Breast carcinoma is the malignant tumor that is taken place by the breast duct epithelium, is women's common cancer.According to authoritative medical information statistics, per 13 minutes of the whole world just has a people to die from breast carcinoma, and breast carcinoma has become the important diseases of serious threat women's health.Along with morbidity increases, mortality rate is also in obvious rising.
The radiotherapy of tumor carries out tumor treatment with high-octane ray exactly.Specific to the radiotherapy of breast carcinoma, it is one of breast carcinoma three big treatment meanss, i.e. operative treatment, chemotherapy and radiotherapy, and radiotherapy plays an important role in the middle of the treatment of breast carcinoma.
In " breast carcinoma clinical practice guideline " that the non-profit-making academic alliance (NCCN) that is made up of the top Cancer center in the 21 tame worlds works out, radiotherapy is one of indispensable treatment means of breast cancer treatment, and is extremely important for the local dosage irradiation of mastadenoma bed.But, be applied to clinical radiotherapy apparatus for existing, ray is overlapped with focus all the time, but be a problem demanding prompt solution.This be because, mammary gland is the organ that is attached on the thoracic wall, during roentgenization, the patient lies on the back on therapeutic bed, cause mammary gland along with people's breathing ceaselessly moving, be fixed and be used for irradiated ray, this just makes that ray can't overlap with focus all the time between the light period.In the middle of existing clinical treatment, the solution of employing is the range of exposures that enlarges ray, and focus is under the irradiation of ray in moving process all the time.This way, though solved the problem of missing the target of focus during the roentgenization, its negative effect is to cause the unnecessary excessive damage of focus periphery normal structure.
In traditional way, the patient is before carrying out radiotherapy, for determining the position of focus, must at first determine the three-dimensional coordinate of focus by image documentation equipment, then the patient is positioned on the therapy apparatus, determines the repeated positioning precision of patient on therapy apparatus by drawing at the gauge point and the special-purpose resetting labelling chi of patient's body surface.This method can only be determined the repetitive positioning accuracy of patient's internal lesions indirectly by patient's body surface labelling, and repetitive positioning accuracy is poor, and can't know resetting error accurately.
Summary of the invention
For solving the repetitive positioning accuracy difference that above prior art exists and can't knowing resetting error problem accurately, the invention provides a kind of positioner of mammary gland, make focus before roentgenization, accurately to locate by image documentation equipment, avoid the resetting error, the accurate irradiated lesion of navigation rays, and make focus between the light period, maintain static.This positioner can be guaranteed the high-dose irradiation to the mastadenoma bed, can avoid the unnecessary excessive damage to tumor bed normal surrounding tissue simultaneously.
The technical solution used in the present invention is: a kind of glandula mammaria positioning device is provided, it comprises the cover of fixed in shape and is connected in imaging device on the described cover with dismantled and assembled or movable connection method, the coordinate position of described imaging device is known, and it is used to scan mammary gland, obtains anatomic image and converses corresponding coordinate position.Because the above position that converses is the position that ray will shine, so can thoroughly avoid putting bit error.
Further, positioner of the present invention can also inject an amount of tissue equivalent's liquid in cover, make mammary gland during ultra sonic imaging and roentgenization, be immersed in tissue equivalent's liquid, thereby can be for needed continuous media is provided in the imaging region, and, be convenient to the calculating of exposure dose because the density of this tissue equivalent's liquid is close with human body soft tissue density.
Further again, positioner of the present invention also comprises the base plate of perforate, and described perforate is used to embed described cover, and it is thereon prostrate and its breast overhang in the described cover naturally that described base plate is used for the patient.Adopt the prostrate reason of patient to be, when the patient lies on the back on therapeutic bed,, breathe and make chest dipping and heaving (it is thoracic respiration that the women breathes), and then drive the mammary gland dipping and heaving because the therapeutic bed base plate is close at the back.When the patient taked prostrate attitude, thorax was limited by therapeutic bed, and breathing can only cause the fluctuating at back, can't drive mammary gland and move, and mammary gland passes through the perforate nature dead hang of bed base plate in described cover, makes mammary gland away from thoracic wall, is convenient to roentgenization.
