Detailed description of the invention
Core of the present invention is to provide a kind of scanning means of medical detector, can improve correction efficiency, the unnecessary radiation that minimizing operating personnel and patient are subject to.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the perspective view of scanning means provided by the present invention in a kind of detailed description of the invention; The longitudinal cross-section schematic diagram that Fig. 2 is scanning means shown in Fig. 1.
In a kind of detailed description of the invention, scanning means of the present invention comprises rotating ring 1 and is arranged at least two excellent sources 2 of rotating ring 1 internal perisporium, and each excellent source 2 distributes along the circumference of rotating ring 1, and each excellent source 1 axis all along rotating ring 1 is extended.
Scanning means of the present invention mentioned above can be further improved.Such as, each excellent source 2 can distribute equably in the circumference of rotating cup 1.When being uniformly distributed, the energy in each excellent source 2 can be utilized more fully, when the quantity in excellent source 2 is certain, is uniformly distributed the maximization that can realize sweep limits and arranges, improve scan efficiency.
The internal perisporium of rotating ring 1 axially can arrange special installation position, excellent source, each excellent source 2 is fixed on its inwall along it; Jack can be arranged in rod installation position, source, and excellent source 2 can be inserted and secured in jack, and the locate mode of other routines can certainly be adopted excellent source 2 to be positioned installation position place, excellent source, such as clip etc.Rod source 2 can be elongated club shaped structure, and the end in excellent source 2 can adopt bending to arrange, and forms a buckle, to fasten with the end of rotating ring 1, guarantees to install and stablizes, as shown in fig. 1.
In the preferred embodiment shown in Fig. 2, driving-belt 11 can be adopted to realize the gyration of rotating ring 1, driving-belt 11 can be arranged on the outer peripheral face of rotating ring 1 end, and driving-belt 11 is connected with electric rotating machine 12, so that driven rotary ring 1 constantly rotates under the driving of electric rotating machine 12; When rotating ring 1 rotates, the excellent source 2 be arranged in rotating ring 1 is also rotated thereupon, and excellent source 2 can send ray in the process of motion, and then scans the detecting module of rotating ring 1 circumference distribution, arranges so that detector realizes gain.
Meanwhile, the periphery of driving-belt 11 can also arrange and support guide wheel 13, supports the tangent setting of outer peripheral face of guide wheel 13 and driving-belt 11, and can be pressed together on the endless belt of driving-belt 11; Support guide wheel 13 to be uniformly distributed in the circumference of rotating ring 1 and driving-belt 11, to support fixing equably in the circumference of driving-belt 11, thus improve driving-belt 11 and the reliability be connected between rotating ring 1.
The number supporting guide wheel 13 correspondingly can be arranged according to the size of driving-belt 11 and rotating ring 1 and the degree of reliability connected between the two: when driving-belt 11 is longer or be connected comparatively lax between driving-belt 11 with rotating ring 1, and increase that can be suitable supports the number of guide wheel 13; Certainly, when driving-belt 11 is arranged on the end of rotating ring 1 with larger pretightning force tensioning, when the connection in other words between driving-belt 11 and rotating ring 1 is comparatively reliable, the number of minimizing support guide wheel 13 that can be suitable.
When being provided with multiple excellent source 2 in rotating ring 1, the activity in single excellent source 2 can appropriateness reduce, because multiple excellent source 2 can be scanned the detecting module in its radiation scope respectively, therefore the reduction of single excellent source 2 activity can not affect the correction of detector, but the shortening of sweep time can reduce the radiation injury to human body to a certain extent.
What is more important, scanning means of the present invention adopts the vibrational power flow in how excellent source, reduce the correction time of detector largely, thus improve correction efficiency, and reduce the radiation that operating personnel and patient be subject in instrument calibration process, while ensureing image effect, improve the security of use.Obviously, when adopting multiple excellent source 2 of less activity, scanning means of the present invention to fall radiation effect more obvious.
In the preferred embodiment shown in Fig. 1 and Fig. 2, excellent source 2 can be set to 3, and the activity in single excellent source 2 can be 1 millicurie, has significantly reduce relative to 5 millicuries in excellent source single in prior art; 3 excellent sources 2 can cover the scope of whole rotating ring 1 completely, complete the scanning of detector, and less to the radiation of human body.
Please refer to Fig. 3-Fig. 6, the plan structure schematic diagram that Fig. 3 is scanning means shown in Fig. 1; Fig. 4 is the partial cutaway schematic of a kind of set-up mode in chamber, excellent source provided by the present invention; Fig. 5 is the structural representation of impeller provided by the present invention and a kind of set-up mode of transmission component; Fig. 6 is the close-up schematic view of a kind of set-up mode of impeller provided by the present invention.
One more preferred embodiment in, the side of rotating ring 1 is also provided with room, excellent source 3, rod room, source 3 is arranged on the port of rotating ring 1, rod room, source 3 is provided with the cavity 31 for support stick source 2, cavity 31 can be arranged correspondingly with excellent source 2, also a cavity 31 only can be set, when needs send rod, excellent source 2 be arranged in cavity 31 one by one; Cavity 31 can be arranged, so that by the coated carrying in whole excellent source 2 in the cavity type that can hold excellent source 2; Rod room, source 3 is also provided with impeller 4, and excellent source 2 can push in the jack of rotating ring 1 from cavity 31 by impeller 4, completes and send rod motion, and excellent source 2 directly can realize location by the jack on rotating cup 1.Excellent source 2 can directly be pushed in rotating ring 1 by impeller 4, and does not need to arrange other and auxiliaryly send pole member, and not only simplify the program sending rod, also make scanning means structure of the present invention more simplify, it is convenient more flexibly to use.
For realizing above-mentionedly sending excellent action, impeller 4 can be a push rod, and the end of this push rod is mated with the end in excellent source 2 and arranged; When needing to send rod, apply External Force Acting on push rod, outwards promote excellent source 2 by push rod, thus excellent source 2 is stretched out in cavity 31, then enter in the installation position, excellent source of rotating ring 1.Obviously, the structure of impeller 4 is not limited in push rod.
