Abstract
The present invention relates to a computerized tomography device for mammary gland, which uses a special mammary gland positioning device and a combined type X-ray generator. A scanning disk rotates around a mammary gland longitudinal axis, and the scanning operation in each bedding surface is completed by moving a scanning frame so that the CT scanning operation for the mammary gland transverse axis is completed. Thus, the present invention provides a new image examination method for diagnosing the mammary gland disease. Moreover, a scanning device directly carries out the puncture biopsy in the CT guidance so as to confirm the diagnosis and guide the treatment.
Description
The present invention relates to a kind of computer tomoscanning device, it is a kind ofly with the X line mammary gland to be carried out tomoscan, carries out data acquisition and processing (DAP) by computer, finally obtains the image documentation equipment of mammary gland layer images.
The device that has existed some can realize mammary gland is carried out computed tomography in the prior art, promptly common X line CT scan device (hereinafter to be referred as CT), but these devices can only carry out the transverse axis bit scan and can not carry out the transverse axis bit scan to mammary gland human body.In addition, these CT scan devices must could obtain the CT scan image of mammary gland when human chest is scanned, and this has increased the X line dosage of absorption of human body undoubtedly.
The objective of the invention is to overcome the shortcoming of prior art, a kind of computer tomoscanning device that is exclusively used in mammary gland is provided.
Technical solution of the present invention is, a kind of computer tomoscanning device that is used for mammary gland, comprise disk scanner 1 and gantry 2, glandula mammaria positioning device and combination type X line generator 8, described glandula mammaria positioning device comprises the special-purpose mammary gland cover 10 that is used for fixing breast, the mammary gland cover is fixed on fixed mount 14 on the scanning means shell, there is a negative pressure ventilation mouth 11 on the top of described special-purpose mammary gland cover 10, there is inducing QI top board 9 inboard of described negative pressure ventilation mouth 11, described negative pressure ventilation mouth 11 and inducing QI top board 9 cooperatively interact, and breast is fixed in the mammary gland cover 10, during scanning, disk scanner 1 is around the rotation of the mammary gland longitudinal axis, and gantry 2 controlled level move.
Again:
The end mouth of above-mentioned special-purpose mammary gland cover (10) is installed rubber seal 15, and described special-purpose mammary gland cover 10 inwalls have an emulsion layer 12.
The below of above-mentioned inducing QI top board 9 is equipped with elasticity sponge 13.
The case surface of above-mentioned special-purpose mammary gland cover 10 is provided with position line.
Because the present invention adopted said structure, both be convenient to the centralized positioning of mammary gland, can prevent moving of mammary gland in the scanning process again, guarantee to obtain mammary gland layer images clearly; And can improve the accuracy of aspiration biopsy and reduce the absorption of human body X ray.
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of mammary gland computer tomoscanning device perpendicular to central shaft.
Fig. 2 is the structural representation that the mammary gland computer tomoscanning device is parallel to central shaft.
Fig. 3 is special-purpose mammary gland cover case surface positioned parallel line sketch map.
A kind of computer tomoscanning device that is used for mammary gland, it is made up of disk scanner 1, gantry 2, glandula mammaria positioning device and combination type X line generator 8, glandula mammaria positioning device of the present invention is made up of parts such as a special-purpose mammary gland cover 10 and fixed mounts 14 thereof, the end mouth of special-purpose mammary gland cover 10 is installed rubber seal 15, rubber seal is close to the root of those who are investigated's mammary gland, and the inwall of special-purpose mammary gland cover is equipped with an emulsion layer 12.Bleed by the vertical negative pressure ventilation mouth 11 of mammary gland cover, the internal orifice of negative pressure ventilation mouth 11 has inducing QI top board 9, and there is the elastic sponge 13 that is equipped with according to those who are investigated's mammary gland size the below of inducing QI top board 9.
Comprising a combination fuel tank 6 in the combination type X line generator 8, is X spool 5 at an end that makes up fuel tank.The other end is a high tension generator 7, and the anode 4 of X spool 5 is drawn from the side of X spool 5, and anode target surface 3 adopts Mo, is beneficial to soft-tissue imaging; High tension generator 7 adopts single-ended positive high voltage earthing mode, so that the anode 4 of the X spool 5 of close human body in this scanning means is connected to earth potential, guarantees those who are investigated's safety.
What be worth emphasizing is, the case surface of the special-purpose mammary gland cover of this scanning is provided with position line, it below is one of them example, as one group of positioned parallel line (Mo_Mn), each root position line all is truncated into two sections (Mna_Mnb), from start line (Mo), the length that is positioned at the line segment (Moa_Mna) of homonymy is successively decreased gradually, the length of the line segment of opposite side (Mob_Mnb) then increases progressively gradually, the length difference of adjacent segments is the c millimeter, adjacent segments be spaced apart the d millimeter, wherein length difference c millimeter is corresponding with scanning slice face thickness c millimeter, the d millimeter is used for the body surface location at interval.Therefore this scanning means can directly carry out aspiration biopsy under the CT guiding, certainly diagnosis and guidance treatment.
Before making CT scan, mammary gland is sucked in the special-purpose mammary gland cover, and make mammary gland be full of the mammary gland cover as far as possible, reuse mammary gland cover fixed mount 14 is fixed the position of mammary gland cover with respect to the shell of scanning means.When this device began to scan, disk scanner 1 was around the rotation of the mammary gland longitudinal axis, and gantry 2 moves according to predefined aspect spacing parameter controlled level, finishes the CT scan to each aspect of transverse axis position of mammary gland.
