NAEOTOM Alpha.Pro
Overview
NAEOTOM Alpha.Pro is an advanced dual-source photon-counting computed tomography (PCCT) scanner from Siemens Healthineers. It represents a significant evolution in medical imaging by directly registering each X-ray photon, enabling the acquisition of highly detailed anatomical images with functional information, reduced noise, and fewer artifacts compared to conventional CT.
This innovative system combines the precision of photon-counting technology with the speed of dual-source CT, offering ultra-high spatial resolution (down to 0.2 mm slice thickness) and spectral information in every scan at minimal radiation doses. It features fast scan speeds of up to 491 mm/sec and a temporal resolution of 66 ms, which is crucial for challenging patient groups. Embedded AI-powered productivity tools, such as myExam Companion and zero-click Recon&GO, streamline scanning workflows, optimize procedures, and automate image reconstruction to enhance efficiency and support rapid, confident diagnoses.

Use Cases
- Cardiovascular imaging (e.g., highly calcified coronary arteries, heart valves, without beta-blockers)
- Oncology (e.g., tumor development, metastases, perfusion and iodine maps)
- Pediatrics (e.g., scanning without sedation, low-dose imaging)
- Pulmonology (e.g., free-breathing scanning, reduced breath-hold)
- Neurology (e.g., stroke assessments, small cerebral blood vessels)
- Trauma and emergency care (e.g., time-critical treatments)
What Physicians Need to Know
Leverage the NAEOTOM Alpha.Pro for challenging patient populations, such as those requiring low-dose imaging (pediatrics, oncology follow-ups), patients with heavy calcifications (cardiac), or those who cannot hold their breath (pulmonology), as it offers high-resolution imaging with reduced radiation and contrast media. Utilize the AI-powered workflow tools like myExam Companion and Recon&GO to streamline scanning and reading, potentially reducing scan times and manual post-processing, leading to faster diagnoses and improved patient throughput. The intrinsic spectral imaging capabilities can provide additional functional information in every scan, enhancing diagnostic confidence for complex cases.
The NAEOTOM Alpha.Pro offers seamless integration with existing PACS solutions, exemplified by its partnership with Sectra, allowing radiologists to access and post-process advanced photon-counting CT images directly within their diagnostic application. This eliminates the need for switching between multiple workstations or applications, thereby optimizing workflow efficiency and data management within the radiology department.
