Abstract
The disclosure relates to a Mobile Fluoroscopic Device consisting of a Mini-C Arm assembly containing a stepless collimating apparatus which is adjustable using pairs of linear translating, opaque to x-ray plates (2). Each pair of plates are operated by a drive mechanism including a motor (3), gears (4, 6), and racks (5) making it possible to increase or decrease the cross-sectional area of the x-ray beam relative to the x-ray sensor surface area.
Claims16
A mobile mini C-arm fluoroscopic/radiographic imaging device comprising:
- a x-ray beam generator;
- an image receptor;
- a curved structural support assembly;
- and
- a collimating apparatus configured to allow for user-controlled stepless adjustment of an x-ray beam size and shape through a continuous range to optimize a field of view at the image receptor, the collimating apparatus comprising:
- a first pair of plates, each of the first pair of plates coupled to a first rack;
- a second pair of plates, each of the second pair of plates coupled to a second rack;
- a first drive gear configured to interface with the first rack coupled to one of the first pair of plates and to rotate to linearly translate the first rack coupled to the one of the first pair of plates;
- a second drive gear configured to interface with the second rack coupled to one of the second pair of plates and to rotate to linearly translate the second rack coupled to the one of the second pair of plates;
- a first idler gear configured to interface with both the first rack coupled to the one of the first pair of plates and the first rack coupled to the other of the first pair of plates, wherein the translation of the first rack coupled to the one of the first pair of plates causes the first idler gear to rotate which, in turn, causes the first rack coupled to the other of the first pair of plates to translate such that the first pair of plates move closer together or farther apart from each other;
- and
- a second idler gear configured to interface with both the second rack coupled to the one of the second pair of plates and the second rack coupled to the other of the second pair of plates, wherein the translation of the second rack coupled to the one of the second pair of plates causes the second idler gear to rotate which, in turn, causes the second rack coupled to the other of the second pair of plates to translate such that the second pair of plates move closer together or farther apart from each other.
