An acceleration sensor (10) is attached to a collimator (12) and detects an acceleration of the collimator (12), and a speed calculation unit that calculates the speed of the collimator 12 on a basis of the acceleration detected by the acceleration sensor (10). When the speed of the collimator (12) exceeds a setting speed that is set in advance, a lifting or lowering of an arm (13) is stopped by attaching a permanent electromagnet (42) to a stopper plate (43). In addition, a warning message as a warning indication is displayed on a display unit, and a warning sound as a warning indication is generated from a speaker. Accordingly, damage to an apparatus is prevented.

Versatile, multimode radiographic systems and methods utilize portable energy emitters and radiation-tracking detectors. The x-ray emitter may include a digital camera and, optionally, a thermal imaging camera to provide for fluoroscopic, digital, and infrared thermal imagery of a patient for the purpose of aiding diagnostic, surgical, and non-surgical interventions. The emitter may cooperative with an inventive x-ray capture stage that automatically pivots, orients and aligns itself with the emitter to maximize exposure quality and safety. The combined system uses less power, corrects for any skew or perspective in the emission, allows the subject to remain in place, and allows the surgeon’s workflow to continue uninterrupted.

The present disclosure relates to a collimator for radiation generating apparatus, attached to a radiation generating apparatus, the collimator comprising: a frame fixed to the radiation generating apparatus and formed in a ring shape; and a shielding adjustment part provided with a plurality of shielding wings, one end of the shielding wings being hinged to the frame such that, when rotated, the other end of the shielding wings enters into a center of the frame, and the each one end of the shielding wings being disposed to be spaced apart on the frame, wherein the shielding wing is made of a radiation shielding metal. Accordingly, it is possible to easily adjust the diameter of radiation field made in a circular shape.

A computed tomography machine suitable for interventional procedures provides partial scans displaced about the patient away from the physician position to substantially reduce Compton scattering received by the physician. A modeling of patient dose accounting for the presence of shielding, different physician characteristics, patient positions, and probe position may be accomplished to affect a trade-off between these various factors optimized for interventional or similar procedures where a nonpatient must be close to the scanner during operation.

A radiation shield cover for covering a radiation shield of an X-ray system, the cover comprising cover sides; a cover bottom at the bottom of the cover sides configured to prevent contact of the radiation shield with a patient; a connection mechanism for connecting the cover to a radiation detector and/or a radiation source, and/or the radiation shield of the X-ray system; and a deployment mechanism configured to retract and/or extend the shield cover when the radiation shield retracts and/or extends, or thereafter.

The present disclosure provides systems and methods for create a scanning pencil beam of x-rays and the air cooling of the system. The system has an enclosure with an x-ray beam source disposed therein. An x-ray wheel having or holding an x-ray attenuating ring is disposed proximate to an end of the enclosure and is configured and disposed to rotate the x-ray attenuating ring and form a scanning pencil beam. The system has at least one air inlet and air outlet and at least one air moving device configured and disposed to move air through the air inlet and the air outlet and to air cool the x-ray system.

The invention is generally directed to a sterile surgical drape designed to provide a sterile barrier with a self-contained, expandable sterile pocket. The sterile surgical drape includes a pocket sized and shaped to accommodate the C-arm of an X-ray machine. The pocket spans the width of the operative site and includes an elastic band along a top edge to ensure that the pocket does not drop below the sterile field when not in use. In this way, the pocket is maintained around the C-arm and the sterile field is preserved during use. The surgical drape can optionally include an adhesive antimicrobial strip configured with an elongated length. The surgical drape can further optionally include one or more pouches sized and shaped to retain surgical instruments or tools.

Apparatus for x-ray CT scanning of an object comprises an x-ray generator (1) mounted on a first support (3) on an outer ring (4) and an x-ray detector (2) mounted on a second support (10) on an inner ring (11), and a drive mechanism arranged to rotate the outer and inner rings (4, 11). The outer and inner rings have a first common axis of rotation and the diameter of the outer ring (4) is greater than the diameter of the inner ring (11). The first and second supports (3, 10) are positioned diametrically opposite each other with the second support (10) on the far side of the inner ring (11) with respect to the position of the outer ring (4). The inner surface of the outer ring (4) and the outer surface of the inner ring (11) are formed with teeth, and the drive mechanism includes a gearing arrangement connecting the outer and inner rings (4, 11). The gearing arrangement comprises first and second toothed rotary gears (14, 16) fixed so as to rotate together about a second common axis of rotation, the first rotary gear (14) having a greater diameter than the second rotary gear (16). The first rotary gear (14) interengages with the teeth of the outer ring (4) and the second rotary gear (16) interengages with the teeth of the inner ring (11) via a third toothed rotary gear or a toothed drive belt (18). The ratio of the number of teeth on the outer and inner rings (4, 11) are the same as the ratio of the number of teeth on the first and second rotary gears (14, 16) so that the outer and inner rings (4, 11) rotate at substantially the same angular speed in the same direction, whereby x-ray radiation emitted by the x-ray generator (1) is directed towards the x-ray detector (2) whilst the first and second supports (3, 10), on which the x-ray generator (1) and x-ray detector (2) are respectively mounted, are moving along respective first and second annular concentric paths defined by the outer and inner rings (4, 11).

A portable x-ray device for producing x-rays may include a housing; an exposure device enclosed by the housing to generate x-rays; a slide switch connected to the exposure device being movable between a first position and a second position; a first trigger to activate the exposure device when the slide switch is in the first position being positioned on a first side of the housing; a second trigger to activate the exposure device when the slide switch is in the second position being positioned on a second opposed side of the housing.
