Finding the correct part number is one of the most important steps when sourcing replacement parts for medical imaging equipment. Whether you are working with MRI, CT, X-ray, Ultrasound, Mammography, or Cath Lab systems, identifying the correct OEM part number can save valuable time, reduce downtime, and prevent costly ordering mistakes.
However, locating the correct part number is not always straightforward. Different manufacturers use different numbering systems, revision structures, and labeling methods.
In this guide, we explain how some of the leading OEMs structure their part numbers and what to look for when identifying replacement parts.
Why Part Numbers Matter
Many imaging components contain several numbers and various labels. These may include:
- Manufacturer references
- Supplier references
- Serial numbers
- Production batch numbers
- Regulatory information
- OEM part numbers
The OEM part number is typically the most reliable reference when sourcing a replacement component.
When contacting a spare parts supplier, providing the exact part number significantly improves the chances of receiving the correct replacement quickly.
GE HealthCare Part Numbers
GE commonly uses seven-digit part numbers.
Example:
- 5794562
Revisions are often indicated by a suffix following a dash.
Example:
- 5794562-2
In this example, "-2" represents the revision level.
GE systems may support multiple compatible replacements for the same component, so it is not unusual to encounter several interchangeable part numbers for a single application.
Certain GE modalities, particularly in X-ray and C-arm systems, may use longer numbering formats that differ from the standard seven-digit structure.
Canon Medical (Former Toshiba) Part Numbers
Canon Medical inherited several numbering conventions from Toshiba Medical Systems.
Many Canon part numbers begin with letters followed by a series of numbers.
Examples:
- PX73-10875
- BSM44-1045
- MJLC-114H
Revision information is often shown using letters.
Example:
- PX73-10875*D
In this case, "D" represents the revision level.
Canon may also use group references that further define compatibility requirements.
Example:
- PX73-10875*D Group 4
When replacing Canon components, both the revision and group designation should be checked carefully to ensure compatibility.
Philips Healthcare Part Numbers
Philips part numbers are typically easy to recognize because they consist of 12 digits.
Examples:
- 431111458742
- 431 111 458 742
Both formats represent the same part number.
In many cases, the final digit indicates the revision level of the component. This means that while two parts may appear nearly identical, the revision level can determine whether they are compatible with your system.
When sourcing Philips parts, always verify the complete part number, including the revision.
Siemens Healthineers Part Numbers
Siemens part numbers commonly consist of eight digits.
Examples:
- 07854621
- 7854621
The leading zero is sometimes omitted, creating the appearance of a seven-digit number.
Unlike some other manufacturers, Siemens often assigns an entirely new part number when a component is revised. As a result, revision history is not always visible directly on the label.
When evaluating Siemens replacements, it is important to verify compatibility through service documentation, OEM records, or an experienced spare parts specialist.
Best Practices for Identifying Imaging Parts
Before requesting a quotation, gather as much information as possible:
- OEM manufacturer
- Modality (MRI, CT, X-ray, Ultrasound, etc.)
- System model
- Part number
- Serial number of the system
- Photographs of the component
- Photos of the part label
Clear photos are often the fastest way for a supplier to verify the correct component.
What If You Cannot Find the Part Number?
Not every component has an easily visible label. Some labels may be hidden behind covers, damaged during use, or faded after years in operation.
If you cannot locate the part number:
- Take photos of all sides of the component.
- Capture any labels, stickers, or engravings.
- Provide the system model and serial number.
- Share any error messages or service logs available.
Experienced spare parts specialists can often identify components based on visual inspection and system configuration alone.
