STRATON X-ray tube

Our unparalleled 0 MHU STRATON X-ray tube has caused a paradigm shift in CT imaging. The tube’s direct anode cooling eliminates the need for heat storage, permitting a compact design and the fastest CT gantry rotation for all applications. In cardiac imaging, where the ability to freeze motion is critical, Biograph™ 40 and 64 provide you with super-fast rotation time, making noninvasive cardiac diagnosis routinely available.

To increase temporal resolution, the proprietary STRATON X-ray tube enables a fast gantry rotation time of 0.33 s, resulting in motionand artifact-free imaging of the heart.

z-Sharp technology

Instead of decreasing the size of detector elements to improve spatial resolution, z-Sharp technology on the Biograph 40 and 64 utilizes two overlapping X-ray beams, resulting in significantly increased resolution without a corresponding increase in dose. This provides you with the industry-leading isotropic resolution of 0.33 mm at any scan and rotation speed, and at any position within the scan field. In addition, with our proprietary z-UHR technology, the system adapts for ultra-high resolution bone imaging for wrist, joint, or inner ear studies. We push the boundaries of spatial resolution even further providing unparalleled 0.24 mm isotropic resolution — until now seen only with research flat panel and Micro CT technology.

Conventional PET or HD•PET:

What’s the real difference?

When a photon strikes a crystal, it travels a certain distance before its energy is converted into light. If the photon comes from the center of the field of view (FOV),the line of response (LOR) is likely to be correctly localized in the crystal in which the photon entered. The further away from the center of the FOV, the less likely the LOR will be calculated correctly because the photon will hit the crystal on an angle and continue traveling to another crystal before it lights up. A Point Spread Function (PSF) describes the response of an imaging system to a point source or point object. A system that knows the response of a point source from everywhere in its FOV can use this information to recover the original shape and form of imaged objects. PSFs are used in precision imaging instruments, such as microscopy, ophthalmology, and astronomy (e.g. the Hubble telescope) to make geometric corrections to the final image.

Conventional PET uses the same reconstruction principles across the entire FOV and does not take into account the detector geometry and mispositioning of the LORs. This results in fuzzy edges and increased distortion further

from the center of the FOV.

LSO: state-of-the-art crystal technology

With more than 10 years of experience in Lutetium Oxyorthosilicate (LSO) scintillator crystal technology, Siemens is a pioneer in innovative PET imaging techniques. The Biograph TruePoint PET·CT employs patented LSO PET detectors that provide clear and fast images. A PET scanner’s performance greatly depends on the scintillation properties of the detector crystal material. With a fast scintillation decay time of 40 ns and the highest density available, LSO crystals offer the best combination of properties of any PET scintillator known today. LSO offers a fast coincidence timing window of 4.5 ns for efficient rejection of random events and enough light output for high energy resolution discrimination to facilitate the efficient rejection of randoms — all to provide high count rate statistics, which are essential to high speed PET scanning.
