Premium PET/CT technology with a minimal investment.
Siemens' PET/CT Technology Foundation
The finer points of a high-quality image
The value of PET/CT in patient care is in the details—more precise information leads to greater potential for an earlier diagnosis and a more definitive treatment strategy.
Our PET/CT technology foundation delivers excellent lesion detectability, spatial resolution and quantification accuracy. With this distinct level of quality and reproducibility, you can bring the standard of care to more patients.
Siemens’ unique LSO crystals are grown in-house for consistent quality. Compared to BGO crystals1, they scintillate faster and have a higher light output, providing better image quality and enabling Time-of-Flight.
The smaller the crystals, the sharper the image. Biograph Horizon2’s OptisoHD detectors feature LSO crystals cut into 4 mm elements and arranged with no gaps between detector blocks to provide very high spatial resolution and lesion visualization.
Biograph Horizon’s LSO-based detectors and high-speed electronics support Time-of-Flight2 for improved signal-to-noise ratio. This enables faster scans, lower injected dose and better image quality.
Siemens’ market-leading CT technologies further enhance your imaging capabilities. They also give you the ability to scan a wider variety of patients and more fully utilize your system. For example, SAFIRE2 lowers dose by up to 60%3, and iMAR2 reduces metal artifacts.

3In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. The following test method was used to determine a 54-60% dose reduction when using SAFIRE reconstruction software: Noise, CT numbers, homogeneity,
