Abstract
Abstract A method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies that involves the steps of providing a movable source of light external to the copier, a movable light diffuser locatable between the source of light and the copying surface of the copier and providing apparatus for adjusting the light illuminance at the copying surface of the copier. The method then involves the steps of locating the medical x-ray negative on the copying surface of the copier and illuminating the medical x-ray negative with light which passes through the movable light diffuser with the illuminance at the copying surface of the copier being between the predetermined limits of about 950 foot candles and about 1,425 foot candles while making a copy of the medical x-ray negative with the copier.

A method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies comprising the steps of: providing an electrostatic type copier having a copying surface; providing a movable source of light external to said electrostatic type copier and movable light diffusing means locatable between said external movable source of light and the copying surface of said electrostatic type copier; providing means for adjusting the light illuminance at the copying surface of said electrostatic copier from light provided from said movable light source after said light passes through said movable light diffusing means; adjusting the light illuminance at the copying surface of said electrostatic type copier between the predetermined limits of about 950 foot candles and about 1,425 foot candles; locating a medical x-ray negative on the copying surface of said electrostatic type copier; and illuminating said medical x-ray negative with light from said movable source of light which passes through said movable light diffusing means with the illuminance at the copying surface of said copier being between said predetermined limits of about 950 foot candles and about 1,425 foot candles while making a copy of said medical x-ray negative with said electrostatic type copier.
Claim 2
Independent Claim
197 words
A method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies comprising the steps of: providing an electrostatic type copier having a copying surface; providing a movable source of light external to said electrostatic type copier and movable light diffusing means locatable between said external movable source of light and the copying surface of said electrostatic type copier; providing means for adjusting the light illuminance at the copying surface of said electrostatic copier from light provided from said movable light source after said light passes through said movable light diffusing means; adjusting the light illuminance at the copying surface of said electrostatic type copier between the predetermined limits of about 950 foot candles and about 1,425 foot candles; locating a medical x-ray negative on the copying surface of said electrostatic type copier; and illuminating said medical x-ray negative with light from said movable source of light which passes through said movable light diffusing means with the illuminance at the copying surface of said copier being between said predetermined limits of about 950 foot candles and about 1,425 foot candles while making a copy of said medical x-ray negative with said electrostatic type copier.
Claim 3
Dependent Claim
121 words
The method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies of claim 1 further comprising the steps of: providing means for moving said movable source of light and said movable light diffusing means between at least two positions with one of said positions permitting said electrostatic type copier to be used to copy medical x-ray negatives and another of said positions permitting said electrostatic type copier to be used in a conventional copying manner without medical x-ray negatives; and moving said movable source of light and said movable light diffusing means into position to permit said electrostatic type copier to be used to copy medical x-ray negatives when it is desired to copy medical x-ray negatives.
Claim 4
Dependent Claim
64 words
The method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies of claim 1 further comprising the steps of providing means for transmitting copies of said medical x-ray negatives made by said electrostatic type copier to a remote location and transmitting the copies of said medical x-ray negatives to the remote location through the use of said copy transmitting means.
Claim 5
Dependent Claim
43 words
The method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies of claim 3 wherein said step of providing means for transmitting copies of said medical x-ray negatives comprises the step of providing digitizing means and providing a MODEM.
Claim 6
Dependent Claim
59 words
The method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies of claim 4 wherein said step of transmitting copies of said medical x-ray negatives comprises the step of using said digitizing means to digitize copies of medical x-ray negatives and transmitting digitized copies of said medical x-ray negatives through the use of said MODEM.
Claim 7
Dependent Claim
58 words
The method for using a conventional electrostatic type copier to copy medical x-ray negative transparencies of claim 5 further comprising the steps of providing storage means for storing said digitized copies of said medical x-ray negatives and storing said digitized copies of said medical x-ray negatives prior to transmitting said digitized copies through the use of said MODEM.
