Siemens Debuts Smallest Mobile PET/CT System

Siemens Healthineers (Erlangen, Germany) has introduced a mobile configuration of the Biograph Horizon positron emission tomography/computed tomography (PET/CT) system, which delivers high-end functionality at an attractive total cost of ownership.

The mobile-ready version of the Biograph Horizon is intended for cost-conscious healthcare facilities that do not yet possess the patient volume to support installation of a fixed PET/CT, and is also suitable for consolidated health systems looking to tailor their imaging delivery strategy in diverse service areas, with clinical indications in oncology, neurology, and cardiology. With the addition of the mobile version of the Biograph Horizon, the entire line of Biograph PET/CT systems from Siemens Healthineers is now available in both mobile and fixed configurations.


The system’s 4 mm lutetium orthosilicate (LSO) crystals scintillate faster and boast a higher light output than commonly used bismuth germanate oxide (BGO) crystals, yielding high image resolution and better image quality, thus enabling physicians to visualize small lesions earlier and contributing to a more accurate disease staging and a more accurate evaluation of therapy response. The system also enables Time-of-Flight (ToF) acquisition and offers built-in capabilities to automate routine tasks in order to increase productivity and streamline workflows.

The Biograph Horizon utilizes the new iteration of the Siemens Healthineers syngo.via molecular imaging workplace image processing solution, which offers--for the first time--single photon emission computed tomography (SPECT). The new iteration offers four new features; for SPECT, organ processing for nuclear medicine helps physicians visualize and quantify the physiological characteristics of organs such as the lungs, kidneys, and stomach; For PET, tMolecular Tumor Volume (MTV) and Total Lesion Glycolysis (TLG) features enable physicians to measure the standardized metabolic activity of the entire tumor mass; and hybrid gating four-dimensional (4-D) visualization of PET and CT supports therapy planning and delivery.
