QRM
QRM has a legacy spanning over 25 years in the design and manufacturing of phantoms for diverse medical imaging modalities. Initially focusing on lung imaging in CT and bone densitometry in DXA and CT, the company has since broadened its catalog to include numerous products utilized in clinical routines, research, development, and scientific applications. QRM specializes in customized phantoms tailored for diagnostic X-ray, CT, and micro-CT imaging, assisting in tasks such as image quality analysis, HU-level calibration, and dosimetry. Their anthropomorphic phantoms simulate anatomical structures, easing the process and minimizing the need for human volunteers during medical device testing. Leveraging high-quality tissue-equivalent materials and the latest manufacturing technologies, QRM ensures that each phantom undergoes rigorous quality control specific to its intended imaging modality, such as DXA, CT, C-arm, Micro-CT, and MRI. Adhering to ISO 9001:2015 standards, the company's quality management system underscores their commitment to precision and reliability.

About QRM
We look back on more than 25 years of experience in designing and manufacturing phantoms for medical imaging modalities. Our first products were designed for lung imaging in Computed Tomography (CT) and bone densitometry in DXA and CT.
Since starting manufacturing phantoms in the early '90s, our range of phantoms has increased substantially over the years. Today, we offer products for different imaging modalities in clinical routine, research, development and science, as well as customized and OEM products.
Our core competence: customized phantoms
Our engineers design dedicated phantoms for many applications in the field of medical imaging. Our customers are physicians, scientists and manufacturers all over the world. Interested? You are welcome to contact us for further information.
Our main focus is on developing products for diagnostic X-ray, CT and micro-CT imaging. We offer phantoms to analyze image quality (IQ), calibrate HU-levels as well as for dosimetry issues.
High Quality Tissue Equivalent Materials
Anthropomorphic phantoms are physical test objects simulating anatomical structures of the body, which makes them easier and more convenient to use. Some phantoms provide equivalent properties as the real human body does, e.g., organs, such as lung, liver, fat, bone. This is an advantage in X-ray imaging due to dose issues – medical devices can be thus tested without using human volunteers.
Physical parameters of such devices can be tested as well in a more physical or technical way, for example the spatial resolution of a system can be tested with a wire in a cylindrical phantom to create a MTF, or with a high resolution bar pattern as well for visible testing.
Professionally designed and manufactured with highest precision
QRM phantoms are professionally designed and manufactured with highest precision. The components are carefully selected and adapted to the specific imaging modality.
Our machinery uses the latest technology to produce and manufacture phantoms with high accuracy.
Standard as well as custom-made phantoms undergo a quality control test according to their use. Therefore, different types of medical imaging devices (e.g. DXA, CT, C-arm, Micro-CT, MRI, etc.) are used for our test setups.
What are Phantoms?
Imaging phantoms or simply 'phantoms' are specially designed objects that are scanned or imaged in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices. These objects are more readily available and provide more consistent results than the use of a living subject or cadaver, and likewise avoid subjecting a living subject to direct risk.
Phantoms were originally employed for use in 2D X-ray-based imaging techniques, such as radiography or fluoroscopy, though more recently phantoms with desired imaging characteristics have been developed for 3D techniques, such as MRI, CT, Ultrasound, PET, and other imaging methods or modalities.
A phantom used to evaluate an imaging device should response in a similar manner to how human tissues and organs would act in that specific imaging modality. For instance, phantoms made for 2D radiography may hold various quantities of X-ray contrast agents with similar X-ray absorbing properties to normal tissue to tune the contrast of the imaging device or modulate the patient's exposure to radiation.
In such a case, the radiography phantom would not necessarily need to have similar textures and mechanical properties since these are not relevant in X-ray imaging modalities. However, in the case of ultrasonography, a phantom with similar rheological and ultrasound scattering properties to real tissue would be essential, but X-ray absorbing properties would not be needed.
