Abstract
Abstract An inspection system using penetrating radiation wherein pixels corresponding to transmitted radiation which has been attenuated to at least a predetermined level are displayed in a first color. Pixels which correspond to radiation which has been backscattered to a least predetermined level are displayed in a second color, and pixels which correspond to the remainder of the transmitted radiation are displayed in a third color. Additionally, the brightness of the color of each pixel is controlled in dependence on how far above or below the predetermined level the detected transmitted or scattered signal is.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, after an object has been illuminated with penetrating radiation, receiving radiation which corresponds to a first type of interaction with said object and radiation which corresponds to a second type of interaction with said object, displaying pixels which correspond to at least a first presettable level of said first type of interaction in a fist predetermined single color, and displaying pixels which correspond to at least a second presettable level of said second type of interaction in a second, predetermined single color.
Claim 2
Independent Claim
101 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, after an object has been illuminated with penetrating radiation, receiving radiation which corresponds to a first type of interaction with said object and radiation which corresponds to a second type of interaction with said object, displaying pixels which correspond to at least a first presettable level of said first type of interaction in a fist predetermined single color, and displaying pixels which correspond to at least a second presettable level of said second type of interaction in a second, predetermined single color.
Claim 3
Dependent Claim
44 words
The method of claim 1 wherein pixels which correspond to both at least said firs presettable level of said first type of interaction and at least said second presettable level of said second type of interaction as displayed in said second, predetermined single color.
Claim 4
Dependent Claim
33 words
The method of claim 1 wherein said first type of interaction is the attenuation of radiation by said object and said second type of interaction is the backscattering of radiation by said object.
Claim 5
Dependent Claim
36 words
The method of claim 3 further including the step of controlling the brightness of said first and second colors depending on the magnitude of the received radiation corresponding to said first and second types of interaction.
Claim 6
Independent Claim
92 words
An apparatus for displaying information resulting from the inspection of an object with penetrating radiation, comprising: means for illuminating an object with penetrating radiation, means for receiving radiation which is transmitted through said object, means for receiving radiation which is backscattered from said object, means for displaying pixels which correspond to at least a first presettable level of attenuation of the transmitted radiation in a first predetermined single color, and means for displaying pixels which correspond to at least a second presettable level of backscattered radiation in a second predetermined single color.
Claim 7
Independent Claim
92 words
An apparatus for displaying information resulting from the inspection of an object with penetrating radiation, comprising: means for illuminating an object with penetrating radiation, means for receiving radiation which is transmitted through said object, means for receiving radiation which is backscattered from said object, means for displaying pixels which correspond to at least a first presettable level of attenuation of the transmitted radiation in a first predetermined single color, and means for displaying pixels which correspond to at least a second presettable level of backscattered radiation in a second predetermined single color.
Claim 8
Dependent Claim
33 words
The apparatus of claim 5, further including: means for displaying pixels which correspond to transmitted radiation which is attenuated less than said first presettable level of attenuation in a third predetermined single color.
Claim 9
Independent Claim
122 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, after an object has been illuminated with penetrating radiation, receiving radiation which corresponds to a first type of interaction with said object and radiation which corresponds to a second type of interaction with said object, displaying pixels which correspond to at least a first presettable level of said first type of interaction in a first predetermined single color, and displaying pixels which correspond to at least a second presettable level of said second type of interaction in a second, predetermined single color, and displaying pixels which correspond to less than one of said first and second levels in a third predetermined single color.
Claim 10
Independent Claim
122 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, after an object has been illuminated with penetrating radiation, receiving radiation which corresponds to a first type of interaction with said object and radiation which corresponds to a second type of interaction with said object, displaying pixels which correspond to at least a first presettable level of said first type of interaction in a first predetermined single color, and displaying pixels which correspond to at least a second presettable level of said second type of interaction in a second, predetermined single color, and displaying pixels which correspond to less than one of said first and second levels in a third predetermined single color.
Claim 11
Independent Claim
92 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, illuminating an object with penetrating radiation, after said radiation interacts with said object, receiving radiation which is transmitted through said object and radiation which is backscattered from said object, displaying pixels which correspond to at least a first presettable level of attenuation of the transmitted radiation in a first predetermined single color, and displaying pixels which correspond to at least a second presettable level of backscattered radiation in a second predetermined single color.
Claim 12
Independent Claim
92 words
A method of displaying information resulting from the inspection of an object with penetrating radiation, comprising the steps of, illuminating an object with penetrating radiation, after said radiation interacts with said object, receiving radiation which is transmitted through said object and radiation which is backscattered from said object, displaying pixels which correspond to at least a first presettable level of attenuation of the transmitted radiation in a first predetermined single color, and displaying pixels which correspond to at least a second presettable level of backscattered radiation in a second predetermined single color.
Claim 13
Dependent Claim
33 words

Claim 14
Dependent Claim
64 words
The method of claim 8 wherein the brightness of said first color is controlled in dependence on how far above said first presettable level of attenuation, the attenuation of said transmitted radiation which is received is, and wherein the brightness of said second color is controlled in dependence on how far above said second presettable level of backscattered radiation, the received backscattered radiation is.
Claim 15
Dependent Claim
64 words
The method of claim 9 wherein the brightness of said first color is controlled in dependence on how far above said first presettable level of attenuation, the attenuation of said transmitted radiation which is received is, and wherein the brightness of said second color is controlled in dependence on how far above said second presettable level of backscattered radiation, the received backscattered radiation is.
