Spectrum Dynamics Medical has introduced EMAC (emission map attenuation correction) to its digital SPECT (D-SPECT) cardiac scanner. The patient-specific software application seeks to remove perceived issues and provide solutions in SPECT myocardial perfusion imaging, including attenuation artefacts, scatter, quantification accuracy, additional scanning and patient radiation exposure.
“Clinicians today are looking for solutions that provide diagnostic results on their terms,” explained vice president of research and development Nathaniel Roth. “That means anything presented needs to prevent additional imaging times and, even more critical, dose to the patient. The state-of-the-art analytical methodology implemented for EMAC provides clinicians with a unique image quality improvement to overcome attenuation artefact hurdles, without any additional radiation dose or changes to D-SPECT scanner imaging workflow.”
EMAC utilises a four-step process to provide results. By first accessing patient-specific SPECT data, EMAC develops various models to estimate an emission map. Reconstructed SPECT data is then matched with the emission map for attenuation correction, ultimately meaning better results without additional scanning or changes to the workflow. It is available for all D-SPECT series digital cardiac scanners.
“Cardiac imaging is a continually evolving field and we are committed to investing in the appropriate technologies for the best patient outcomes,” added Roth.
