Global Computed Tomography Market– A Boon in Medical Imaging
Computed tomography (CT) is a computerized X-ray imaging procedure. CT scanners uses motorized X-ray source as compared to conventional X-rays, which uses X-ray tube, fixed at a point. Cross sectional images or slices are generated through the computer for assessment of the signals produced. The slices also known as tomographic images contain more information than conventional X-rays. 3-D images of the patient enables surgeons, easier identification, location of the basic structures, and possible abnormalities or tumors in the body. Dense structures in the body are easily imaged as compared to soft tissues, because X-rays passes easily through softer tissues, producing faint images. To contain this drawback, intravenous (IV) contrast agents are used. For instance, to examine the possible obstructions in the circulatory systems, a contrast system based on iodine is injected in the blood vessels and barium-based compounds are used as oral contrast agents for imaging organs in the digestive system.
Growth of the computed tomography market is primarily driven by increasing product innovation, increasing research and development activities and growing awareness about the non-invasive technologies. For instance, in December 29, 2017 the Median Technologies announced a research agreement with Xingtai people’s Hospital to provide company’s proprietary MediScan image analysis technology for the screening of lung cancer in the Xingtai city. Earlier, in April 2017, Toshiba Medical, upgraded its Aquilion Lightning 80 CT system (Aquilion). Aquilion is designed to produce high resolution images to help surgeons with faster disease diagnoses and treatment.
The global computed tomography market was valued at US$ 5,021.6 million in 2016 and is expected to exhibit a robust CAGR of 5.2% over the forecast period (2017–2025).
Global Computed Tomography Market Revenue (US$ Mn), by Region – 2016
North America is expected to be dominant in the global computed tomography market over the forecast period
North America accounted for the largest share in the global computed tomography market, followed by Europe in 2016. This is attributed to increasing prevalence of cancer in the region and a large number of skilled healthcare professionals. For instance, according to American Cancer Society, in 2015, approximately 1.7 million new cases of cancer were diagnosed in the U.S.
Additionally, according to the World Health Organization (WHO), around 17.7 million people across the globe died due to cardiovascular disorders. Early detection with diagnostic systems such as the CT scans could aid in reducing the incidence of these disorders. Thus, increasing adoption of computed tomography for providing better diagnostic solutions and to detect abnormalities and fractures in the body is a factor expected to drive growth of the market over the forecast period.
Collaborations, and agreements driving the growth of computed tomography market
The players in the computed tomography market are collaborating with innovative solutions providers to drive growth. For instance, in November 2017, the Sectra Corporation (Sectra), an international medical imaging information technology company signed a distribution agreement with El Seif Development Company (El Seif). According to the agreement El Seif will distribute Sectra’s enterprise image management solutions, which comprise of picture archiving and communication system (PACS) for image sensitive procedures such as breast imaging, orthopedic and cardiovascular procedures. With this healthcare providers (2,300 primary care centers and 470 hospitals) in Saudi Arabia, will gain access to the Sectra’s in proprietary imaging solutions. In January 2017, Bruker microCT (Bruker), subsidiary of Bruker Corporation and iTomography Corporation (iTomo) entered into a multiyear license agreement for the software technology developed by iTomo. This provided Bruker with non-exclusive rights to the software developed through iTomo’s image reconstruction algorithm.
Key players in the global computed tomography market include GE Healthcare, Siemens Healthineers, Hitachi Medical Corporation, NeuroLogica Corporation, Philips Healthcare, Toshiba Medical Systems, Neusoft Medical System, and Shenzen Anke High-Tech Co. Ltd.
Computed Tomography (CT) or computed axial tomography is an imaging technique that uses different combinations of X-ray images formed via different angles leading to cross sectional images of specific internal organs and tissues. Computed tomography is used mainly to detect coronary artery diseases, guided biopsy and screening of blood clots, blood vessel aneurysm, calcification, internal bleeding, infarction, brain and head injuries, fractures, and uncontrolled and abnormal cell growth in patients suffering from cancer. As compared to conventional 2D radiography, CT is offers better imaging. Conventional radiographers use X-rays in the form of electromagnetic radiation produced through X-ray tube. The images produced are blurred compared to CT scanners. CT scan eliminates the superimposition of images surrounding the area under inspection. Moreover, computed tomography also produces high resolution images, which differentiate organs or tissues based on their physical intensities. The advanced versions of CT with high resolution images has led to development of CT angiography, and CT colonography. CT angiography does not use insertion of catheter and CT colonography is more accurate technique for detection of tumors with lower radiation dose. CT colonography is widely used in the U.K and the U.S for the screening of colon polyps and colon cancer. According to the Cancer.org in 2017, there will be 39,910 new cases of rectal cancer and 95,520 new cases of colon cancer in the U.S alone.
Key players in the market are focusing on launching new products and upgrading its products, which in turn is expected to aid in growth of the market. For instance, in April, 2017, Toshiba Medical, upgraded its Aquilion Lightning 80 CT system (Aquilion). Aquilion is designed to produce high resolution images to help surgeons in faster disease diagnoses and treatment. Moreover, in May 2017, UC Davis Comprehensive Cancer Center (UC Davis) signed a licensing agreement with Isotropic Imaging Corporation — a wholly owned subsidiary of Canada-based Isotropic Corporation — to market CT scanner developed by UC Davis.
The CT scan market is primarily driven by increasing prevalence of cardiovascular diseases, cancer and orthopedic disorders, and increasing geriatric population. According to the National Institute of Health (NIH), in 2016, 8.5% people are aged 65 and over, which is expected to reach 17% of the total global population by 2050. Stringent regulatory framework and product recalls are major factors hindering growth of the computed tomography market. For Instance, in June 2017, GE Healthcare recalled its GE Healthcare Optima CT660, CT680 X-ray system. The reason of recall was defect in its software system.
