title: Misalignment of multiple photopeak analyzer outputs: effects on imaging. Concise communication.
abstract: 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.
