Premarket evidence — what FDA accepted
source quote (p.3)
“This computed tomography system is intended to generate and process cross-sectional images of patients by computer reconstruction of x-ray transmission data.”
source quote (p.6)
“The platform software for the NAEOTOM Alpha is syngo CT VB10 (SOMARIS/10 syngo CT VB10). It is a command-based program used for patient management, data management, X-ray scan control, image reconstruction, and image archive/evaluation.”
source quote (p.20)
“myExam Compass collects information about the current patient to dynamically adapt the scan parameters or exchange recon jobs according to the patient's characteristics”
source quote (p.31)
“Siemens conforms to the Cybersecurity requirements by implementing a process of preventing unauthorized access, modifications, misuse or denial of use, or the unauthorized use of information that is stored, accessed, or transferred from a medical device to an external recipient.”

Bench
sample size not stated
endpoints: accuracy of FAST Isocentering, FAST Range, and FAST Direction; reduction of artefacts attributed to stack misalignment; introduction of new artefacts by SAC reconstruction; image quality in quantitative standard physics phantom-based measurements (noise, homogeneity, high-contrast resolution, slice thickness and CNR); image quality in quantitative and qualitative phantom-based measurements with respect to metal objects; accuracy of the automatic needle detection algorithm; reduction of necessary user interactions for navigating to a needle-oriented view; T3D reconstructions in Quantumpeak mode are possible with the sharpest available kernels; Quantumpeak scan mode allows reconstructions of monoenergetic images at energy levels from 40 to 190 keV; image noise and visual assessment of image quality in ECG gated acquisitions; HU accuracy in the extended field of view region; phantom diameter accuracy
