Abstract

A medical imaging system including a sound recording sub-system that records, digitizes and time-stamps at least one channel of sound related to time domain images produced by the medical imaging system in accordance with a system clock signal. The sound recording sub-system indexes or synchronizes the at least one channel of sound to events in the plurality of time domain images, which are acquired, digitized and time-stamped in accordance with the system clock signal. The time-stamped, digitized at least one channel of sound is memory-stored.

Claims

1. A medical imaging system, comprising:

a system clock for generating a synchronization signal;

a medical imaging sub-system that procures a plurality of time domain images of internal structure within a patient during a medical diagnostic procedure being performed on the patient and digitally converts the time domain images to digitized time domain image data; and

a sound recording sub-system that records, digitizes and time-stamps at least one channel of sound related to the time domain images in accordance with the synchronization signal, the sound recording sub-system indexing the at least one channel of sound to at least three events related to the medical diagnostic procedure or to operation of the imaging sub-system to split the at least one channel of sound, based on the events, into a plurality of digitized time-stamped audio data files which are synchronized with the time-stamped, digitized time domain image data.

2. The medical imaging system as set forth in claim 1, further comprising a memory for digitally storing the indexed, time-stamped audio data files.

3. The medical imaging system as set forth in claim 2, further comprising a playback sub-system that accesses and displays reconstructed images from the digitized time domain image data and synchronizes the playing of the time-stamped audio data files, based on the events.

4. The medical imaging system as set forth in claim 3, wherein the sound recording sub-system indexes the at least one channel of sound with a plurality of pieces of clinical information related to the patient and wherein the playback sub-system enables the access and playback of multiple pieces of audio information from the at least one channel of sound on a display showing a piece of clinical information related to the patient.

5. The medical imaging system as set forth in claim 1, wherein the imaging sub-system comprises an ultrasound imaging system.

6. The medical imaging system as set forth in claim 5, wherein the at least one channel of sound is digitized at 22 to 44.1 KHz and encoded in a wave compatible format.

7. The medical imaging system as set forth in claim 5, wherein the at least one channel of sound is comprises a Doppler audio signal.

8. The medical imaging system as set forth in claim 5, wherein the at least one channel of sound comprises ECG sounds.

9. The medical imaging system as set forth in claim 5, wherein the at least one channel of sound comprises heart sounds.

10. The medical imaging system as set forth in claim 5, wherein the at least one channel of sound comprises respiration sounds.

11. The medical imaging system as set forth in claim 1, wherein the at least one channel of sound includes dictation audio and wherein the medical imaging system further comprises:

a voice recognition subsystem that translates the dictation audio into typed text, and wherein said typed text is time-stamped for indexing and synchronization.

12. The medical imaging system as set forth in claim 1, wherein the sound recording sub-system indexes the at least one channel of sound with clinical information related to the patient.

13. The medical imaging system as set forth in claim 1, wherein the sound recording sub-system indexes the at least one channel of sound with a plurality of pieces of clinical information related to the patient.

14. The medical imaging system as set forth in claim 1, wherein an event includes:

start of exam;

change of imaging mode;

change of probe;

user actuation of a control device; and

end of exam.

15. A method for obtaining imaging and sound information during a medical diagnostic procedure, the method comprising:

performing the medical diagnostic procedure on a patient;

procuring a plurality of time domain images of internal structure within the patient during the medical diagnostic procedure;

digitizing the time-domain images, and time-stamping the digitized time domain images with a system synchronization signal;

receiving at least one channel of sound related to the time domain images;

digitizing and time-stamping the least one channel of sound with the system synchronization signal; and

indexing the at least one channel of sound to at least three events related to the medical diagnostic procedure or to the procurement of the plurality of time domain images to split the at least one channel of sound, based on the events, into a plurality of digitized time-stamped audio data files which are synchronized with the digitized time-stamped time domain images.

16. The method as set forth in claim 15, further comprising the steps of:

displaying the plurality of digitized time domain images; and

playing the audio data files based on the events synchronized with the display of the plurality of time domain images.

17. The method as set forth in claim 16, further comprising the step of indexing the audio clip data files with clinical information related to the patient based on time-stamping in accordance with the system synchronization signal.

18. The method as set forth in claim 16, further comprising the steps of:

indexing the audio data files with a plurality of pieces of clinical information related to the patient based on time-stamping in accordance with the system synchronization signal;

displaying a piece of clinical information related to the patient; and

enabling the access and playback of the audio data files indexed to the piece of clinical information being displayed upon request by a user.

19. The method as set forth in claim 15, wherein the step of procuring a plurality of time domain images of a patient comprises procuring a plurality of ultrasound images.

20. The method as set forth in claim 15, wherein the step of digitizing and time-stamping comprises digitizing the at least one channel of sound at 22 to 44.1 KHz, and wherein the computer readable file is wave compatible.

21. The method as set forth in claim 15, wherein the at least one channel of sound comprises a Doppler audio signal.

22. The method as set forth in claim 15, wherein the at least one channel of sound comprises ECG sounds.

23. The method as set forth in claim 15, wherein the at least one channel of sound comprises heart sounds.

24. The method as set forth in claim 15, wherein the at least one channel of sound comprises respiration sounds.

25. The method as set forth in claim 15, wherein the at least one channel of sound includes dictation audio and wherein the method further comprises the step of:

translating the dictation audio into a computer readable file having character data which is time-stamped in accordance with the system synchronization signal.

26. The method as set forth in claim 16, further comprising the step of indexing the audio data files with a plurality of pieces of clinical information related to the patient based on time-stamping in accordance with the system synchronization signal.
