Abstract

We evaluated an experimental digital subtraction unit in terms of field uniformity, linearity of signal response to x-radiation, response of the log amplifier, and imaging capability as measured with the Rose phantom. For comparison, conventional film subtraction phantom measurements were made. Our results indicate that this unit exhibits greater sensitivity to contrast media than conventional film subtraction units.

摘要

我们根据视野均匀性、对X射线信号响应的线性、对数放大器的响应以及用罗斯体模测量的成像能力，对一个实验性数字减法单元进行了评估。作为比较，还进行了传统胶片减法体模测量。我们的结果表明，该单元对造影剂的敏感性比传统胶片减法单元更高。
