BACKGROUND Women's health is defined as a continuum throughout their whole lives. In China, women receive life-round preventative and curative health care from the health system, although the universal access to reproductive health has already been basically achieved in China, the situation of women's access to curative health care is still unknown. METHODS Data from the national maternal and...
Background Cancer survivors rate fertility as one of the most important determinants of their quality of life in the years after cancer treatment. We seek to describe the reproductive goals of women affected by gynecologic cancers and investigate their specific challenges during fertility preservation (FP) counseling. Methods Univariate & multivariate logistic regression were used for quantit...
BACKGROUND Equity in distribution of resources is considered as an important priority in health care systems. Equitable distribution of obstetrics and gynecology (Ob/Gyn) services in the country level is critical in maternal and neonatal health for qualitative promotion of maternal care in pregnancy, delivery, and post-delivery periods. OBJECTIVE The present study aimed at determining regiona...
Introduction:The commercial 252Cf sources are too large in size and clinical applications of neutronbrachytherapy (NBT) are limited to a small number of intracavitary treatments of cervical cancers. Recently, under the Cooperative Research and Development Agreement (CRADA) with Isotron Inc., the Oak Ridge National Laboratory (ORNL) encapsulated a new medical 252Cf sources, cal...
Background: Quality assurance and peer-review practices in surgical pathology have been well described in the literature, but the majority of these reports apply to the realm of general surgical pathology. We focused on the peer-review reporting system of a specialty women’s health pathology practice consisting exclusively of breast and gynecologic pathology, with the specific aims of identifyi...
Ultrasound-Fluoroscopy fusion is a key step toward intraoperative dosimetry for prostate brachytherapy. We propose a method for intensity-based registration of fluoroscopy to ultrasound that obviates the need for seed segmentation required for seed-based registration. We employ image thresholding and morphological and Gaussian filtering to enhance the image intensity distribution of ultrasound ...
This paper details a practical method for deriving the reference air kerma rate calibration coefficient for Farmer NE2571 chambers using the U.K. Institute of Physics and Engineering in Medicine (IPEM) code of practice for the determination of the reference air kerma rate for HDR (192)Ir brachytherapy sources based on the National Physical Laboratory (NPL) air kerma standard. The reference air ...
A new phantom was designed and built in order to quantify the spatial distortions produced in images taken by MRI for treatment planning of brachytherapy for cervical cancer. It was found that for a field of view of 30 cm; large enough to incorporate the anatomy required to plan treatment, the distortions were of the order of millimetres or individual pixels. The images were compared to ones ta...
