the programmable non-volatile memory device itself.
