Abstract
Abstract An equipment for retinal and choroidal angiography comprises means (1) for the illumination of the ocular fundus and means (23,25,27,29) for displaying and/or recording the image of the ocular fundus. Means (19) for image intensification, receive the image information originating from the ocular fundus and send an intensified image to said means for display and/or recording.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
117 words
Equipment for displaying and/or recording images of an object, or part of an object, or of a tissue, organs or parts of a human or animal being, comprising in combination: - means (1; 1A, 1B, 1C; 105; 201) for generating an electromagnetic radiation to be sent to the object to be observed; and - conveying means (15, 17; 115; 205) for sending the image of said object to displaying and/or recording means (23, 27; 107, 113; 221, 223); characterized by: - means of image intensification (19; 109; 219), combined to said displaying and/or recording means (23, 27; 107, 113; 221, 223) in order to transmit to said displaying and/or recording means an intensified image of said object.
Claim 2
Dependent Claim
81 words
Equipment for endoscopy comprising an endoscopy (101), a light source (105) for illuminating the organs to be displayed, first conveying means (102) for sending the light emitted by said source to the organs to be illuminated, second conveying means (115) for sending the image of said organs to displaying and/or recording means (107); characterized by means of image intensification (209), combined to said displaying and/or recording means, to send to said displaying and/or recording means an intensified image of said organs.
Claim 3
Dependent Claim
72 words
Equipment for retinal and choroidal angiography and similar, comprising means (1; 1A, 1B, 1C) for generating an electromagnetic radiation, which illuminates the ocular fundus, conveying means (15, 17) for sending the image of the ocular fundus to displaying and/or recording means (23, 27); characterized by: means for image intensification (19), combined to said displaying and/or recording means, to send an intensified image of the ocular fundus to said displaying and/or recording means.
Claim 4
Dependent Claim

Claim 11
Dependent Claim
45 words
The equipment as claimed in claim 10, comprising a plurality of light-emitting diodes (LEDs) (1A, 1B, 1C), each of which emits at an operating wavelength of the equipment, the light emitted from one of said diodes being selectively sent toward the fundus of the object.
Claim 12
Dependent Claim
35 words
The equipment as claimed in one or more of the preceding claims, comprising a television camera (23; 221) for the capture of the images and possibly a monitor (27; 113, 223) for displaying the image.

Claim 15
Independent Claim
85 words
A method for examining and/or recording images of an object, or part of an object, of a tissue, of an organ or part of an organ of a human or animal being, comprising the steps of: - sending to said object to be examined a beam of electromagnetic radiation; - sending the image of said object to displaying and/or recording means; - displaying and/or recording said image; characterized in that the image of said object is intensified and the intensified image is diaplayed and/or recorded.
Claim 16
Independent Claim
79 words
A method of performing examinations by retinal and choroidal angiography and similar, comprising the phases of sending toward the fundus of the eye a beam of electromagnetic radiation at a predetermined wavelength, capturing the image of the fundus of the eye, and displaying and/or recording said image on suitable means of display and/or of recording, characterized in that the image of the fundus of the eye is intensified before being sent to said means of display and/or of recording.
Claim 17
Independent Claim
81 words
A method for performing an endoscopic examination, comprising the steps of: - introducing an endoscope in the cavity or in the organ to be examined; - sending into the cavity or the organ to be examined a beam of electromagnetic radiation; - detecting the image coming from said cavity or said organ; - displaying and/or recording said image on suitable displaying and/or recording means; characterized in that the detected image is intensified before sending it to said displaying and/or recording means.
