DIFFRACTIVE ANALYZER OF PATIENT TISSUE
An x-ray diffractometer may perform 3D-analysis of collagen tissue of a patient (a human or another animal). The diffractometer includes an oblong housing that may be hinged and that contains an x-ray projector and an x-ray receiver. The analyzed tissue, such as the external ear and skin of a patient, is accommodated between the x-ray projector and the x-ray receiver. The x-ray projector directs an x-ray micro-beam at the patient's tissue. The receiver contains a movable two-dimensional x-ray detector that detects the x-ray micro-beam passed through the analyzed tissue and detects x-rays scattered or diffracted by the analyzed tissue.
1 . A diffractometer system comprising:
an x-ray source including an x-ray projector that projects an x-ray beam;
an x-ray receiver including an array of x-ray sensors positioned to detect x-rays from the x-ray beam, wherein patient tissue to be analyzed can be accommodated between the x-ray source and the x-ray receiver; and
one or more telescoping structures on at least one of the x-ray source and the x-ray receiver, each telescoping structure extending to and fixing the patient tissue in place during an x-ray examination process.
2 . The diffractometer system of claim 1 , further comprising a computer system connected to the x-ray projector and the x-ray receiver, wherein the computer system is configured to control the x-ray projector and the x-ray receiver, process, store, and display data received from the x-ray receiver, perform 3-D diffractometric structural analysis, and calculate parameters of a three-dimensional reciprocal lattice of collagen in the patient tissue.
3 . The diffractometer system of claim 1 , wherein the x-ray projector comprises a radiation source and a beam conditioner forming the x-ray beam, the radiation source operating in continuous mode, and the beam conditioner including at least one monochromator, an x-ray collimating device, and an x-ray focusing device.
4 . The diffractometer system of claim 1 , wherein the patient tissue includes an external ear of a patient, and each of the telescoping structures presses against a skin surface of the external ear to hold the patient tissue in place for the x-ray examination process.
5 . The diffractometer system of claim 4 , where at least one of the telescoping structures further comprises a pressure sensor, the pressure sensor measuring force or compression applied to the external ear.
6 . The diffractometer system of claim 1 , wherein the x-ray source and the x-ray receiver are sealed to hold a vacuum or an inert gas and are equipped with windows through which the x-ray projector projects the x-ray beam and the x-ray receiver receives the x-rays.
7 . The diffractometer system of claim 1 , wherein the array of x-ray sensors is in a protection container that is vacuumed or filled with an inert gas.
8 . The diffractometer system of claim 1 , further comprising a swivel joint that connects the x-ray source to the x-ray receiver and permits rotation of the x-ray receiver relative to the x-ray source.
9 . The diffractometer system of claim 1 , wherein the x-ray receiver further comprises:
a first mechanism connected to move the array of x-ray sensors in a first direction toward or away from the x-ray source; and
a second mechanism coupled to excite vibrations of the array of x-ray sensors in a second direction that is transverse to the first direction.
10 . The diffractometer system of claim 9 , where the second mechanism is coupled to excite one or more types of transverse vibrations selected from a group consisting of fluctuations only in an equatorial direction perpendicular to the first direction, fluctuations in a meridional direction perpendicular to the first direction and to the equatorial direction, and fluctuations in both the equatorial and meridional directions simultaneously.
11 . The diffractometer system of claim 1 , wherein the x-ray projector comprises a radiation source selected from a group consisting of an x-ray tube and an x-ray laser.
12 . The diffractometer system of claim 1 , further comprising a tripod including a motorized positioning mechanism coupled to move and orient the x-ray source and the x-ray receiver.
13 . The diffractometer system of claim 12 , wherein the motorized positioning mechanism comprises at least one of a ball-screw motion transmission and a combination of a feed screw shaft that is driven to rotate by a position-controllable electric motor and a slide member that is held in thread-engagement with the feed screw shaft as well as using a step motor.
14 . The diffractometer system of claim 1 , wherein the x-ray projector further comprises a Kratki or Montel mirror collimator.
15 . The diffractometer system of claim 1 , further comprising a visible-light laser providing a light beam that is parallel to the x-ray beam.
16 . The diffractometer system of claim 1 , further comprising an autonomous power source based on electric accumulators and batteries.
17 . The diffractometer system of claim 16 , wherein the autonomous power source is an automotive electrical system.
18 . The diffractometer system of claim 1 , further comprising:
a telescoping arm attached to the x-ray source and the x-ray receiver and to a wall or a ceiling of a room; and
mechanisms and motors coupled to move the telescoping arm.
