Abstract

An apparatus for digital colposcopy and videography comprises a digital imaging camera that is operably coupled to the optical path of the digital colposcope by means of a beam splitter so that a digital image of the cervico-vaginal tissue can be captured. The digital imaging camera and digital colposcope are mounted to one end of an articulating arm of the apparatus. A digital processing means is operably connected to the digital imaging camera to create a digital image. The digital processing means is housed in a stand of the assembly.

Claims

1. A self-contained cervical cancer detection apparatus for digital imaging of a cervico-vaginal tissue, comprising:

a. an assembly having an extension arm assembly and a stand assembly,

b. a digital-imaging colposcope mounted to the extension arm assembly, said digital imaging colposcope having a colposcopic head, a digital camera for producing more than one digital image of the cervico-vaginal tissue, and a frame grabber for selecting one of the more than one digital images of the digital images,

c. digital processing means operable to enhance a digital image, the digital processing means being housed in the stand assembly, and

d. a video monitor mounted to the stand assembly whereby a series of digital images of the cervico-vaginal image may be viewed by an operator of the cervical cancer detection apparatus and an optimum image created through the digital processing means while viewing the enhanced image on the video monitor.

2. The apparatus according to claim 1, wherein the digital processing means comprises a computer software and hardware system.

3. The apparatus according to claim 1, wherein the video monitor is a flat panel video monitor.

4. The apparatus according to claim 1, wherein the video monitor is swingably mounted to the stand assembly for displaying the digital image.

5. The apparatus according to claim 1, wherein the video monitor is telescopically mounted to the base of the assembly for permitting the video monitor to be adjusted to a proper height for viewing by a user.

6. The apparatus according to claim 1 wherein the apparatus is mobile.

7. The apparatus according to claim 6, wherein the stand assembly includes rollers to permit the apparatus to be mobile.

8. The apparatus according to claim 1, wherein the digital-imaging colposcope comprises a digital camera operably coupled to a colposcope including a beam splitter.

9. The apparatus according to claim 3, wherein the digital camera is configured to create color digital images.
