The Attrius was developed to offer the cardiac PET imaging community an affordable choice when comparing the purchase, install and on-going maintenance of a new PET/CT system. The small design footprint enables Attrius to be placed in hospitals, imaging facilities and offices. Our system is a more reliable choice when comparing to refurbished and used PET or PET/CT systems. The Attrius provides high system uptime, minimal radiation exposure and offers a more conclusive diagnosis when compared to SPECT imaging.
New advancements in PET imaging allow for the identification of coronary flow reserve, a measurement that detects the blood flow differences between rest and stress through the coronary arteries. This information, combined with the perfusion date, can help clinicians determine whether patients will benefit from mechanical revascularization.
The cfrQuant software package we currently offer, developed by the University of Texas and K. Lance Gould, M.D., is designed to ensure effortless interpretation for today’s most challenging clinical cases.
Positron is dedicated to improving the diagnostic process in oncology, neurology, and cardiology. Our scanners are built with versatility in mind so you can image new indications as they are approved for clinical application and reimbursement.

Coronary Reserve Flow Software
Coronary Flow Reserve (CFR) is the ability of coronary blood flow to increase substantially when metabolic requirements demand it. cfrQuant, CFR quantification software, quantifies blood flow in the myocardial wall of the heart’s left ventricle in diagnostic cardiac Positron Emission Tomography (PET) imaging. CFR measurement is a key clinical application and diagnostic tool that assists in: functional assessment of intermediate stenosis, detection of critical stenosis, specific coronary artery stenosis localization, monitoring of coronary flow after revascularization procedures, quantifying post infarct blood flow, assessing coronary graft patency, identifying early or asymptomatic coronary artery disease in patients at risk and following progression or regression of CAD.
The cfrQuant software package, developed by the University of Texas and K. Lance Gould, M.D., accommodates cardiac images produced with Nitrogen-13 Ammonia or Rubidium-82 Chloride taken up by myocardium during two physiologic states: baseline (rest) and increased blood flow (stress). A mathematical model computes absolute myocardial perfusion (flow per mass of tissue, or cc/min/gm) at rest and stress. The ratio of stress-to-rest flow is termed the Coronary Flow Reserve or CFR. Visual displays of absolute flow and CFR, with their numeric quantification are presented to aid diagnostic interpretation of myocardial PET images. As a stand-alone product, the cfrQuant software package will include: PC, monitor, mouse and keyboard.
1. Simplified acquisition enhances signal/noise
characteristics since cfrQuant requires only one
frame image for the arterial input function.
2. Flow data is displayed in topographic projections
of specific coronary artery distribution to assist
3. Automount interconnect provides effortless
communication with the Attrius scanner for
speeding image transfers.
4. Processing time is only 5 minutes with no
additional protocol time required for acquisitions.
