Automated patient-derived noise power spectrum estimation in abdominal CT: a preliminary validation
Background. Established methods are available for measuring the noise power spectrum (NPS) in computed tomography (CT) by using uniform phantoms. However, in clinical practice, direct estimation of this metric from patient images is desirable for continuous image quality monitoring and protocol optimization. Methodolog...
