Abstract
Винахід стосується конструкції багатосенсорних цифрових приймачів рентгенівського випромінювання на базі оптоелектронних перетворювачів з полями зору, що частково перекриваються, й до конструкції комп'ютерних пірамідально-променевих рентгенівських томографів, оснащених такими приймачами. Ці томографи призначені для обстеження людей і тварин. Заявлені багатосенсорний цифровий приймач рентгенівського випромінювання і пірамідально-променевий рентгенівський томограф, що містить такий приймач. Багатосенсорний цифровий приймач рентгенівського випромінювання має світлонепроникний корпус із декількох розташованих під тупим кутом секцій із плоско-угнутою рентгенопрозорою стінкою й закріплені за її плоскими частинами секції рентгенооптичного перетворювача й світлонепроникної й рентгенонепроникної перегородки. У перегородці закріплені формувачі фрагментарних аналогових відеосигналів, кожний з яких має фільтр залишкового рентгенівського випромінювання, багатолінзовий об'єктив й оптоелектронний перетворювач. Поля зору сусідніх формувачів усередині й з боків секцій зазначеної перегородки частково перекриваються. Електричні виходи оптоелектронних перетворювачів підключені до блока формування цілісних цифрових відеосигналів і далі до системи формування рентгенологічних картин, відповідних до заданих зрізів, і комп'ютерного томосинтезу. Пірамідально-променевий рентгенівський томограф має нерухому вертикально орієнтовану стійку; поворотну П-подібну опору, на горизонтальних консольних виступах якої опозитно закріплені кероване джерело рентгенівського випромінювання з коліматором для формування пірамідального рентгенівського пучка й запропонований приймач рентгенівського випромінювання; горизонтальний рентгенопрозорий стіл для розміщення обстежуваного суб'єкта в зазорі між джерелом і приймачем рентгенівського випромінювання; блок керування зворотно-обертальним рухом П-подібної опори в заданому секторі окружності й систему формування рентгенологічних картин, відповідних до заданих зрізів, і комп'ютерного томосинтезу. Технічний результат: вирівнювання яскравості рентгенівських картин по всій робочій площі, одержання томограми задовільної якості, зменшення матеріалоємності і енерговитратності томографа.The invention relates to the construction of multi-sensor digital X-ray receivers based on partially overlapping optoelectronic converters and to the design of computer pyramidal X-ray tomographs equipped with such receivers. These tomographs are intended for examination of humans and animals. A multi-sensor digital X-ray transceiver and a pyramidal X-ray tomograph containing such a receiver are claimed. The multi-sensor digital X-ray transceiver has a light-proof housing with several sections at an obtuse angle with a flat-curved X-ray wall and fixed on its flat parts of the X-ray transducer section and a light-proof and X-ray transducer. Shapes of fragmentary analog video signals are fixed in the partition, each of which has a residual x-ray filter, a multi-lens and an optoelectronic converter. The fields of view of adjacent shapers inside and on the sides of the sections of the specified partition partially overlap. The electrical outputs of the optoelectronic converters are connected to the unit of formation of integral digital video signals and further to the system of formation of radiological pictures corresponding to the given sections, and computer tomosynthesis. The pyramidal X-ray tomograph has a fixed vertically oriented rack; a rotatable U-shaped support, the horizontal console projections of which have a controllable x-ray source with a collimator for forming a pyramidal x-ray beam and the proposed X-ray receiver; a horizontal X-ray table for placing the subject under examination in the gap between the source and the X-ray receiver; control unit of the rotary motion of the U-shaped support in a given sector of the circle and the system of formation of radiological pictures corresponding to the given sections and computer tomosynthesis. EFFECT: alignment of brightness of x-ray images throughout the working area, obtaining a tomogram of satisfactory quality, reduction of material intensity and energy consumption of the tomograph.
