Siemens Healthineers Molecular Imaging has completed a major $43.6 million construction and renovation project at its PET Detector Center in Rockford, Tennessee, strengthening the company’s manufacturing and research capabilities for positron emission tomography (PET) technology. The investment expands the company’s footprint at the Rockford campus, increases dedicated manufacturing capacity and supports the development and production of PET detectors used in Siemens Healthineers’ PET/computed tomography (PET/CT) systems.
The completed project adds approximately 40,000 square feet to the existing 97,000-square-foot Rockford campus while also renovating 7,500 square feet of existing facilities. The expansion is designed to help Siemens Healthineers respond to growing global demand for PET/CT imaging, as healthcare providers increasingly use molecular imaging in cancer care, neurology and cardiovascular medicine.
The Rockford facility holds a particularly important position within Siemens Healthineers’ global molecular imaging operations. It is the company’s sole manufacturing site worldwide for the PET detectors that form a critical component of its PET/CT scanners. By expanding production capabilities at the location, Siemens Healthineers aims to increase its ability to manufacture these detectors and support customers in the United States and international markets.
Expanding PET Detector Manufacturing Capacity
PET imaging has become an increasingly important technology in modern medical diagnostics because it can provide clinicians with information about biological and metabolic processes occurring inside the body. Unlike imaging technologies that primarily show anatomical structures, PET can help visualize metabolic activity, allowing physicians to identify and evaluate abnormalities associated with a range of diseases.
Siemens Healthineers’ PET detectors play a central role in this process. During a PET examination, a patient receives a radiopharmaceutical that emits gamma rays as the substance undergoes radioactive decay. The PET detector captures these signals, and the resulting information is processed by the imaging system to generate detailed images that can help clinicians understand disease activity.
The expanding use of radiopharmaceuticals is one of the factors contributing to increased demand for PET/CT technology. In oncology, PET imaging can support the detection, characterization and monitoring of many cancers. In neurology, molecular imaging is being used in applications such as the evaluation of Alzheimer’s disease. PET also has applications in cardiac imaging, where metabolic and functional information can complement other diagnostic techniques.
Another important area of growth is theranostics, an approach that combines diagnostic imaging with targeted therapeutic strategies. As the clinical use of radiopharmaceuticals continues to develop, demand for imaging systems capable of detecting and characterizing molecular activity may increase further.
The Rockford expansion is intended to position Siemens Healthineers to respond to these trends by increasing the company’s ability to produce PET detectors at scale.
A Major Investment in the Rockford Campus
The Rockford PET Detector Center encompasses multiple facilities located on Dunavant Drive and Stock Creek Boulevard. The recently completed construction and renovation project focused on the Dunavant Drive portion of the campus.
One of the largest components of the investment was the creation of approximately 36,000 square feet of additional dedicated manufacturing space. The new area provides Siemens Healthineers with additional room to expand PET detector production and improve its ability to meet customer requirements.
The project also included the renovation of approximately 7,500 square feet within the existing 26,000-square-foot PET detector manufacturing and engineering facility. The upgraded space is intended to support increased manufacturing capacity and strengthen the operational capabilities of the facility.
In addition, Siemens Healthineers expanded its research and development infrastructure by approximately 4,000 square feet. The expansion involves the company’s existing 21,000-square-foot R&D facility and provides additional capacity for research and engineering activities related to molecular imaging technologies.
The company’s 50,000-square-foot crystal manufacturing facility on Stock Creek Boulevard was not included in the construction and renovation project.
Together, the new construction and renovations provide a substantial increase in the operational footprint of the Rockford campus. The improvements are expected to support manufacturing, engineering, research and management activities as Siemens Healthineers continues to develop and commercialize molecular imaging technologies.
Supporting New PET/CT Product Lines
The increased production capacity is expected to play a role in the launch of new PET/CT product lines in both the United States and international markets.
PET/CT combines two imaging modalities. PET provides functional and metabolic information, while computed tomography (CT) produces detailed anatomical images. Combining these capabilities allows clinicians to correlate areas of increased biological activity with specific anatomical structures.
The technology has become an important tool in numerous clinical settings, particularly oncology. Physicians can use PET/CT imaging to assess disease activity, help determine the extent of disease and monitor how a patient responds to treatment.
The technology is also increasingly relevant as new radiopharmaceutical applications emerge. As the number of molecular imaging applications grows, manufacturers must be able to supply imaging systems and components capable of supporting expanding clinical demand.
For Siemens Healthineers, increasing PET detector production is therefore not simply a manufacturing expansion. It is also intended to support the company’s broader molecular imaging strategy and enable customers to access PET/CT technology as clinical applications continue to develop.
James Williams, PhD, head of Siemens Healthineers Molecular Imaging, described the project as an important investment in the company’s position in PET/CT technology. He said the expansion demonstrates Siemens Healthineers’ continued commitment to global leadership in the field while significantly increasing production capacity and customer access to PET/CT scanners.
Williams also recognized the role of the state of Tennessee in supporting the investment through its economic development program.
