ADMIRE – Advanced Modeled Iterative Reconstruction
"Setting new benchmarks“ VS. “Limiting solutions” – Second best is not an option.
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.
For dose reduction, Siemens already overcame this challenge with SAFIRE1, its raw-data based iterative reconstruction. SAFIRE allows up to 60%1 dose savings at a reconstruction speed so fast, many institutions use it every single examination.
But now with ADMIRE2 – Siemens‘ Advanced Modeled Iterative Reconstruction – clinical images will additionally benefit from higher resolution at organ borders and improved delineation of edges, e.g. to better localize lesions. Moreover, ADMIRE smoothly integrates iterative reconstruction in daily routine. Thick slices are now reconstructed at a more natural image impression*, even from ultra-low dose scans. With this, iteratively reconstructed low dose datasets can now easily be stored in PACS or on film.
Therefore, ADMIRE sets a new benchmark in iterative reconstruction instead of limiting its potential for clinical routine.
Exceptionally low radiation levels:
The lower the dose the more difficult it is to calculate images with an adequate image quality. This rule is common in CT. Now with ADMIRE, the next generation in iterative reconstruction, clinicians have access to enhanced image quality with a natural image impression and all clinical applications while utilizing the full dose reduction potential offered by iterative reconstruction.
Excellent image quality:
ADMIRE brings iterative reconstruction to a new level. The different strengths which can be chosen by the user improve delineation and sharpness of organs and structures. Even objects with lower density are better visible.
Of course it is important to have the images available straight after the examination, this is key for example in emergency care settings. The performance of ADMIRE makes the latest generation of iterative reconstruction routine-ready. The impact of iterative reconstruction is visible and recognizable now also in thick slices, like 3 or 5 mm slices. Normally, this is the slice thickness which will be sent to the PACS and used for reporting. Thus, ADMIRE finally makes iterative reconstruction PACS-ready.
1In clinical practice, the use of SAFIRE 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. The following test method was used to determine a 54 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogenity, low-contast resolution, and high contrast resolution were assessed in a Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file.
