Spectral Computed Tomography(CT) Market Overview
Spectral computed tomography (CT) is a scanning device that is used for medical imaging for diagnosis in case of cancer, tumor development, cardiovascular impairment, aneurysm and other bone related disorders. Spectral CT has been considered as the next phase of the widely accepted computed tomography (CT) providing an effective imaging modality. The computed tomography reconstructs an object's internal structure, from a sequence of X-ray transmission images. Computed tomography functions by detecting the number of photons that hits the detector and attenuation in relation to the photons emitted by the X-ray tube that does not interact with the body. However, these detectors do not differentiate among the varied frequencies of the photons and provide monochromatic reconstructed image. These limitations of conventional CT support the development of spectral CT, leading to an increase in the growth of the overall spectral CT market.
The novel spectral CT is based on dual energy, that measures both low and high energy photons during the absorption and scattering of X-rays, resulting into the formation of different energy bands. The body tissues absorb energy bands differently and hence any changes observed in these energy bands help in diagnosis of changes within the body. Spectral CT forms spectral base images and improves visualization of these constructs. This has been accepted by radiologists and clinicians for diagnosis throughout the medical industry by helping them investigate not only anatomy visualization but also tissue characterization.
The global spectral CT market is segmented based on product type, application, type, technology, and end user. On the basis of product type, the market is segmented into spiral CT, electron beam tomography, and multi-slice computed tomography.
On the basis of application, the market is categorized into cardiovascular, neurovascular, spinal, musculoskeletal disorder and others. Based on type, the segments include cardiac imaging, neutral imaging, clinical imaging and others.
The spectral CT market is segmented into dual layer detector and gemstone spectral imaging detector, based on technology. Globally, the demand for spectral CT products was largest in hospitals and is expected to remain so during the forecast period 2017-2023, due to the increasing prevalence of diseases such as cancer, cardiovascular disorders and neurological disorders. Other key end user in the spectral CT market include private clinics, diagnostic and imaging center; academic institutes and research center; and others.
Spectral Computed Tomography(CT) Market Dynamics
The spectral CT market size is expected to grow significantly during the forecast period. The major factor driving this growth include the preference for spectral CT over conventional CT, since spectral CT offers comprehensive application base and constructs superior spectral derived images. Moreover, with the growing geriatric population, there has been increase in number of age-related disease. Additionally, unhealthy lifestyle has also led to an increased prevalence of chronic diseases. All the aforementioned factors are expected to drive the growth of the global market. Further, research in the field of unknown and rare diseases demand higher imaging and resolution techniques that are expected to favor the growing market of spectral CT.
The installation cost of the device and the computation of the resultant imaging and harmul impact of X-rays to human body are key factors restraining the growth of the spectral CT market. Additionally, the spectral CT process is complex and requires skilled professionals, thus posing a restraint to the growth of the market.
The spectral CT is an evolving field and holds potential in several applications that are yet to be explored, such as–mammography, oncology and emergency department. In March 2015, Koninklijke Philips N.V. collaborated with University of California to investigate applications of spectral imaging in mammography. Similarly, other manufacturers are also investing in R&D to explore several other clinical applications of spectral CT.
Spectral Computed Tomography(CT) Insights by Geography
North America holds the largest share of the global spectral CT market due to rise in geriatric population and increasing prevalence of diseases in the region. The ease of accessibility to advanced technologies is expected to make North America leading the spectral CT market followed by Europe. Asia-Pacific is expected to witness the fastest growth due to the rising awareness among the population with respect to healthcare and consequent increase in healthcare expenditure.
Spectral Computed Tomography(CT) Competitive Landscape
The key players across the globe, are launching products to gain a leading position in the spectral CT market share.
In February 2017, GE Healthcare announced the FDA approval of its GSI Xtream on Revolution CT, first of the volume spectral CT technology, that claims improved detection, tissue characterization and metal artifact reduction, with ease in operation.
