1. Based on Stanford University study, as published in Song, H., Ferri, V., Duan, H. et al. SPECT at the speed of PET: a feasibility study of CZT-based whole-body SPECT/CT in the post ¹⁷⁷Lu-DOTATATE and ¹⁷⁷Lu-PSMA 617 setting. Results may vary since the scan time depends on the clinical task, patient size, anatomical location and sites’ clinical practice. A radiologist should determine the appropriate scan time for the particular clinical task.

3. Compared to NM/CT 870 DR and NM/CT 870 CZT. StarGuide SPECT reconstruction with scatter used the system’s factory NEMA NU 1-2018 resolution protocol which uses the same method (BSREM with Clarity 3D) as its clinical bone protocol. NM/CT 870 DR and NM/CT 870 CZT SPECT reconstruction used Evolution for Bone (OSEM). NM/CT 870 DR used LEHR/LEHRS collimators and NM/CT 870 CZT used the WEHR collimator.
4. Improved volume sensitivity compared to NM/CT 870 DR using LEHR/LEHRS collimator and NM/CT 870 CZT using WEHR collimator.

Since there is no typical hospital and many variables exist, such as hospital size, case mix, etc., there can be no guarantee that other customers will achieve the same results.
6. Clarify DL improves image quality performance measured by Structures Similarity (SSIM), Mean Squared Error (MSE), and Peak Signal-to-Noise Ratio (PSNR), as compared to StarGuide's non-DL bone SPECT factory reconstruction presets, demonstrated using digital phantom simulations with inserted lesions of known size, location, and contrast, for AC and NC images. Because phantom results may not always match those of clinical imaging, the actual IQ improvement will depend on the clinical task, patient size, and clinical practice (e.g. injected dose, scan time).
7. CNR improved for NC images and remained equivalent for AC images, as compared to StarGuide's non-DL bone SPECT factory reconstruction presets. Demonstrated using digital phantom with inserted lesions of known size, location, and contrast, for AC and NC images. Because phantom results may not always match those of clinical imaging, the actual IQ improvement will depend on the clinical task, patient size, and clinical practice (e.g. injected dose, scan time).
