Abstract

Apparatus for annotation and navigation of electronic images comprising a handheld controller for use with a computer system. The controller comprises a microphone, voice dictation controls that generate commands to operate a digital audio recording and playback functions in the computer system, and image display controls to advance or back up through a series of images or files displayed in an image display unit of the computer system.

Claims

1. A handheld controller for controlling annotation and navigation of electronic images, for use with a computer system, said computer system being provided with at least one image display unit, random access memory, means for digital data storage, comprising:

finger operated image display controls for controlling display of images in said image display unit, said image display controls including

a first switch mechanism having neutral centered position, and being responsive to forward pressure to cause said first switch mechanism to generate a command to cause said computer system to advance through a series of image files displayed in said image display unit, said first switch being responsive to rearward pressure to cause said first switch mechanism to generate a command to cause said computer system to back up through a series of image files displayed in said image display unit, and

second and third switch mechanisms to generate additional commands to cause said computer system to perform additional functions to permit further study of a displayed image in said display unit;

a microphone for receiving audio dictation and converting audio signals to electrical signals;

a finger operated dictation control having a dictation switch mechanism located in said controller, said dictation switch mechanism being operable to generate commands for recording and playback of audio dictation received in said microphone, converted to said electrical signals, and digitally stored in said computer system; and

communication means for communicating commands generated by said image display controls and said dictation controls, and said electrical signals from said microphone, to said computer system.

2. A controller in accordance with claim 1, wherein said image display control and said dictation control have multiple functions, and wherein at least some of said functions of said image display control and said dictation control are both accomplished through commands generated by actuation of one or more of said first, second, third and dictation switch elements, the particular control function provided by a switch element or combination of switch elements being dependent on a mode of dictation or a mode of image display or a combination of modes of dictation and image display at the time of operation of said one or more switch elements.

3. A controller in accordance with claim 1, wherein said image display control and said dictation control comprise no more than six switch elements.

4. A controller in accordance with claim 3, wherein said image display control and said dictation control comprise no more than four switch elements.

5. A controller in accordance with claim 1, wherein said first switch mechanism is responsive to the amount of pressure applied thereto whereby lesser pressures applied thereto generate commands for advancing or backing up through image files at a slower rate, and greater pressures applied thereto generate commands for advancing or backing up through image files at a faster rate.

6. A controller in accordance with claim 1, wherein said first switch mechanism is a strain gauge.

7. A controller in accordance with claim 1, wherein said dictation switch mechanism comprises a trigger switch located for actuation with a forefinger of a user of said controller, and said first switch is located on an upper surface of said controller for actuation with a thumb of the user of said controller.

8. A controller in accordance with claim 1, wherein said communication means comprises an infrared transmitter provided in said controller and an infrared receiver associated with said computer system.

9. A controller in accordance with claim 1, wherein said second and third switch mechanisms are further operable to generate a command to cause said computer system to display a menu of available functional modes.

10. A controller in accordance with claim 1, wherein said second and third switch mechanisms are further operable to generate commands to control audio dictation functions in said computer system.

11. A handheld controller for controlling annotation and navigation of electronic medical images, for use with a computer system, said computer system being provided with at least one image display unit, random access memory, means for digital data storage, comprising:

finger operated image display controls for controlling serial display of different radiographic medical image files of a patient displayed in said image display unit, said image display controls including

a centered switch mechanism that has neutral centered position, and which is responsive to forward pressure to cause said centered switch mechanism to generate a command to cause said computer system to advance in serial order through a series of image files displayed in said image display unit, and which is responsive to rearward pressure to cause said centered switch mechanism to generate a command to cause said computer system to back up in serial order through a series of image files displayed in said image display unit, said centered switch mechanism being responsive to the amount of pressure applied thereto whereby lesser pressures applied thereto generate commands for advancing or backing up through image files at a slower rate, and greater pressures applied thereto generate commands for advancing or backing up through image files at a faster rate, and

left and right switch mechanisms located on left and right sides of said centered switch mechanism to generate additional commands to cause said computer system to perform additional functions to permit further study of a displayed image in said display unit;

a microphone for receiving audio dictation and converting audio signals to electrical signals;

a finger operated dictation control having a first switch mechanism located in said controller, said switch mechanism being operable to generate commands for recording and playback of audio dictation received in said microphone, converted to said electrical signals, and digitally stored in said computer system; and

wireless communication means for communicating commands generated by said image display controls and said dictation controls, and said electrical signals from said microphone, to said computer system.

12. A controller in accordance with claim 11, wherein said wireless said wireless communication means comprises an infrared transmitter provided in said controller and an infrared receiver associated with said computer system.

13. A controller in accordance with claim 12, wherein said left and right switch mechanisms further are operable to generate a command to cause said computer system to display a menu of available functional modes.

14. A controller in accordance with claim 12, wherein said left and right switch mechanisms are further operable to generate commands to control audio dictation functions in said computer system.

15. A controller in accordance with claim 11, wherein said image display control and said dictation control have multiple functions, and wherein at least some of said functions of said image display control and said dictation control are both accomplished through commands generated by actuation of one or more of said first, second, third and dictation switch elements, the particular control function provided by a switch element or combination of switch elements being dependent on a mode of dictation or a mode of image display or combination of modes of dictation and image display at the time of operation of said one or more switch elements.
