ADMIRE – Advanced Modeled Iterative Reconstruction
In modern healthcare patients deserve the lowest possible dose and radiologists desire the best image quality in daily routine. This is known as ALARA – the paradigm to delivery diagnostic image quality at a dose as low as reasonably achievable. But the big challenge is to realize this in daily routine, e.g. time crucial settings like acute care, making many institutions step away from iterative reconstruction here.
ADMIRE is the latest innovation in iterative reconstruction.
Clinicians need to be able to reduce doses¹ and use iterative reconstruction in their daily routine. Advances in software and hardware have led to innovative algorithms and techniques that greatly reduce radiation and produce natural image impressions.² Raw-data statistical modeling is a new approach to minimizing artifacts. Rather than focusing on one detector element for defining the data, ADMIRE also evaluates data from surrounding elements. In addition, noise cancellation in the image space keeps noise lower than ever. Large-scale analysis in all directions separates anatomical structures from the noise, and results in excellent image quality. High processing power enables superb reconstruction performance, so ADMIRE can fit into daily routines and create reader-ready reconstructions on the fly with the desired image impression.
Exceptionally low radiation
The general rule in CT is that lower doses make it harder to reconstruct images of sufficient quality. But now, ADMIRE is changing that. ADMIRE can be used in all clinical applications, and achieves enhanced image quality and natural image impressions² at dose levels lower than ever before.¹
Excellent image quality
ADMIRE takes iterative reconstruction to a new level. Users can choose various strengths for outstanding delineation and sharpness of organs and structures in the body. ADMIRE even makes it easier to distinguish lower-density structures and greatly reduces artifacts.
Suitable for daily use
Clinicians need images to be available right after a scan, especially in settings such as emergency medicine. As a high-performance system, ADMIRE can easily integrate into daily routines. The benefit of iterative reconstruction is now also visible with thick (e.g. 3 mm) slices. As this is the thickness normally sent to PACS and used for reporting, ADMIRE has finally made iterative reconstruction PACS-ready.

Equivalent low contrast detectability can be achieved with 80% to 85% less dose using ADMIRE at highest strength level for thin (0.6 mm) reconstruction slices in measured and simulated body and head phantoms for low contrast objects with different contrasts. See ADMIRE data sheet for further information.
In clinical practice, the use of ADMIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
