Global Mobile Tomography Market, by Technology
Based on technology, the market has been divided into high slice scanners, mid slice scanners, low slice scanners, and others. Among these, the high slice scanners sub-segment accounted for the highest market share in 2021 and is estimated to show the fastest growth during the forecast period.
Global Mobile Tomography Market Share, by Technology, 2021
Source: Research Dive Analysis
The high slice scanners sub-type accounted for a dominating market share in 2021. This is due to the increasing use of high-slice scanners in the healthcare industry, as these scanners have superior diagnostic capabilities, resulting in clearer images with lower doses of radiation. This aids in detecting the root cause of a disease, which enables a timely cure of the disease detected. Furthermore, high slice scanners are suggested for advanced imaging, such as in cardiovascular testing, because it is comparatively faster, does not need to develop film images, and provide a larger imaging area. As a result, it is more suitable for people who have arrhythmias, rapid heart rates, obesity, or pediatric patients. Radiologists can use computers to improve images and detect microcalcifications that low and medium-slice CTs might overlook. The benefits of these scanners promote the growth of the mobile tomography market.
The mid slice scanners sub-type is anticipated to show the fastest growth by 2031. The mid slice scanners have lower maintenance costs which reduce the operational costs of the healthcare facilities. Also, this type of scanners has less radiation and less contrast medium which improves overall patient safety and provides high efficiency while diagnosing.

The increasing prevalence of chronic diseases, such as cancer and heart disease, is driving demand for diagnostic imaging technologies, including mobile tomography. Mobile tomography can be used to diagnose a variety of medical conditions, including head injuries, lung infections, and spinal cord injuries. The images generated by the mobile tomography device can provide doctors with valuable information about the size, shape, and location of internal organs, as well as any abnormalities or injuries present. This technology allows medical professionals to bring imaging equipment to patients who are unable to travel to a hospital or imaging center.
The demand for mobile tomography is being boosted by the convenience and portability of the technology, which allows imaging to be performed in remote or emergency settings. Additionally, the increasing prevalence of chronic diseases and technological advancements in mobile tomography is driving demand from healthcare providers who require reliable and accurate imaging solutions. The mobile tomography market is being driven by the growing need for portable and easy-to-use imaging equipment, particularly in developing countries where access to traditional imaging methods may be limited.
Newest Insights in the Mobile Tomography Market
The introduction of AI and machine learning technologies in mobile tomography devices to enhance the accuracy and speed of image analysis is boosting the mobile tomography market. As per a report by Research Dive, the global mobile tomography market is anticipated to surpass a revenue of $1,371.1 million in the 2022–2031 timeframe. The North America market is predicted to experience dominant growth in the years to come. This is because the region has a huge demand for mobile tomography due to rising chronic diseases among the elderly population in this region.
How are Mobile Tomography Market Players Responding to the Rising Demand for Mobile Tomography?
Market players are expanding their product offerings, improving product quality, increasing production capacity, and collaborating with other market players to cater to the rising demand for mobile tomography solutions. Some of the foremost players in the mobile tomography market are Canon Medical Systems Corporation, Koninklijke Philips N.V., Medtronics, Fujifilm Corporation, Koning Corporation, NeuroLogica Corp, Neusoft Corporation, Olympus Corporation, United Imaging Healthcare., Planmed Oy, and others. These players are focused on implementing strategies such as mergers and acquisitions, novel developments, collaborations, and partnerships to reach a leading position in the global market. For instance:
- In August 2020, Siemens Healthineers, a German medical device company, received clearance from the US Food and Drug Administration (FDA) for a mobile head computed tomography (CT) scanner. The scanner, known as the SOMATOM On.site, is designed to enable critically ill patients to receive CT head imaging without being moved from the intensive care unit (ICU).
- In September 2020, the Simon Hegele Group, a German logistics and supply chain management company, launched a new service that provides mobile CT scanners to hospitals and healthcare facilities. The service is designed to provide fast and flexible access to medical imaging equipment, in response to the increased demand for convenient and portable imaging solutions.
- In November 2022, NeuroLogica, a global leader in the field of point-of-care computed tomography (CT) imaging, received the US FDA clearance for the BodyTom 64 Point-of-Care Mobile Computed Tomography (CT) Scanner, a head-to-toe trauma imaging device.
COVID-19 Impact on the Global Mobile Tomography Market
The unpredicted rise of the coronavirus pandemic in 2020 significantly impacted the global mobile tomography market. One of the main factors driving demand for mobile tomography scanners during the pandemic has been the need to provide imaging services to COVID-19 patients in isolation wards and intensive care units. Mobile CT scanners have proven to be a valuable tool in the diagnosis and treatment of COVID-19 patients, allowing for faster and more accurate diagnosis of respiratory complications associated with the disease. On the other hand, the pandemic also led to the postponement of non-urgent medical procedures and reduced access to healthcare services in some regions, which has resulted in a decline in demand for mobile tomography scanners. Additionally, supply chain disruptions and restrictions on international trade have led to delays in the delivery of imaging equipment and increased costs for some customers. However, the COVID-19 pandemic has highlighted the importance of mobile imaging solutions in healthcare, and this is expected to drive demand for mobile tomography technologies in the future.
