摘要:
FIELD: medicine.SUBSTANCE: invention refers to medical equipment, namely to X-ray apparatuses. An apparatus comprises X-ray emitters, X-ray image recorders, a first fastener for keeping the X-ray emitter facing the X-ray image recorder, a second fastener for keeping the first fastener rotating about a first axis, a first drive, a third seat for keeping the second fastener rotating about a second axis perpendicular to the second axis, a second drive for make the second fastener rotating about the second fastener and a drive control for drive speed adjustment of the first drive and the second drive. The drive control is integrated to control the drives so that to observe the following conditions: (A) one of the fasteners rotates in a specified mode at angular speed a·sin(t), while the other fastener rotates at angular speed b·cos(t), the X-ray emitters and image recorders moves in a circular or elliptical orbit, wherein a and b is peak angular speed of the matched fastener in the specified mode, t is time, and (B) one of the fasteners is found in a period of start-up for a period of time ΔT1, from a position at an initial angle φ1 and at angular speed f(t), while the other fastener is found in a period of start-up for a period of time ΔT2, from a position at an initial angle φ2 and at angular speed g(t) with performing an equation system, wherein ΔT2 is a rotation length from a position at an angle φ1, φ2 to a position at an angle to achieve the specified mode at rotation at angular speed a·sin(t) and b·cos(t) respectively.EFFECT: use of the invention enables higher safety and speed of precessional motion, lower vibration accompanying system transfer into the specified mode and following achievement of the specified mode.2 cl, 9 dwgИзобретение относится к медицинской технике, а именно к рентгеновским устройствам. Устройство содержит средства излучения рентгеновских лучей, регистрации рентгеновских изображений, первое средство крепления для удержания средства излучения
