The only dedicated cardiac SPECT triple-head solid-state camera

With its three high-definition, solid-state digital detectors (HDSD), the Cardius® 3XPO can perform a seven-minute stress acquisition study to speed workflow and boost efficiency. This adds up to 38% more imaging efficiency over dual-head systems, while delivering excellent image quality and resolution.

Cardius 3XPO is also designed for convenience and comfort. The open design allows upright imaging to accommodate patients up to 500 pounds, as well as bariatric, claustrophobic and COPD patients. Its compact design weighs less than 750 lbs and fits in rooms as small as 7’ x 8’ (56 sq. ft.) without the need for room shielding or architectural modifications.



The Cardius 3 XPO system offers flexibility in ways that might not be readily imagined, such as the ability to simply relocate the system to another office or room, if the need arises.

The solid-state detectors’ high count rate performance offers the reserve capacity to meet the potential demands of proposed future radiopharmaceuticals and higher speed imaging techniques.


Solid-state technology offers a whole new range of possibilities for innovations in nuclear camera design due to the fact that it is lightweight, rugged and extremely compact. The Cardius 3 XPO system packs more imaging power into a sleeker, smaller design that is more open than other system designs. It’s why Cardius systems are more patient-friendly and enable imaging patients up to 500 lbs.

The upright design makes patient ingress and egress so easy; it also offers a significant clinical advantage as the upright position lowers the diaphragm, providing better separation between the heart and viscera, and improving both clinical quality and physician confidence.


Digirad’s high-definition solid-state detectors (HDSD) offer a number of distinct performance enhancements over conventional Anger (photomultiplier tube-based) detector systems with demonstrated outstanding image quality, consistency and reliability.

Solid-state detectors are more compact, more rugged and conform better to the typical cardiac patient’s body geometry. The XPO series cameras feature HDSD detectors that raise the standard in image quality, reliability and performance to a new level for the industry and the practice of nuclear cardiology.

The XPO series pushes the envelope one step further with the introduction of another Digirad exclusive – TruACQ Count based Imaging™, the first and only count-based SPECT imaging technique that ensures consistent counts for every patient study…regardless of patient size, weight, or dose.


Every action involving the patient, set-up and operation, data processing and handling, presentation of final clinical results and reporting… all are optimized on the Cardius 3 XPO.

Digirad’s SeeQuanta™ advanced acquisition software makes performance of exams simple and efficient, while ensuring maximum consistency and quality for every patient study with less operative variability.

SeeQuanta™ features:

  • AcqSmart™ workflow tools
  • TruACQ Count-Based Imaging™ acquisition
  • User-friendly modern interface
  • Persistence ROI drawing capability
  • Seamless database integration


The small size and low weight of the Cardius 3 XPO system offers siting possibilities that are virtually off-limits for other camera designs. The system can be sited in a room as small as 7 x 8 feet (56 square feet) and can be placed on nearly any floor (weighs less than 750 pounds).

Generally no room modifications are required and the system’s electrical requirements are modest. Note: For California, as the system does not require floor mounting, no changes are required to meet OSHPD requirements. Installation can occur immediately.


Up to 38% more efficient than competitive dual-head system designs and capable of performing a 7-minute stress acquisition study, the Cardius 3 XPO offers enhanced workflow and imaging efficiency while maintaining resolution and image quality.
