As shown in Figure 1, head 100, bed portion 200 can be comprised according to the bone density measurement system of the automatic recognizing site of the utilization of an embodiment of the invention and be connected to the central control 300 in described head 100 and described bed portion 200 by wireless or wired mode.Wherein, head 100 comprises: x-ray source portion 110; Location recognition photographic head 10 is utilized to come the location recognition portion 120 of identification marking 20; And X-ray control unit 130.Bed portion 200 comprises X-ray detector portion 210.
Concrete understanding is carried out for each structure as follows.
In bone density measurement system, when generally using thin pen beam (pencil-beam) form or use fan beam (fan-beam) form X-ray irradiation, photography time, namely the movable time is minimized needed for the measured, the shortest be 1 point 30 seconds to the longest be 30 minutes, and when as when being applicable to the bone density measurement system of whole body type instead of the specific part such as foot neck or wrist, there is following problem.That is, make gauger and the measured frequently produce unnecessary contact to judge the body part position information of the measured, and unnecessary X-ray can be irradiated owing to irradiating unified X-ray.Thus, the X-ray (X-ray) of conical beam (cone-beam) form can be produced according to the x-ray source portion 110 of the described head 100 of the bone density measurement system of the automatic recognizing site of the utilization of an embodiment of the invention.
By as mentioned above, owing to photographing with face unit, the shot time is about 1 second, thus has the advantage minimizing unnecessary x-ray bombardment.
The location recognition portion 120 of described head 100 utilizes described location recognition photographic head 10 to identify to be fixed in advance the multiple described labelling 20 of the measured, thus can judge the body position information of the measured.
Multiple described labelling 20 is identified by the described location recognition portion 120 according to an embodiment of the invention, thus can the body position information of the measured of accuracy of judgement.
At this, body position information refers to the information to the body part measured needed for the measured, according to the bone density measurement system of the automatic recognizing site of the utilization of an embodiment of the invention and measuring method thereof by identifying the multiple described labelling 20 being fixed on the measured, after judging the information of the body part measured needed for the measured, described bed portion 200 is moved up and down in the plane, thus the specific part that described x-ray source portion 110 easily will be measured needed for x-ray bombardment to the measured can be made.
More specifically, as shown in Figure 3, fixing or mark described labelling 20 on the desired areas such as the head of the measured, neck cervical region, chest, abdominal part and huckle, thus described location recognition photographic head 10 can be made easily to recognize described labelling 20.
Now, the one side of described labelling 20 can be formed as adhesive member and be fixed on the body part of the measured, or the one side of described labelling 20 can be formed as producing the friction member of frictional force and be fixed on the body part of the measured.At this, for described labelling 20 being fixed on method only an embodiment of the invention of the body part of the measured.
Further, when having a basic biological information of essential information, the i.e. height etc. of the measured by the input of described central control 300, described location recognition portion 120 can more promptly recognize be fixed on the measured head to the described labelling 20 on huckle, thus the described body position information of the measured can be judged.
Now, by described location recognition photographic head 10 only to recognize described labelling 20, and do not affect the X-ray produced from x-ray source portion 110.
The X-ray control unit 130 of described head 100 can comprise distance measurement sensor 30.
As shown in Figure 4, described X-ray control unit 130 utilizes described distance measurement sensor 30 to judge to be fixed on the distance between the multiple described labelling 20 of the measured and described distance measurement sensor 30 in advance, thus can control the x-ray bombardment amount from the irradiation of described x-ray source portion 110.
More specifically, according to the described head 100 of the bone density measurement system of the automatic recognizing site of the utilization of an embodiment of the invention due to height cannot be regulated, therefore when the measured lies in a portion 200, also utilized the size of the described labelling 20 recognized by described distance measurement sensor 30, thus judge described head 100 and described labelling 20, distance namely between the measured.
By body thickness, the i.e. coefficient of condition of the measured can be measured as mentioned above, and control the x-ray bombardment amount from the irradiation of described x-ray source portion 110 thus.
In other words, because the low-down people of coefficient of condition is different to the fat deposit be distributed between bone from meat with the very high people of coefficient of condition, therefore, when the X-ray that irradiation irradiation dose is identical, bone image can produce error, and prevent this problem occurs by described X-ray control unit 130.
Now, in bone density measurement system according to the automatic recognizing site of the utilization of an embodiment of the invention, even without arranging described X-ray control unit 130, i.e. described distance measurement sensor 30, also can identify described labelling 20 by described location recognition photographic head 10, and be of a size of with described labelling 20 distance that benchmark judges between described labelling 20 and described head 10.That is, when when the size of described labelling 20 is large, can be judged as that the distance between the measured and described head 100 is close.
Thus, as mentioned above, with the coefficient of condition of the distance judged as benchmark the measured, and coefficient of condition computing information can be passed to described central control 300, described X-ray control unit 130 can control the x-ray bombardment amount of irradiating from described x-ray source portion 110.
The X-ray detector portion 210 in described bed portion 200 is designed to relative with described x-ray source portion 110, and can detect and be irradiated by described x-ray source portion 110 and the X-ray at feature position through the measured, thus the bone image of two dimensional surface form can be generated.
More specifically, described X-ray detector portion 210 detects the X-ray of the specific part through the measured, and its testing result can be generated as analogue signal by X-ray detector portion 210, and described analogue signal is converted to digital signal and generates bone image.
Described X-ray detector portion 210 is by generated described bone image transfer to described central control 300, and described central control 300 can judge the bone density of the measured by described bone image.
In addition, described X-ray detector portion 210 can also comprise scintillator (scintillator) layer and the photographic head for described scintillator layers of photographing.
Described scintillator layers can radiate visible rays after receiving X-ray, by the photographic head for described scintillator layers of photographing, namely by visible rays photographic head, and the picture of described scintillator layers of photographing
, thus the bone image as X-ray image can be obtained.
Now, the described bed portion 200 with described X-ray detector portion 210 can be moved along above-below direction by the action of other lifters (not shown), so that the measured can be made easily to lie in described bed portion 200, it can according to the manager of described central control 300, the i.e. height in regulation bed portion 200 according to the control of gauger.
