A comparison of calibration data from full field digital mammography units for breast density measurements
BACKGROUND Breast density is a significant breast cancer risk factor measured from mammograms. The most appropriate method for measuring breast density for risk applications is still under investigation. Calibration standardizes mammograms to account for acquisition technique differences prior to making breast density measurements. We evaluated whether a calibration methodology developed for an...
متن کاملFarming Techniques, Environmental Challenges, and Technical Efficiency of Sweet Potato Production in Abia State, Nigeria
Viable sweet potato production is hard to achieve with indiscriminate use of farm inputs, resulting to wastage and environmental damages, as consequences are common problems of arable crop farming in Abia State. Issues arising from farm input use and their corresponding implications for environment called for a study on suitable farming practices and farm-specific technical efficiency for optim...
متن کاملCalibration Techniques for Accurate Measurements by Underwater Camera Systems
Calibration of a camera system is essential to ensure that image measurements result in accurate estimates of locations and dimensions within the object space. In the underwater environment, the calibration must implicitly or explicitly model and compensate for the refractive effects of waterproof housings and the water medium. This paper reviews the different approaches to the calibration of u...
متن کاملAn approach for generalizing focus+context techniques
Many efforts have been dedicated to solve the problem of handling large scale workspaces. Numerous techniques has been designed, most of them have lots of specific implementations. Also, there exist some generic implementations that support the development of interfaces using these techniques. The focus+context family lacks of this kind of generic solutions. In this paper we describe a focus+co...
متن کاملMeasurements of breast density: no ratio for a ratio.
Breast density, as visible on mammograms, is generally assessed as the occupied percentage of the breast and is a risk factor for breast cancer. Various studies have looked into the causation and alteration of relative density but the relation of a determinant with a relative measure does not allow a direct etiologic interpretation. It was our goal to compare the effects of known determinants o...
