An apparatus and method for processing ultrasound data is provided. The apparatus includes an interface operatively connected to a memory, a programmable single instruction multiple data processor (or two symmetric processors), a source of acoustic data (such as a data bus) and a system bus. The memory stores data from the processor, ultrasound data from the source, and data from the system bus. The processor has direct access to the memory. Alternatively, the system bus has direct access to the memory. The interface device translates logically addressed ultrasound data to physically addressed ultrasound data for storage in a memory. The translation is the same for data from both the processor and the source for at least a portion of a range of addresses. The memory stores both ultrasound data and various of: beamformer control data, instruction data for the processor, display text plane information, control plane data, and a table of memory addresses. One peripheral connects to the ultrasound apparatus. An interface adapter, powered from the ultrasound apparatus, translates information transferred between the peripheral and the ultrasound apparatus. The adapter connects non-standard peripherals to various standard interfaces on the ultrasound apparatus. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring to FIG.
1, a preferred embodiment of an ultrasound system according to the present invention is generally shown at 20.
The flexible system 20 is described below, first with reference to the structure of the system 20, and then with a reference to several examples of the operation of the system 20.
Other structures and uses of the system 20 are intended to be covered by the claims, which define the invention.
Structure General The system 20 includes a transducer 22, a beamformer 24 and a data processing system 26.
The system 20 also includes various peripherals, such as a hard disk drive 28, a removable media device 30 (e.
g.
a magneto optical disk drive), a local area network 32, a display 34, a speaker 36, a physio module 38, a microphone 40, a user interface 42 and other external peripherals 44.
The other external peripherals include video or audio recording and playback devices, printers, cameras, and other devices.
The peripherals may include analog or digital video or audio inputs and outputs.
The physio module 38 preferably includes an EGG, phono, pulse, respiration and one or more auxiliary DC-coupled input channels (e.
g.
DC-A, DC-B, DC-C and DC-D).
Preferably, the data processing system 26 controls operation of the peripherals.
The system 20 may include no peripherals or any subset of these peripherals.
The data processing system 26 includes a centralized memory for storing microprocessor code and data (software or algorithms) and concurrently storing various subsystem data.
The subsystem data includes acoustic image data, video data, audio data, physio data, waveform data, text and graphics data, and other subsystem data.
As used herein, the term ultrasound or acoustic image data encompasses data derived from the transmission of acoustic energy and used to generate an image or audio output in one or more of various modes, such as B-mode, M-mode, color Doppler mode (velocity, variance or energy), spectral Doppler mode (spectrum, derived waveform or audio) and other modes
