Abstract

A method and apparatus for breast examination. A pair of spaced, transparent plates are provided between which a female breast may be gently compressed and flattened. A beam of light from a movable light source is directed through the plates and flattened breast, and the light source may be moved to sequentially illuminate substantially the entire breast between the plates. The beam of light may be view through the plates and breast to permit visual detection of areas of breast tissue having lesser transparency and which may be suggestive of tumor growth.

Claims

1. Apparatus for the examination of the female breast for tumors or the like, comprising a pair of spaced plates transparent to visible light;

means for supporting the plates relative to each other and permitting the plates to be moved toward and away from one another to enable the breast to be captured and gently compressed and flattened between the plates; and

a source of visible light positionable exteriorly of the plates for producing a narrow beam of light directable through the plates and flattened breast, said source being movable with respect to the plates generally normal to the direction of said beam to enable sequential illumination of substantially the entire breast captured between the plates.

2. The apparatus of claim 1 wherein said light source includes means for varying the diameter of the narrow beam of light.

3. The apparatus of claim 1 including means for varying the wavelength of the light beam.

4. The apparatus of claim 1 wherein the visible light is substantially monochromatic.

5. The apparatus of claim 1 wherein said means for supporting the plates relative to each other includes means maintaining confronting surfaces of the plates parallel.

6. The apparatus of claim 5 including means gently urging the plates apart.

10. The apparatus of claim 1 wherein the light source includes a manually supportable barrel open at its upper end, a source of light within the barrel, and means carried by the barrel for varying the cross-sectional area of the light beam emitted by the light source.

11. The apparatus of claim 10 including means for varying the wavelength of the emitted light.

7. Apparatus for the examination of the female breast for tumors or the like, comprising a pair of spaced plates transparent to visible light, means for supporting the plates relative to each other and permitting the plates to be moved toward and away from one another to enable the breast to be captured and gently compressed and flattened between the plates, and a source of visible light positionable exteriorly of the plates for producing a narrow beam of light directable through the plates and flattened breast, said source being movable with respect to the plates generally normal to the direction of the beam to enable illumination of substantially the entire breast between the plates, at least one of said plates including visible, spaced, parallel scribe lines thereacross, the spacing between adjacent lines being substantially the same as the diameter of the light beam.

8. The apparatus of claim 7 including means for varying the diameter of the light beam.

9. Apparatus for the examination of the female breast for tumors or the like, comprising a pair of spaced plates transparent to visible light, means for supporting the plates relative to each other and permitting the plates to be moved toward and away from one another to enable the breast to be captured and gently compressed and flattened between the plates, a source of visible light positionable exteriorly of the plates for producing a narrow beam of light directable through the plates and flattened breast, and screening means positionable to screen the examiner'"'"'s eyes from the light beam at edges of the flattened breast.

12. Apparatus for the examination of the female breast for tumors or the like, comprising

a. a pair of spaced, generally parallel plates transparent to light, the plates having aligned edges gently concaved to fit snugly against the human chest wall in the vicinity of the breasts;

b. means supporting the plates relative to each other and permitting at least one of the plates to move toward and away from the other plate to enable the breast to be captured and gently compressed and flattened between the plates;

c. light absorbing means positionable against exposed edges of the compressed, flattened breast received between the plates and capable of substantially preventing the escape of light from the breast edges;

d. a source of visible light positionable exteriorly of the plates for producing a beam of light directable through the plates and breast and generally normal to the plane of the plates, the light source including means permitting the diameter of the beam of light to be manually adjusted.

13. The apparatus of claim 12 wherein at least one of the plates includes visible indicia thereon defining a path for the beam of light to follow, the pathway being configured to cause illumination of substantially the entire breast section when the light beam is caused to follow the pathway from one end thereof to the other.

14. The apparatus of claim 12 including means permitting at least one of the plates to tilt upwardly about an axis generally parallel to the concavely curved edge of the plate.

15. A method for simply and harmlessly detecting tumors or the like in the female breast comprising

compressing and flattening the breast between a pair of plates transparent to visible light, passing a beam of light from a movable light source in a direction normal to and through the plates and breast between the plates, moving the light source so as to illuminate substantially all portions of the breast tissue captured between the plates, and viewing the beam of light through the plates and breast tissue to detect areas of breast tissue having lesser transparency and which may be suggestive of tumor growth.

16. The method of claim 15 including the step of varying the diameter of the light beam as the beam is viewed through the plates and breast.
