Abstract

A mobile digital radiography system of a type including a mobile x-ray source; a mobile computer, the computer having a display for radiographic images and related information; a digital radiography detector, the detector and x-ray source in communication with and under control of the computer, means operatively associated with the computer for sending and receiving data concerning a patient, such data including diagnostic results, diagnostic images and requests for additional services, to and from separate image archiving and information systems; means operatively associated with the computer for comparing data from separate hospital image archiving and radiology information systems from a prior examination of a patient with data from a current examination of a patient using the mobile digital radiography system; and means operatively associated with the computer for aiding bedside interpretation of a patient'"'"'s condition in view of the comparing of data from prior and current examinations.

Claims

1. A mobile digital radiography system comprising:

a mobile x-ray source for emitting x-rays through a portion of a patient'"'"'s body;

a mobile computer having a display to display radiographic images and related information;

a digital radiography detector responsive to the emitted x-rays, the detector and x-ray source in communication with and under control of the computer;

means operatively associated with the computer for sending and receiving medical data concerning a patient;

means operatively associated with the computer for comparing medical data from two or more archiving and information systems of a prior examination of the patient with medical data from a current examination of the patient using the mobile digital radiography system; and

means operatively associated with the computer for aiding bedside interpretation of a patient'"'"'s condition in view of the comparing of the medical data from the prior and current examinations.

2. The mobile digital radiography system of claim 1, further comprising a housing adapted to be held in a hand of an operator of the digital radiography system, the housing enclosing the computer, the display, the means for receiving data, the means for comparing data and the means for aiding bedside interpretation.

3. The mobile digital radiography system of claim 1, wherein the means for aiding bedside interpretation includes functionality for automatic processing of diagnostic images and presentation of results of the processing on the display.

4. The mobile digital radiography system of claim 3, wherein the functionality for automatic processing includes features for adjusting brightness, contrast and sharpness of images presented on the display.

5. The mobile digital radiography system of claim 3, wherein the functionality for automatic processing includes preset visualization settings for life support line visualizations.

6. The mobile digital radiography system of claim 3, wherein the functionality for automatic processing includes features for pneumothorax enhancement.

7. The mobile digital radiography system of claim 3, wherein the functionality for automatic processing includes features for computer assisted diagnosis, such as catheter placements.

8. The mobile digital radiography system of claim 1, wherein the means for aiding bedside interpretation includes interactive functionality to facilitate report generation.

9. The mobile digital radiography system of claim 8, wherein the interactive functionality includes feature for inputs to a structured report.

10. The mobile digital radiography system of claim 9, wherein the inputs are actuated by voice.

11. The mobile digital radiography system of claim 9, wherein the inputs are actuated by touch-screen features on the display.

12. A method for operating a mobile digital radiography system of a type including a mobile x-ray source for emitting x-rays through a portion of a patient'"'"'s body, a mobile computer having a display to display radiographic images and related information, and a digital radiography detector responsive to the emitted x-rays, the detector and x-ray source being in communication with and under control of the mobile computer, comprising:

receiving and sending medical data associated with the patient, such data including diagnostic results, diagnostic images and requests for additional services, from and to separate image archiving and radiology information systems;

comparing data from separate image archiving and information systems from a prior examination of a patient with data from a current examination of the patient using the mobile digital radiography system; and

aiding bedside interpretation of a patient'"'"'s condition in view of the comparing of data from prior and current examinations.

13. The method according to claim 12, wherein the step of aiding bedside interpretation includes automatic processing of diagnostic images and presenting of results of the processing on the display.

14. The method of claim 13, wherein the automatic processing includes adjusting brightness, contrast and sharpness of images presented on the display.

15. The method of claim 13, wherein the automatic processing includes presetting visualization settings for life support line visualizations.

16. The method of claim 13, wherein the automatic processing includes enhancing the patient'"'"'s pneumothorax.

17. The method of claim 13, wherein the automatic processing includes features for computer assisted diagnosis, such as catheter placements.

18. The method of claim 12, wherein the step of aiding bedside interpretation includes interactive functionality to facilitate report generation.

19. The method of claim 18, wherein the interactive functionality includes features for inputs to a structured report.

20. The method of claim 19, wherein the inputs are actuated by voice.

21. The method of claim 19, wherein the inputs are actuated by touch-screen features on the display.

22. The method of claim 12 wherein receiving and sending data concerning a patient comprises transmitting data over a wireless interface.

23. The method of claim 12 wherein the digital radiography detector comprises a wireless communication interface.

24. A mobile digital radiography system comprising:

a mobile x-ray source for emitting x-rays through a portion of a patient'"'"'s body;

a mobile computer having a display to display radiographic images and related medical information;

a digital radiography detector responsive to the emitted x-rays, the detector and x-ray source in communication with and under control of the mobile computer;

a communication link operatively associated with the mobile computer for accessing medical data from a current examination of the patient;

a communication link operatively associated with the mobile computer for accessing medical data from at least one prior examination of the patient from two or more medical databases;

wherein the mobile computer comprises a processor for comparing the medical data from the at least one prior examination with the medical data from the current examination; and

wherein the mobile computer comprises functions for providing bedside interpretation of a patient'"'"'s condition based on the comparing of the medical data.
