Description

The delay time service time sweep type digital galactophore machine of integrating detector

Technical field

This utility model relates to a kind of armarium, is a kind of digital galactophore machine that human body mammary gland is detected concretely.

Background technology

The mammary gland machine mainly adopts film imaging and dull and stereotyped digital camera style to the human body mammography at present, the fixed and below platform for video camera photographic imagery of its bulb during the work of mammary gland machine.

Adopt the film imaging mode to operate comparatively loaded down with trivial details and can not be to the image object software processes, thereby make image reach an ideal resolution, the reading method of film can not offer the remote consultation of doctors and provide the remote image diagnosis report in addition.

Adopt dull and stereotyped digital camera style can't maximally utilise bulb X and close bundle position imaging the most uniformly, easy like this dosage and the scope that causes image fault and can't control the X-ray bundle to greatest extent is bigger to person under inspection's radiation.

In addition, traditional imaging mode and dull and stereotyped digital camera mode have stronger scattered light, have a strong impact on the image quality of mammary gland machine.In order to reduce the harmful effect of scattered light, traditional imaging and dull and stereotyped digital camera system generally will add grid.Grid is not only expensive, has increased cost, and can absorb more X-ray, makes the X-ray that can be used to form images become still less, and therefore, system must use bigger X-ray dosage, just can reach the effect that can diagnose.So,, increased patient's X-ray radiation dose though the use of grid has reduced the harmful effect of scattered light.

The utility model content

The purpose of this utility model provides the sweep type digital galactophore machine of the integrating detector of delaying time a kind of service time, solves technical problem how to utilize position imaging the most uniformly of bulb X-ray bundle and low dosage to greatest extent.

The delay time service time sweep type digital galactophore machine of integrating detector comprises rotatable X ray tube, detector, C arm; X ray tube, detector are located at C arm two ends respectively.

The sweep type digital galactophore machine of integrating detector of delaying time said service time also has linkage, and the X ray tube links to each other with the time delays integrating detector through linkage.

Said detector is the time delays integrating detector.

Said X ray tube lower end is provided with the slit light concentrator.

Said slit light concentrator has the strip opening.

Between said X ray tube and the C arm rotating shaft is arranged, this rotating shaft keeps rolling with the X ray tube and is connected.

Said linkage comprises line slideway and connecting rod; The time delays integrating detector is located on the line slideway and keeps being slidingly connected with it; The time delays integrating detector other end then is connected with connecting rod, and this connecting rod other end is then through being connected with the rotating shaft of washing in a pan trip X ray tube.

Said linkage comprises position coder, bulb tumbler, position coder connect hours time-delay integrating detector, and the bulb tumbler then is connected with bulb.

The beneficial effect of this utility model is:

1, ultrahigh resolution: the sweep type digital galactophore machine detector of the integrating detector of delaying time service time can reach every millimeter ultrahigh resolution that the 8-15 line is right, and the resolution of the digital face battle array flat panel detector that uses than the digital galactophore machine on the present domestic and international market exceeds a lot.This high-resolution can let the doctor see littler focus, and is significant to the early diagnosis of breast carcinoma.

2, ultralow radiological dose: the sweep type digital galactophore machine detector of the integrating detector of delaying time service time can reach under the situation of same picture quality, the low 25%-50% of the digital face battle array flat panel detector that uses than the digital galactophore machine on the present domestic and international market.Ultralow radiological dose is very important to the generaI investigation of breast carcinoma, lets the women under same dosage, does more frequent breast carcinoma inspection; Or under the prerequisite of same breast carcinoma proof cycle, receive the harmful effect of littler radiological dose.This also is significant to the early diagnosis of popularizing breast carcinoma.

3, lower cost: the area of the detector of the sweep type digital galactophore machine of the integrating detector of delaying time service time is significantly smaller than the digital face battle array flat panel detector that uses than the digital galactophore machine on the present domestic and international market, and its area has only 1/5th to 1/10th of digital face battle array flat panel detector.Because its area is little, the detector production cost is relatively low.This will play positive impetus to popularizing fast of digital galactophore machine.

The specific embodiment

Please refer to Fig. 1 and Fig. 2, the product of present embodiment mainly includes passive C arm 1, X ray tube 2, rotating shaft 3, connecting rod 4, line slideway 5, slit light concentrator 6, time delays integrating detector 7.Rotating shaft 3 is enclosed within C arm 1 upper end, is with X ray tube 2 in it, this X ray tube 2 can roll in rotating shaft 3.Slit light concentrator 6 be located at X ray tube 2 under.Time delays integrating detector 7 is fixed on C arm 1 lower end; It is placed on the line slideway 5 and can slides above that; Time delays integrating detector 7 has an end to be connected with connecting rod 4, and these connecting rod 4 other ends are connected with rotating shaft 3, when time-delay integrating detector 7 moves on line slideway 5, then drives connecting rod 4 rotations like this; And then 3 rotations of driven rotary axle, guarantee that like this X line of X ray tube 2 emissions can synchronously shine on the time delays integrating detector 7 through seized mammary gland tissue.Because we only need to use the very little part of the X-ray of bulb emission, we can only use the X ray tube the most uniformly the X-ray bundle come scanning imagery, thereby improve picture quality, the uniformitys etc. help the doctor to diagnose more accurately; This technology can use the low-angle bulb to realize large-area exposure image simultaneously, practices thrift cost, improves the probability that product is popularized.Slit light concentrator 6 can be regulated slit according to the size of the pick off of scanning imagery, and unnecessary X line utilizes the shade line material that unwanted ray is shielded.The scanning that can be synchronized with the movement of time delays integrating detector 7 and X ray tube 2 can make image resolution ratio higher, and the while has been reduced the dosage of X ray to greatest extent.

The foregoing description adopts X ray tube 2 to rotate, and can select X ray tube 2 fixing in another embodiment, and the X-ray of being launched can cover the sweep limits of whole imaging.But a band slit light concentrator 6 is arranged between X ray tube 2 and the time delays integrating detector 7.Slit in this slit light concentrator 6 can carry out synchronous scanning and adopt figure with 7 interlocks of time delays integrating detector.

In second embodiment, can select X-ray bulb 2 fixing, the X-ray of being launched can cover the sweep limits of whole imaging.Time delays integrating detector 7 need not and 2 interlocks of X-ray bulb, can directly scan and adopt figure.
