Siemens Sensation Detector Module Replacement Guide

Posted by Keith Rumley

Jan 27, 2015 9:36:53 AM

Siemens_DetectorThe Siemens Sensation family has two main detector types: those found on the 10 and 16-slice systems, and those found on the 40 and 64-slice systems. Both use a proprietary, ceramic-based material to fluoresce under exposure to X-ray. They are also both comprised of 42 modules that receive the X-ray and convert it to electronic signals.

Periodically, depending on a few factors like your room temperature and humidity and your patient volume, these detector modules will begin to degrade and fail. The following are a few tips for troubleshooting detector modules and installing your replacements.

Cone Beam CT vs. Traditional CT

Posted by David Harns

Jan 23, 2015 3:43:50 PM

Cone_Beam_CT_vs._Standard_CTWhen you think of CTs, you usually think of the GE Lightspeed, the Philips Brilliance, the Siemens Sensation, or the Toshiba Aquilion. You think 4-slice, 16-slice, or 64-slice. You think of large machines taking up an entire room and scanning patients from head to toe as they lie on a table.

Now, however, CT is much more than that. Cone beam computed tomography (CBCT) is a variation on traditional computed tomography (CT) that is on the rise. Unlike traditional CT scanners, in CBCT an X-ray tube and detector panel rotate around the patient capturing data with a cone-shaped X-ray beam instead of the “slices” CTs are typically known for.

The data received from these systems are used to reconstruct a 3D image of the following regions of the patient’s anatomy:

  • Dental (teeth)
  • Oral/ maxillofacial region (mouth, jaw, neck)
  • Ears, nose, and throat (ENT)

Philips_16_Detector_ModulesYour Philips Brilliance 16 or MX8000 IDT 16 CT scanner depends on its 42 detector modules (AKA, ADM modules) to provide crisp, clear, artifact-free images. If your image quality is starting to suffer, the modules are a reasonable suspect and some of them may need to be replaced. Of course, once you know that, the next things you begin to wonder are how often can you expect this to happen, and how much can you expect to spend?

Read on for the typical life expectancy we've seen from our Philips CT customers around the world as well as the current average prices we're seeing in the market.

Flat Panel Detector C-Arms vs. Image Intensifier C-Arms

Posted by Chris Sharrock

Jan 9, 2015 5:04:14 PM

II_vs_DetectorOver the last few years, more and more C-arm technology has begun embracing the same trends the industry has seen in interventional labs; namely, a move from traditional image intensifiers to digital flat panel detectors (FPD). As FPD options become more available, anyone considering the purchase of a C-arm is increasingly likely to be confronted with the big decision: Analog? or Digital?

Below are some aspects of C-arm hardware that buyers should bear in mind when making this choice:

RoHS Compliance: What It Means for Used Equipment

Posted by Adam Desjardins

Jan 8, 2015 12:12:36 PM

RoHS_ComplianceIf you deal with medical imaging equipment and Europe, you’ve probably heard of RoHS, and if you haven’t yet, you should do your homework, because it could mean big changes in the way you do business. RoHS stands for “Restriction of the Use of Hazardous Substances in Electrical and Electronic Equipment.” It’s the latest directive from the European Union that is meant to reduce the presence of certain substances found in all types of electronics in EU member countries. Lead, mercury, and several other materials fall under the RoHS (pronounced row-haas at the cocktail parties) directive.

How to Adjust the Steering on an OEC 9800 C-Arm

Posted by Jordan Batterbee

Dec 31, 2014 2:57:00 PM

9800_steering_adjustDo the wheels shimmy? Does the handle wiggle? Is it just getting harder to make turns? We're not talking about the tie rods on your '03 Ford Focus (there's a different blog for that). We're talking about the chain-driven steering mechanism on your OEC 9800 C-arm.

Every so often, the steering linkage in a 9800 can get a little slack in it. When this happens, it takes longer for the steering handle to engage and makes your steering sloppy. Fortunately, adjusting the chain back to its proper tension is a relatively simple task that could potentially be taken care of by your on-site maintenance team.

See the video below for a step-by-step demonstration of how an OEC 9800 steering chain can be adjusted to proper tension:

Siemens Symphony RFPA: Lifespan and Cost Info

Posted by Chad Seelye

Dec 30, 2014 11:43:01 AM

Siemens_E6_DoraEvery MRI scanner depends on its radio frequency power amplifier (RFPA) to provide proper electrical current to the system. If you use a Siemens Symphony MRI, your RFPA is the E6 Dora- a part that it shares in common with the Siemens Harmony.

Like many components in many different types of imaging equipment, the RFPA is subject to significant stress from its level of output. As a result, RFPA failures can happen suddenly and without much warning. We've already written about some reasons why your E6 Dora might fail, but what we want to share with you today is about how long (in the experience of our parts customers around the world) the typical Dora RFPA lasts and about how much (according to our recent market experience) you can expect to pay to replace one.
