Abstract
A transparency viewing device including a faceplate adapted for mounting at least one transparency having a particular density at a portion thereof, a source of back illumination for the transparency and a controller which varies the chromaticity of the back illumination based on the particular density. Preferably, the controller varies the chromaticity based on the chromaticity of the transparency. Additionally or alternatively, the controller locally varies the chromaticity.
Claims
AMENDED CLAIMS
[received by the International Bureau on 12 June 1997 (12.06.97);
original claim 44 amended; remaining claims unchanged (1 page)]
35. A method in accordance with any of claims 32-34, wherein illuminating comprises illuminating the eye using ambient lighting
36. A method in accordance with any of claims 32-34, comprising determining a direction of gaze of the eye, wherein controlling the pupil size comprises controlling the pupil size responsive to the direction of gaze
37. A method of scanning a mammogram comprising:
back-illuminating only a portion of a mammogram corresponding to an outer layer of a breast; and
subsequently back-illuminating only a second outer layer p onion of the breast.
38. A method in accordance with claim 37, wherein subsequently comprises serially scanning the entire outer layer of the breast in the mammograin.
39. A method in accordance with claim 37, wherein back-illuminating comprises graded back-illuminating, such that denser image pans of said portion receive greater amounts cf back- illumination than less dense pans thereof 40. A method in accordance with any of claims 37-39, comprising detecting the outer layer of a breast in a mammogram.
41. A method in accordance with claim 40, wherein detecting comprises detecting the outer layer based on a density analysts of the mammogram.
42. A method w accordance with claim 40, wherein detecting comprises detecting the outer layer based on a textural analysis of the mammogram.
43. A method in accordance with claim 40, wherein detecting comprises detecting the outer layer based on feature recognition of the breast orientation and location.
44. A method of automatic scanning of an x-ray transparency of soft tissue disposed near a bone, comprising:
masking a low density portion of the transparency corresponding to the bone: and sequentially back-illuminating portions containing substantially only soft tissue on at least one side of the masked bone.
