We investigated how varying the x‐ray tube voltage and image receptor input exposure
affected image quality and patient radiation doses in interventional neuroradiologic imaging …

Digital subtraction angiography (DSA) has been widely accepted and applied. The
concentration of iodine in the vessels of interest is low in intravenous DSA. The resultant …

Digital subtraction angiography (DSA) is based on digital image processing with logarithmic
subtraction and edge enhancement. It is used increasingly for the visualization of blood …

The operating characteristics of a digital subtraction angiography unit were evaluated.
Measurements included image intensifier and system linearity, uniformity, quantum and …

Purpose: X‐ray digital subtraction angiography (DSA) is widely used for vascular imaging.
However, the need to subtract a mask image can result in motion artifacts and compromised …

抄録 Quantitative digital subtraction angiography (DSA) image analysis based on
densitometry is widely accepted and used. For the densitometoric DSA image analysis, it is …

Purpose: We investigated the relationship between the amount of radiation exposure to the
operator during tableside manual-injection angiographic procedures including digital …

Purpose To test the hypothesis that an image noise reduction algorithm designed for digital
subtraction angiography (DSA) in interventional neuroradiology enables a reduction in the …

Digital subtraction angiography (DSA), utilizing computerized x-ray imaging equipment for
image acquisition and subtraction, will provide substantial improvements in blood vessel …

A figure of merit (FOM) has been developed which embodies parameters related to image
quality in the numerator and radiation integral dose to the patient in the denominator. In this …
