Making It Easy to Find Medical Imaging Part Numbers

It can be confusing to locate the part numbers on different medical imaging brands in the industry. In this blog, we show you how to locate medical imaging part numbers on 4 of the top brands – Philips, Siemens, GE, and Canon (former Toshiba).

By the end, you will become more confident and will better understand how these original equipment manufacturers (OEMs) display their part number references.

Let us begin.

When replacing a spare part on medical equipment, the part number is the best and most accurate information to locate your systems’ replacements.

Generally, many medical imaging parts like electronic boards, cable, generators, etc. can have many different numbers attached and/or imprinted. This is because most parts are produced by other suppliers for the OEMs, and therefore, can have many different medical imaging part numbers.

In the following section, we show you how Philips, Siemens, GE and Canon label their parts. And also, what tips and tricks you can apply when locating the correct replacements on your medical equipment.

Keep in mind that this distinction applies to most cases, but some exceptions may occur.

Philips Healthcare Part Numbers

When looking at Philips part numbers, no matter it is a CT scanner, MRI scanner, or an ultrasound, they always consist of 12 digits. The first 11 digits normally refer to the spare part itself and the last digit refers to the revision of it.

However, in most cases, the medical imaging part number is displayed as one of the following two examples:

4522 117 73553 or 452211773553

These two options mean the exact same thing. Some part number (PN) labels will have the revision highlighted:


It makes it easier to see that this part is a revision 3. This information could indicate that if revision no. 3 is installed on your system, revision 1 or 2 will not work for you, while a revision 4, 5, or 6 might.

So, hopefully now it is easy to orient yourself among Philips medical imaging parts.

Let’s look at Siemens.

Siemens Healthineers Part Numbers

Just like in Philips’ case, Siemens’ part numbers do not differ depending on whether it is a part for CT, MRI, ultrasound, or any other medical equipment. Their part numbers always consist of eight digits.

When talking about Siemens, the first digit is often zero, for example:


However, in some cases, this (0) can be missing. Hence, the part number could look like it is only seven digits:


What makes Siemens part numbers interesting?

Their revisions are not visible in the PN labels. Siemens gives completely new part numbers to their parts when they update them with a new revision.

Therefore, first check the description of the alternative part, and if the description is the same as for the part you are looking for, it is a good start. But you will have to check Siemens’ manual or get in touch with an experienced technician or spare parts specialist to check if it is compatible with your system.

You cannot be sure that it is compatible unless you investigate the revision of the system and clarify whether the part number that you have been offered is compatible.

GE Healthcare Part Numbers

GE Healthcare displays their part numbers with seven-digit numbers. For example:


When GE displays the revision of the spare part, they use a dash followed by the revision number:


In this case, the revision is 2. This could indicate that revision 2 is installed on your system, and revision 1 will not work for you, while revision 3, 4, or 5 might. GE often has many compatible options available for the same part. This means that you could be able to find four, five, or even more medical imaging part numbers that could be compatible with your equipment.

On some X-ray modalities, such as C-arms, the part numbers differ from the normal seven-digit numbers. Here you need to look for a 10-digit number. These are very distinctive, see below:


Therefore, be extra cautious when looking at your GE X-ray part numbers.

Canon Medical Part Numbers

Canon Medical part numbers have different looks due to the acquisition of Toshiba Medical. However, there are some general rules that apply to Canon part numbers. They have letters at the beginning of the part numbers, which may be easier to notice.

Generally, Canon part numbers have nine-digit numbers that could be displayed with either two or three letters at the beginning:

PX74-10473 or BSM43-1065

The parts numbers of Canon MRI coils and other accessories may start with four letters and end with a letter:


Canon uses letters for revisions, and thus a revision is usually displayed with an asterisk and a letter:


Revision C indicates that if revision C is installed on your system, revision A or B will not work for you. On the other hand, a revision D, E, or F might.

Furthermore, Canon also uses Group references, which means that a PX74-10473*C could also look like:

PX74-10473*C Gr. 3

Here the same rule applies to revisions. If Group 3 is installed on your system, Group 1 or 2 will not work for you, while Group 4, 5, or 6 might.
