Selecting the right CT scanner is one of the most important equipment decisions for any healthcare facility. This guide covers everything from slice count selection to brand comparisons and total cost of ownership.
Slice Count Selection
The number of slices determines the scanner's capabilities:
- 16-slice: Budget-friendly, suitable for general radiography and emergency departments
- 64-slice: Versatile, good for cardiac imaging and routine body scans
- 128-slice: Advanced, ideal for cardiac CT angiography and neurology
- 256+ slice: Premium, for research institutions and high-volume centers
Key Specifications
Beyond slice count, consider:
- Gantry bore size (70cm standard, 80cm for bariatric patients)
- Table weight capacity (150–300 kg)
- Rotation speed (0.28–0.5 seconds)
- kV range (70–140 kV for dose optimization)
- AI integration capabilities
Chinese vs Global Brands
| Feature | Chinese Brands | Global Brands |
|---|---|---|
| Price | $80K–450K | $180K–900K |
| Quality | Comparable | Established |
| AI Integration | Bundled options | Premium add-ons |
| Service Network | Growing | Extensive |
| Lead Time | 30–60 days | 60–120 days |
Top Chinese Manufacturers

AI Integration Options
Modern CT scanners increasingly bundle AI capabilities:
- Image reconstruction: Reduces noise and improves image quality at lower doses
- Automated diagnosis: Chest CT triage, stroke detection, cardiac analysis
- Workflow optimization: Automated positioning, scan planning, and reporting
Leading AI providers: Infervision, United Imaging uAI, Arterys, Aidoc
Installation Requirements
Before purchasing, verify:
- Room dimensions (minimum 25–35 m² for scanner room + control room)
- Power supply (dedicated circuit, typically 30–50 kVA)
- HVAC requirements (temperature 18–24°C, humidity 30–60%)
- Lead shielding installation
- IT infrastructure (PACS/RIS integration)
Total Cost of Ownership
The purchase price is only part of the equation:
- Installation: $20,000–$80,000 (including room prep and shielding)
- Annual maintenance: $15,000–$40,000 (10–15% of purchase price)
- Consumables: Contrast media, calibration phantoms
- Software licenses: AI packages, advanced visualization
- Training: Technician and radiologist training
- Floor space: Opportunity cost of dedicated room
Budget 1.5–2x the purchase price for first-year total cost.
