The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, this utility model is described in further detail.In the accompanying drawings, identical parts or the parts with identical function adopt identical sign flag, and the repetitive description thereof will be omitted.
Fig. 1 means the schematic diagram with the related typical X-ray shooting system 1 of this utility model.As shown in Figure 1, as the X-ray shooting system 1 of for example medical application, mainly comprise X-ray platform (being equipped with X-ray detector), X ray generating unit, control part, display part, operating portion, radioscopic image handling part, exterior storage portion etc.
In Fig. 1, exemplified with horizontal X-ray platform 10.As shown in Figure 1, when the examinee in the state of couching carries out radioscopic image detection, examinee for example couches in X ray generating unit and is equipped with between the X-ray platform 10 of X-ray detector.Control part in X-ray shooting system 1 carries out position adjustment to the X-ray detector in X-ray platform, is located at suitable position (for example making X-ray detector be positioned near the position of human lung to obtain lung X-ray ray image).
Then, control part is controlled X ray generating unit (x-ray source) and is produced X ray, and this X ray forms and comprises for example X ray image of pulmonary of inside of human body through human body.Then, this X ray image is transformed into visible images by the X-ray detector of X-ray platform 10, and by for example photodiode, visible images is converted to the signal of telecommunication.Then, the processing of the X photographs handling part that process is follow-up etc., in display part, display case is stored in exterior storage portion as the digital picture of resulting pulmonary or by this digital picture.
Fig. 2 means the side view of the X-ray platform 10 that this utility model is related.Fig. 3 means X-ray detector 15 that the related X-ray platform 10 of this utility model assembles and the axonometric chart of X-ray detector basket 14.As shown in Figure 2, the related X-ray platform 10 of present embodiment is to possess a plurality of foots 11 and the X-ray platform of the mounting examinee's that supported by a plurality of foots 11 top board 12.In addition, between foot and top board 12, be also provided with the bracing frame 13 for roof supporting 12.In this case, more firmly roof supporting 12, and top board 12 can all around freely move with respect to bracing frame 13, the detection position with respect to examinee can be adjusted to desirable position thus.Have, the bottom of this bracing frame 13 is also provided with for holding the X-ray detector basket 14 of X-ray detector again.Particularly, X-ray detector basket 14 can be extracted out and push from bracing frame 13 in the mode of pull.For example, the back side of the bracing frame 13 of X-ray platform 10 is provided with guide rail or the chute matching with X-ray detector basket 14.Like this, from X-ray detector basket 14, can easily take out or put into X-ray detector 15.
In addition, the plane (being XY plane) that this X-ray detector basket 14 can be configured to along bracing frame 13 is mobile, thus, can be by the position of X-ray detector is set easily along XY planar movement X-ray detector basket 14 on bracing frame 13, thus each position of subject can be detected easily.
Fig. 4 means the top view of the X-ray platform 10 that this utility model is related.Fig. 5 means the circuit diagram of the X-ray detector position detection part 20 of the X-ray platform 10 that this utility model is related.As shown in Figure 4, Figure 5, at the long side direction of X-ray platform 10, dispose 2 terminals 21, preferably these 2 terminals 21 are magnetic terminal, but are not limited to this.Also can be other terminals that can conduct electricity.A part for X-ray detector basket 14 (contact site) 141 can be conducted electricity, and is preferably by metal and forms.X-ray detector position detection part 20 also possesses conduction detection portion 22, it detects between 2 terminals 21 whether conducting, thereby when operator pushes X-ray detector basket 14 when 2 terminals 16 are contacted with the contact site of X-ray detector basket 14, conduction detection portion 22 detects between 2 terminals 21 conducting occurs.Then, detection unit 23, based on this testing result, judges whether X-ray detector 15 is disposed at normal operation position with respect to X-ray platform 10.Normal operation position refers to, after X-ray detector 15 is loaded into X-ray detector basket 14, the contact site of X-ray detector basket 14 fully contacts with 2 terminals 21, thus position when X-ray detector 15 is fixedly secured.Herein, in a preferred embodiment, terminal 21 consists of Magnet, a part for X-ray detector basket 14 (contact site) 141 consists of metals such as ferrum, thus, operator is when being pushed into the position approaching with terminal 21 by X-ray detector basket 14, and X-ray detector basket 14 is because magnetic action is drawn to terminal 21 places, thereby between two terminals 21, conducting occurs.Like this, operator does not need X-ray detector basket 14 to push hard to the position contacting with terminal 21, just can easily make, between 2 terminals 21, conducting occurs, thereby be more preferably.In addition, between 2 terminals 21, be connected with power supply 25 and resistance 26, when there is conducting by X-ray detector basket 14 between 2 terminals 21, have electric current and flow through this resistance 26.The voltage at these resistance 26 two ends for example detects in conduction detection portion 22, and exports testing result to detection unit 23.Detection unit 23 is such as being the electronic components such as switching tube, and controls notification unit 24 and notify.For example, detection unit output high level makes notification unit 24 effective, and notification unit can make the electronic component that operator's vision or audition can perception for LED, speaker etc.
Below, with reference to figure 2~Fig. 5, illustrate in greater detail the process whether X-ray detector is positioned at normal operation position that detects.
First, operator is installed on X-ray detector 15 in X-ray detector basket 14, then X-ray detector basket 14 is pushed along the guide rail on X-ray platform 10 or chute.Afterwards, in the X-ray platform of prior art, owing to there not being X-ray detector position detecting mechanism, therefore need operator firmly to shift X-ray detector basket 14 onto the end, in order to confirm that whether X-ray detector 15 is in assigned position, operator even need bending to confirm by visual.Yet with respect to this, in embodiment of the present utility model, operator are pushed into X-ray detector basket 14 position that approaches terminal 21, by the magnetic action of terminal 21, X-ray detector basket 14 is drawn to normal operation position.Then,, because terminal 21 is by a part (contact portion) conducting of X-ray detector basket 14, conduction detection portion 22 detects to be had electric current to flow through in resistance 26 and exports testing result to detection unit 23.Finally, detection unit 23 is controlled notification unit 24 based on this testing result, thereby notifies operator's X-ray detector 15 to be positioned at normal operation position.Thus, operator can learn that X-ray detector 15 is in assigned position easily, thereby improve the operating efficiency of X-ray platform 10.
Although below in conjunction with the accompanying drawings and embodiments this utility model is illustrated, is appreciated that above-mentioned explanation does not limit this utility model in any form.Those skilled in the art can be out of shape and change this utility model as required in the situation that not departing from connotation of the present utility model and scope, and these distortion and variation all fall in scope of the present utility model.
