Spectrum’s RFID-Reading Cardiac Camera Performs Patient Check-In at Scanner

Spectrum Dynamic’s D-SPECT cardiac camera is reportedly built around implementation of solid state CZT detector technology.

This design employs 10 independent CZT detectors that move back and forth to collect cardiac images from hundreds to thousands of different angles, said the company. This implementation reportedly offers up to a factor of 10 improvements in sensitivity over a conventional NaI-based system.

The system is reportedly optimized to solely produce cardiac images through integration of hardware and software. When patients register, their personal data is collected on an RFID tag located on a patient bracelet. The tag is encrypted with patient information, including height and weight, which is used to calculate a body mass index. Before injecting the radiopharmaceutical, a separate RFID tag on the syringe uploads information about the dose and activity to the patient bracelet. Once the patient sits in the camera to be imaged, the patient and syringe data encrypted in the bracelet is picked up by an antennae on the arm of the chair, and the acquisition parameters for the camera are optimized based on the patient’s anatomy and physiology, said the company.
