Electronic method and system that improves efficiencies for rendering diagnosis of radiology procedures

Abstract

An electronic method and system for improving radiologists' efficiencies when viewing radiology procedures and rendering diagnosis in a manner that emulates current methods and apparatus. The method of the present invention includes reviewing electronic radiology images and reports contained in a patient's digital master folder (an information object invented to manage the patient's radiology information), comparing images from the current procedure to specific images from prior procedures in a specified order, and dictating the procedure's diagnosis into the digital master folder. The apparatus of the present invention includes a flat panel monitor for the viewing and manipulation of digital master folders, a dictation trackball device for manual and voice enabled operation and navigation of the system, and multiple high-resolution computer monitors functioning as a “light-box” for the viewing of radiology images.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 60/168,106 filed Nov. 30, 1999. The subject matter of this application is incorporated by this reference.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a method and apparatus for improving radiologists' efficiencies when viewing radiology procedures and rendering diagnosis.

[0004] 2. General Background of the Invention

[0005] Typically, every radiology office uses a dictating machine for the preparation of reports, a stack of master folders that contain patient information, and a light box, roto viewer, or like device for viewing radiology images. These images can include for example x-rays, ultrasound, magnetic resonance imaging (MRI), computer tomography, nuclear medicine images and the like.

[0006] The manual file folder system employed by radiologists and radiology departments is inefficient and cumbersome.

BRIEF SUMMARY OF THE INVENTION

[0007] The present invention provides an electronic method of improving the efficiency of a radiologist and of a radiology department.

[0008] With the present invention, a plurality of computer monitors are provided for displaying various images. At least one of the monitors simulates a radiology “light box”, roto viewer, or like device for displaying electronic radiology images.

[0009] At least one of the monitors is used to display a digital graphical representation of a patient's folder, namely a digital master folder.

[0010] A hyperlink is used to open the report and to open different “pages” of the patient's master folder.

[0011] In one embodiment, a voice activated command can be used to open the patient's master folder or to open “pages” of the patient's folder.

[0012] In another embodiment, a track ball device such as a computer mouse can be used to open the patient's master folder or “pages” contained within the folder.

[0013] In another embodiment, the radiologist/user is provided with a combination microphone/track ball device that enables the radiologist or user to open the patient's master folder or components thereof using either voice activated commands or the track ball device. A touch screen device hyperlink can also be used to open a patient's folder or report.

DETAILED DESCRIPTION OF THE INVENTION

[0028] FIG. 1 shows a digital representation of a patient folder designated generally by the numeral 10. Patient folder 10 shows two hyperlinks 11, 12. At the top center of the folder 10, a header 17 indicates that this folder can, for example, relate to an ultrasound. The folder could relate to their radiology procedures. By clicking on the ultrasound hyperlink, the window shown in FIG. 1 is opened providing a report display area 13 to be filled with the report information in text form as dictated by a radiologist.

[0029] When a radiologist double clicks on the report hyperlink 12 in FIG. 1, the screen in FIG. 2 is displayed which is the report screen 14 containing patient information and the substance of the report. Audio hyperlink 15 can be double clicked using the computer mouse in order to actually hear the report. When a user double clicks on the hyperlink 15 in FIG. 2, the display in FIG. 3 is shown on the screen having a graphical display for the audio.

[0030] When the radiologist double clicks on the ultrasound header 17 in FIG. 1, the screen provided in FIG. 4 has a modality subfolder 18 having a hyperlink 19. When the radiologist uses the computer mouse to double click on the exam hyperlink in FIG. 4, actual radiology images as shown in FIG. 5 are displayed.

[0031] In FIG. 5, a left computer monitor 20 and a right computer monitor 21 are shown. In FIG. 5, a “twelve up” configuration is shown in each of the monitors 20, 21. In FIG. 6, a “four up” configuration is shown in each of the monitors 20, 21. In FIG. 7, a cine mode is shown for each of the monitors 20, 21. In the cine mode, sets of images are grouped and maintained in that grouping on a selected screen 20 or 21. FIG. 8 is a screen capture image that shows a cine set display.

[0032] FIGS. 9-12 show the use of the method and apparatus of the present invention to display full size radiology images, namely one image per screen 20, 21. In FIG. 9, as an example, image 31 is a left image, current PA for a patient. The right image in FIG. 9 is an image that is a current lateral for the patient. To the left hand side in the screen capture of FIG. 9, a roto viewer 22 is also shown. The roto viewer in FIG. 9 is comprised of two columns of boxes, each column containing a set of windows, each window can be designated by the numeral 25. The windows 25 can be scrolled to display various radiology images as further shown in FIGS. 9 and 10.

[0033] In FIGS. 9 and 10, the upper left window box of roto viewer 22 is designated by the numeral 23. The upper right window box is designated by the numeral 24. The screen captures of FIGS. 9 and 10 illustrate examples of radiology images that can be displayed using the method and apparatus of the present invention.

[0034] As shown in FIG. 10, the roto viewer 22 can include different groups of images in each of the window boxes 23, 24, 25 or 26. In FIG. 10, the window 23 contains those images which are displayed in the left hand computer monitor 20. The window box 24 of roto viewer 22 contains images which are displayed in the right hand monitor 21 in FIG. 10. Other images can be contained in other window boxes of the roto viewer 22 as shown in FIG. 10, just below window boxes 23, 24. Each of these images 33, 34 appear in the roto viewer window boxes 23, 24. The roto viewer 22 can be moved about the screen by dragging it.

[0035] In FIG. 11, the zoom feature of the present invention is illustrated. Each of the screens 20, 21 display a zoomed image. The monitor 20 displays image 36. The monitor 21 displays image 39. At the lower left hand corner of each of the screens 20, 21, there is provided a picture in a picture display. This picture in a picture display includes the smaller picture 35 showing a chest x-ray as an example. The viewing area 37 represents that portion of the chest x-ray 35 that is to be displayed in zoom format as image 36 in FIG. 11. Similarly, the monitor 21 displays at its lower left hand corner a picture in picture 38 having viewing area 40 that designates the zoom area of the chest x-ray 38. The image 39 is that portion of the image contained within viewing area 40 and which has been enlarged to fill substantially all of screen 21.

[0036] FIG. 12 illustrates monitors 20, 21 with the roto viewer 22 removed.

[0037] In FIG. 13, the group of windows 27, 28, 29 and 30 represent different cine sets or groups of images that have been purposely grouped together by the radiologist. Each of the windows 27-30 can be moved about within the roto viewer to move the displayed images around the screens 20, 21.
