Abstract

DC60 (18/08/54) laser unit compatible device For determining the patient's organ position in computerized radiography It consists of a cross-shaped main structure with mounting wings and a support that secures two point laser units. Through a bar lens to make two linear beams form a criss-cross beam. Projected onto the patient's organs For use in determining the position Patient organs on radiography By computer tomography By this device in addition to supporting the set Laser and optics already Radiation filter set is also supported. And radiation size control unit as well For convenience in Installation and disassembly Laser unit support device For determining the patient's organ position in computerized radiography It consists of a cross-shaped main structure with mounting wings and a support that secures two point laser units.

Claims (4)

1. The device supports the laser unit. For positioning the patient's organs for radiography In computed tomography - the main structure (1) is formed into a cross-shaped rod with wings (2) as A number of components in the center of the main structure are recessed holes (3) with shaped holes. Squares (4) and V-grooves (5) are elements on the sides of the holes. - The radiation beam size control unit (6) is a round disc made of lead with a perforated hole corresponding to the shaped hole. The rectangles (4) are assembled into such holes. - The radiation filter unit (7) is molded from a metal material to look like a cone cut in the center of the concave V-groove with wings (8) connected from the V-groove. Where the wings are sized That is consistent and fit into the V-groove (5) of the main structure (1) On the other side of the main structure (1), there are a number of supports (9) connected, where such supports are formed as rods, assembled at right angles. A number of holes are drilled on the bar - the laser unit (12) is attached to the support (9), where the laser unit looks like a bar. The cylinder fits into the support sleeve. The non-supported place also includes a lens mounting hole. The bar (13) and the threaded nut fastening hole (11) on the other end of the lens are inserted into the hole (10), and near it there is a hole. For tightening the threaded nut (14) For fastening the threaded nut through the mounting hole. Rod lens (13) to keep the rod lens (13) from detaching from the support. 2. The device supports the laser unit. For positioning the patient's organs for radiography In computer X-ray according to claim 1, where the laser unit (12) has two sets, one Assembled into a vertical support The other assembly is horizontal. 3. The device supports the laser unit. For positioning the patient's organs for radiography In a computer X-ray machine according to claim 1, where a rod lens (13), mounted on the support sheath of the laser unit (12), converts the light from the barrel. From point light to line light, vertical and horizontal laser beams intersect. A laser image is formed on the patient's organ in a criss-cross shape for positioning the patient's organ. 4. The device supports the laser unit. For positioning the patient's organs for radiography In the computer X-ray machine according to claim 1, where the rod lens (13) can be rotated and angled. As needed To determine the position of the laser beam projected. By loosening the screw nut (11) and the nut (14)
