We re-engineered SPECT/CT bone imaging to use CT as the frame-of-reference during image reconstruction. The higher image resolution achieved from xSPECT Bone™ technology enables you to better localize and characterize disease for a more accurate representation of each patient’s condition.

As patient populations continue to age, the growing presence of metal implants and pacemakers adds complexity to imaging. iMAR, our CT metal-artifact-reduction technique, helps improve both CT and SPECT attenuation correction in these cases.2 xSPECT Bone and iMAR can easily be combined for even greater image clarity.

For quick and conclusive answers to clinical questions, you need the best image for each patient. However, striking the right balance between image quality and radiation dose can be a challenge, particularly given today’s diverse patient population. Our proprietary CT image reconstruction software and hardware, SAFIRE, lets you accomplish this—quickly and easily.3
