Apparatus and method for detecting cancerous mass of breast via electromagnetic radiation by computer controlled emitter and detector of radiation with window and optional collimator and motor

A method of detecting an internal structure in an object, comprising:

• emitting a radiation beam, by at least one radiation beam emitter, each radiation beam along a propagation direction of emission for each of the at least one radiation beam emitter and with an energy intensity that has an initial numerical value,
• the object having a near side near the radiation beam emitter and a far side farther from the radiation beam emitter than the near side,
• the object having a near surface near the radiation beam emitter and a far surface farther from the radiation beam emitter than the near surface,
• detecting and measuring, by at least one radiation detector, the energy intensity of the radiation beam;
• supporting, by a first support structure, the at least one radiation beam emitter, the at least one radiation detector, in fixed place with respect to the object, the first support structure physically attached to the object and in fixed position with respect to the object,
• at least one first window fixed at a perpendicular direction to the propagating direction of emission at the near side, the at least first window having a near side which is closer to the radiation beam emitter, and a far side, which is farther from the radiation beam emitter as compared with the near side,
• wherein the at least first window is pressing against the near side of the object, causing that the near side of the object conforms in shape to the at least first window,
• wherein the radiation beam propagating along the propagating direction of emission is perpendicular to the near side of the at least first window, perpendicular to the far side of the at least first window, and perpendicular to the near side of the object that conformed to the far side of the at least first window which the at least first window configuration therefore provides normal incidence at both sides of the at least first window and normal incidence for the object,
• with an added collimator in front of the radiation detector, wherein the collimator is oriented along the propagation direction of emission, which defines a collimating direction, wherein the collimator selects radiation that travels only along the collimating direction which is along the propagation direction of the radiation beam, to enter the radiation detector along the collimating direction;
• performing, by a computer that is connected to the at least one the radiation beam emitter and the at least one radiation detector, the following sequence,
• 1) selecting and turning on one of the radiation beam emitters and the opposite radiation detector, which causes that a direction along a line of incidence is chosen among one of the propagating directions of emission of at least one of the radiation beam emitters,
• 2) emitting the radiation beam along the line of incidence and from the near side of the object,
• 3) measuring the radiation beam on the far side of the object, along the same line of incidence, repeating sequence 1 to 3 until all the directions along all lines of incidence are selected, when process stops;
• wherein the computer is configured for storing in the computer memory all the values from the radiation beam on the far side of the object and calculating using a co-ordinate system, the magnitudes of the measured radiations at step 3 for one or both the same line of incidence and/or along a plurality of different lines or sum over several different lines;
• wherein after calculation of all the measured radiations along all used lines of incidence and along one or more different lines, the computer is further configured to generate and display an image which is a visual display of the absorption along all used the lines of incidence and/or along one or more different lines, and moreover, that each image point is determined exclusively as the measurement along a particular the line of incidence and not as a calculation or comparison with other the lines of incidence.
