Contrast phantom tomosynthesis
The fda alternative standard specifies that the new manual may be used only for full-field digital mammography systems without advanced imaging capabilities (eg, tomosynthesis and contrast enhancement). The emphasis will be on digital breast tomosynthesis with secondary discussion of contrast-enhanced digital mammography and combined digital mammographic and ultrasound equipment it should be emphasized, as of this writing, all the aforementioned technologies are investigational in the united states and none are approved for clinical use by . The objective of this research is to demonstrate an in-line phase contrast tomosynthesis prototype operated under high x-ray tube voltage, and a phantom study was conducted to characterize the potentials of this system. In-line phase-contrast breast tomosynthesis: a phantom feasibility study at a synchrotron radiation facility phys med biol, 61 (16) (2016), p 6243.
