Abstract

A system which includes at least one ultrasound data collection device which is programmable to carry out a specific ultrasound procedure. The resulting ultrasound data is transmitted via a local server to the internet and from there to a web database server which processes the raw ultrasound data and provides application-specific information, such as a three-dimensional model, which can be used for diagnostic interpretation of the body part imaged by the ultrasound.

Claims

1. A system for generating application-specific medical ultrasound information, comprising:

an ultrasound data collection assembly to carry out an ultrasound scan of a selected part of a human body of a patient at a given location by an operator and to produce raw, unprocessed ultrasound information therefrom but not an ultrasound image;

a data transmission system for transmitting the raw, unprocessed ultrasound information obtained by the assembly to a processing location physically remote from the data collection assembly location, wherein the ultrasound information is transmitted to the remote processing location without proceeding through a local processor at the site of the data collection assembly;

a processor at the remote location for processing the transmitted information sufficiently to produce a medical analysis of the selected body part therefrom, wherein the medical analysis is then transmitted back to a medical practitioner associated with the patient, wherein the medical analysis includes information suitable for use in the treatment of the patient; and

a memory structure for storing program information for control of at least one ultrasound procedure to be carried out by the data collection assembly and for storing information produced from the ultrasound procedure for each patient, including a data link between the memory structure and the data collection assembly.

2. A system of claim 1, wherein the data collection assembly includes an ultrasound transducer and an associated transducer control assembly for moving the transducer through a specified angle in a plurality of scan lines, with each successive scan line being separated by a selected angle.

3. A system of claim 2, wherein the scan lines cover approximately 360°

, and each scan line is separated by approximately 1.5°

.

4. A system of claim 2, wherein the selected angle is 120°

.

5. A system of claim 1, including a system database server, where said processing of the ultrasound information occurs and which includes said memory structure, wherein the ultrasound information is transmitted from the ultrasound data collection assembly to the database server via the internet, the system database server being on the internet.

6. A system of claim 5, wherein communication between the data collection assembly and the server/database includes an infrared communication link.

7. A system of claim 5, wherein the memory structure includes a plurality of application-specific ultrasound programs for selective downloading to the data collection assembly.

8. A system of claim 5, wherein the data transmission system includes a thin server with an internet browser located with the data collection assembly, wherein the thin server provides a visual image of the selected part of the body, so that an operator can properly position the ultrasound assembly on the human body to carry out the selected ultrasound procedure.

9. A system of claim 5, including a camera for taking a visual image of the patient, and wherein said visual image information is transmitted to the database server, along with the ultrasound information, to identify the patient.

10. A system of claim 5, including an audio recording assembly for recording audio information associated with the ultrasound procedure, wherein the audio information is transmitted to the database server, along with the ultrasound information.

11. A system of claim 10, including a voice print system to identify the patient from the audio information.

12. A system of claim 5, wherein the database server includes means for accumulating information from successive ultrasound examinations of a given patient, thereby maintaining a patient history for said given patient.

13. A system of claim 1, wherein the ultrasound information is processed to produce a three-dimensional image of the human body part.

14. A system of claim 1, including at least one accelerometer to indicate movement of the ultrasound assembly or patient during the ultrasound procedure.

15. A system of claim 1, including a plurality of ultrasound transducers and associated transducer control assemblies, to provide an increased field of view of the body part being imaged.

16. A system of claim 15, wherein the plurality of ultrasound transducers are controlled in such a manner that the ultrasound signals issuing therefrom do not interfere with each other.

17. A system of claim 1, wherein the transmitted information is sufficiently processed by the processor that an ultrasound skilled interpreter is not necessary for the medical analysis.

18. A system of claim 1, wherein the processor produces a medical analysis from the transmitted information.

19. A method for generating application-specific ultrasound information, comprising:

scanning a portion of the body of a human patient with ultrasound signals and receiving the reflected ultrasound signals therefrom, the received ultrasound signals being in the form of raw, unprocessed ultrasound information;

transmitting said raw, unprocessed ultrasound information to an internet-based database server without the ultrasound information proceeding through a local processor at the site of scanning;

processing the information provided to the database server to produce an application-specific medical analysis of the said body part; and

transmitting the medical analysis to a medical practitioner associated with the patient, wherein the medical analysis includes information suitable for use in the treatment of the patient.

20. A method of claim 19, including the step of downloading an application-specific program from the database server for carrying out an application-specific scanning of said portion of the body.

21. A method of claim 20, wherein the step of scanning the body part includes transmitting a plurality of ultrasound signals in a sequence of individual planes, the planes being separated by a selected angle of rotation.

22. A method of claim 21, wherein the scanning covers 360°

.

23. A method of claim 19, including the step of accumulating the ultrasound information from successive examinations of a given patient, thereby maintaining a patient history on said patient.

24. A method of claim 19, including the step of comparing the processed information with information results from another diagnostic tool, to produce a clinical evaluation of the effectiveness of the ultrasound analysis.
