Somatom go.All/go.Top/go.Fit Machine and Spare Part

Update time：2025-10-21

In the rapidly evolving field of medical imaging, computed tomography (CT) scanners play a pivotal role in diagnosing and treating a wide array of conditions, from routine check-ups to complex interventions. Siemens Healthineers' SOMATOM go. platform stands out as a versatile, scalable solution designed to meet diverse clinical needs while prioritizing patient comfort, operational efficiency, and dose optimization. Among its key models—SOMATOM go.All, go.Top, and the entry-level SOMATOM go.Fit (often aligned with the go.Up variant in documentation)—these scanners offer a spectrum of capabilities tailored to different healthcare settings. This article explores their features, differences, clinical applications, and the critical aspect of spare parts management, drawing on Siemens' innovative technologies like AI-powered automation and mobile workflows.

Overview of the SOMATOM go. Platform

The SOMATOM go. platform, developed in collaboration with the medical community, emphasizes "made to match" adaptability. It integrates advanced features such as myExam Companion for AI-guided workflows, Mobile Workflow for tablet-based control, and technologies like TwinBeam Dual Energy and SAFIRE for low-dose imaging. All models share a 70 cm gantry aperture for patient comfort, support up to 307 kg table loads, and incorporate GO technologies for automated scan preparation.

These scanners address key challenges: rising patient volumes, workforce shortages, and the need for advanced procedures without overwhelming complexity. From routine screenings to cardiac and trauma imaging, the platform reduces scan times and radiation exposure while enhancing image quality.

Key Models: SOMATOM go.All, go.Top, and go.Fit

SOMATOM go.All: Beyond Routine Capabilities

The SOMATOM go.All is positioned as a mid-tier workhorse, unlocking advanced procedures while excelling in daily routines. With 64 slices (32 × 0.7 mm z-coverage), it achieves rotation times as fast as 0.33 seconds and a generator power of 75 kW (upgradable to 80 kW). Key specs include a maximum scan speed of ~150 mm/s, an Athlon 7.0 MHU X-ray tube, and kV settings from 70-140 for optimal low-dose protocols.

In practice, go.All shines in cardiac imaging (e.g., 8.2-second scans at 110 kV with CTDIvol of 10.38 mGy) and oncology follow-ups. It's ideal for mid-sized clinics handling mixed caseloads, offering flexibility for occasional advanced tasks like perfusion studies without the full overhead of high-end systems.

SOMATOM go.Top: The Clinical Allrounder

For facilities demanding versatility, the SOMATOM go.Top elevates performance with 128 slices (64 × 0.6 mm z-coverage), enabling broader anatomical coverage and faster scans—up to 175 mm/s. It mirrors go.All's 75 kW power and 0.33-second rotations but adds superior handling for high-throughput environments, such as emergency departments.

A standout example is its 16-second full-body scan at 70 kV (CTDIvol: 6.37 mGy, DLP: 389 mGy cm), making it perfect for trauma, interventional procedures, and dual-energy applications like gout detection or tumor characterization. The model's Guide&Go integration supports tablet-guided biopsies, enhancing precision and patient interaction.

SOMATOM go.Fit (go.Up Variant): Entry-Level Efficiency

The SOMATOM go.Fit, akin to the go.Up in Siemens' lineup, serves as an accessible entry point for budget-conscious or space-limited settings. It features 64 slices but with modest specs: 32 kW generator, 0.5-second rotations, Chronon 3.5 MHU tube, and max mA of 240 (upgradable to 400). Scan speeds hover around 100 mm/s, with kV limited to 80/110/130.

This model excels in basic routines like chest/abdomen screenings, prioritizing ease of use and low maintenance. It's a smart starter for primary care or mobile units, with the platform's shared software allowing future upgrades to go.All or go.Top without full replacement.

Differences Between the Models

While all models leverage the go. platform's core innovations, their distinctions lie in performance tiers, catering to evolving clinical demands. Below is a comparison table highlighting key specs:

Specification	SOMATOM go.All	SOMATOM go.Top	SOMATOM go.Fit (go.Up)
Slices	64 (32 × 0.7 mm)	128 (64 × 0.6 mm)	64 (32 × 0.7 mm)
Rotation Time	0.33 s	0.33 s	0.5 s
Generator Power	75 kW (up to 80 kW)	75 kW (up to 80 kW)	32 kW
Max Scan Speed	~150 mm/s	~175 mm/s	~100 mm/s
X-ray Tube	Athlon 7.0 MHU	Athlon 7.0 MHU	Chronon 3.5 MHU
Max mA	625 (up to 825)	625 (up to 825)	240 (up to 400)
kV Range	70-140	70-140	80/110/130
Clinical Focus	Routine + advanced (e.g., cardiac)	All-rounder (trauma, intervention)	Basic routines (screenings)
Upgrade Path	Seamless to go.Top	N/A (top-tier)	To go.All/go.Top

In essence, go.All bridges routine and advanced needs, go.Top maximizes flexibility for complex cases, and go.Fit focuses on affordability and simplicity. All support AI automation, reducing technologist time by up to 30% and dose by 60% via adaptive protocols. More spare part detail as below :

Clinical Applications and Benefits

These models adapt to diverse scenarios:

Routine Screening: go.Fit handles high-volume basics efficiently.
Cardiology/Oncology: go.All's speed ensures low-dose heart scans.
Emergency/Trauma: go.Top's wide coverage excels in polytrauma assessments.
Interventional: Mobile Workflow across models enables real-time guidance.

Benefits include patient-centric design (e.g., quiet scans, wide bore) and sustainability through modular upgrades, extending equipment life amid resource constraints.

Spare Parts and Maintenance: Ensuring Uptime

Reliable spare parts are vital for minimizing downtime in CT operations, where even brief interruptions can delay critical diagnoses. Siemens Healthineers offers robust support via its global Spare Parts Services, including regional warehouses for rapid delivery of OEM components. Tailored packages optimize inventory, supporting circular economy principles by refurbishing parts.

For the go. platform:

Common Parts: X-ray tubes (e.g., Athlon/Chronon), detectors, generators, and software modules are interchangeable where possible.
Availability: Parts like go.All's Athlon tube or go.Top's high-mA upgrades are stocked for 24-48 hour shipping.
Third-Party Options: Providers like Mediram offer tested spares with 90-day warranties, including detectors and gantry components, packed for quick integration to cut downtime.
Maintenance Services: Siemens' teamplay fleet management monitors predictive needs, while scalable partnerships enhance in-house engineering. Annual checks focus on tube life (up to 7 MHU) and dose calibration.

Proactive parts management—via Siemens' digital tools—can reduce costs by 20-30% and extend system longevity.

Conclusion

The SOMATOM go.All, go.Top, and go.Fit represent a smart ecosystem for modern CT imaging, balancing performance, scalability, and accessibility. From go.Fit's cost-effective entry to go.Top's all-encompassing prowess, these machines empower healthcare providers to deliver precise, patient-focused care. Coupled with Siemens' comprehensive spare parts ecosystem, they ensure operational resilience in an era of increasing demands. As clinical needs evolve, investing in the go. platform means future-proofing your facility—consult Siemens Healthineers for tailored demos or service plans to match your workflow.
