Embodiment Construction
[0041] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0042] The invention provides a nonlinear fusion method of internal and external radiotherapy doses for cervical cancer, which is characterized in that it is implemented according to the following steps:
[0043] Step S1: Acquiring CT images of internal radiation therapy, CT images of external radiation therapy, dose distribution of internal radiation therapy and dose distribution of external radiation therapy of cervical cancer to be detected;
[0044] Step S2: Correspondingly mapping the CT images of internal radiation therapy to CT images of external radiation therapy through nonlinear image registration, so that the images of internal and external radiation therapy can achieve consistent anatomical structure, and eliminate the errors caused by patient setup errors, treatment responses and physiological activities, etc. The deviation o...
