Abstract
The utility model provides a CT machine apparatus capable of adjusting central position of ray bundle, comprising a radiation tube, a scanning beam limiting device, a detection device, a machine frame, a rotating plate and a rotating shaft. The machine frame is a support member for the main body, the machine frame is composed of a frame with a bottom and two end frames, which can make the apparatus in a stable operation status all the time. The detection device is fixed on the machine frame, the rotating plate is fixed below the detection device, and the rotating shaft is fixed at one side at lower of the detection device. The radiation tube as a radioactive source is fixed in the center on the detection device, and the scanning beam limiting device s fixed at lower of the radiation for limitting the scaning ray beam. The apparatus of the utility model has a simple structure, is convenient in operation and use, and the limitation and adjustment to the ray beam can be implentmented by the scanning beam limiting device. Limitted scan can be selected by the scanning beam limiting device for the subject needing local CT examination, thereby reducing unnecessary quantity of radiation to the least.
Description
Technical field:
This utility model relates to the medical inspection device of Non-Destructive Testing human body diseases, relates in particular to the adjustable CT machine in beam center.
Background technology:
The CT machine of prior art relates generally to by radioactive source, detector, DAS imaging system, display system, bed body and rotary apparatus and forms.Radioactive source wherein and detection system are installed on the frame that can sway, and person under inspection's bracing or strutting arrangement is installed in the body, and can move along the axis direction of system.When radioactive source sends beam, when arriving detector, just can produce a signal through the person under inspection, through the conversion of DAS imaging system with manifest, set up stratiform bidimensional cross-section image.The fan angle of ray, fan-beam center and fan-beam width can not change the variation that energy or fabric width take place with person under inspection's figure, and this has just caused shadow surface expansion, and irradiation dose increases, and certainly will cause unnecessary damages to the person under inspection.
The utility model content:
The purpose of this utility model is, overcome the deficiencies in the prior art part, provide a kind of beam center adjustable CT machine, the angular range that the restriction ray penetrates, make beam only be radiated at the zone of organ to be checked, form with rapid scanning is finished CT scan, the amount of radiation that reduces the person under inspection as much as possible and born.
The adjustable CT machine in beam described in the utility model center includes radiation bulb, scanning beam-defining clipper, checkout gear, frame, swivel plate and rotating shaft and forms.Said frame is a body supports part of the present utility model, and said frame includes bottom framework and two end frames are formed, and bottom framework and end frame can make this utility model be in stable duty all the time.Frame is provided with checkout gear of the present utility model, below said checkout gear, is provided with swivel plate, in the bottom of checkout gear one side, is provided with rotating shaft.Middle position on checkout gear is provided with the radiation bulb as radioactive source, below said radiation bulb, is provided with scanning beam-defining clipper, and the ray wire harness that scans is limited.
The adjustable CT machine in beam described in the utility model center, overall structure is simple, and is easy for operation, can realize restriction and adjusting to beam by scanning beam-defining clipper.Need the person under inspection of CT examination for the part, can select to use scanning beam-defining clipper to carry out restricted scanning, reduce unnecessary amount of radiation as much as possible.
Description of drawings:
Accompanying drawing 1 is the structural representation of the adjustable CT machine in beam described in the utility model center.1-radiation bulb 2-scanning beam-defining clipper 3-checkout gear 4-frame 5-swivel plate 6-rotating shaft
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: the adjustable CT machine in beam described in the utility model center includes radiation bulb 1, scanning beam-defining clipper 2, checkout gear 3, frame 4, swivel plate 5 and rotating shaft 6 and forms.Said frame 4 is body supports parts of the present utility model, and said frame 4 includes bottom framework and two end frames are formed, and the common frame of forming 4 of bottom framework and end frame can make this utility model be in stable duty all the time.Frame 4 is provided with checkout gear 3 of the present utility model, below said checkout gear 3, is provided with swivel plate 5, in the bottom of checkout gear 3 side, is provided with rotating shaft 6.Middle position on checkout gear 3 is provided with the radiation bulb 1 as radioactive source, below said radiation bulb 1, is provided with scanning beam-defining clipper 2, and the ray wire harness that scans is limited.The adjustable CT machine in beam described in the utility model center, overall structure is simple, and is easy for operation, can realize restriction and adjusting to beam by scanning beam-defining clipper 2.Need the person under inspection of CT examination for the part, can select to use scanning beam-defining clipper 2 to carry out restricted scanning, reduce unnecessary amount of radiation as much as possible.
