With the increased use of gallium-67 citrate and cameras with multiple pulse-height analyzers, the spatially linear response of the camera with respect to simultaneous use of multiple pulse-height analyzers is essential. Nonlinear response will result in spatial distortion and loss of resolution and image contrast. It is not acceptable under these circumstances to pay for increased count density with decreased resolution.
随着枸橼酸镓-67和带有多个脉冲高度分析仪的相机使用的增加，相机对于同时使用多个脉冲高度分析仪的空间线性响应至关重要。非线性响应会导致空间失真以及分辨率和图像对比度的丧失。在这些情况下，以降低分辨率为代价来换取增加的计数密度是不可接受的。
