How AI is Reshaping the Future of the Japan Computed Tomography (CT) Market?
Artificial intelligence is also transforming radiology in Japan by improving the accuracy and efficiency of computed tomography scans. AI-based image reconstruction algorithms have enabled scanning machines to produce higher quality imaging with a greatly reduced dose of radiation being used in the procedure. AI models trained with deep learning provide the ability to discover subtle abnormalities, such as early signs of cancer and fine vascular abnormalities that a radiologist may overlook, while minimizing false positive classification. The AI model was trained using tens of thousands of scans of the Japanese population, accounting for anatomical variability and disease spectrum.
The use of AI is changing the workflow of radiologists and standardizing expert-level evaluation throughout the Japanese healthcare system. Automated image evaluation can prioritize, flag, and provide a first pass of a formal interpretation based on radiologist review, greatly improving the turnaround time of cases. Natural language generation of reports gives radiologists time to focus on more complex cases and the human interpretation of the scans. Artificial intelligence quality control systems monitor scan parameters to enable a standard in imaging and improve quality among facilities and operators. This has proven especially useful in addressing Japan's shortage of healthcare professionals and providing comparable diagnostic services to rural and remote medical facilities.
Next-generation CT imaging in Japan will also depend on the use of AI and predictive modeling in the field of personalized medicine, where machine learning will be tasked with predicting radiation doses and scan parameters for the best possible image quality. Integrating AI systems with EHRs will permit correlating CT results with patient characteristics, history, and genetic data; improving diagnosis and allowing personalized treatment for the individual patient. In Japan, the anticipated increase in demand for medical services and the related increase in cost due to an aging population have led to AI CT systems being seen as essential to high-quality CT with limited resources.
Japan Computed Tomography (CT) Market Trends & Drivers
The prevalence of chronic disease in Japan, which typically requires advanced imaging techniques to diagnose and treat, has resulted in a strong growth of the CT market. Cancer and cardiovascular disease are the most popular health problems in the country. Though increasing in Japan, the overall prevalence of accidents and trauma is another factor that drives the need for CT, as its rapid and accurate diagnostic capabilities are particularly useful in medical emergencies where time is of the essence. This growing geriatric population is another reason CT use is expected to grow. As a result of this trajectory in health expenditure and investment in medical imaging infrastructure, CT technology is widely available across the country.
Technological advancement is another key factor contributing to future market growth. High-resolution CT machines with better imaging capabilities are being developed to identify smaller abnormalities with greater accuracy. The rise of portable CT scanners is anticipated to gain popularity in the future due to its effective and cost-efficient production, improved treatment procedures, and reduced time for taking patients from one place to another. Portable systems are especially useful in the Emergency Department, or ICU, where moving the patient from the bed can be medically risky. In addition, the surge in CT applications for minimally intrusive surgery and robotics has propelled market growth. Pre-operative assessment of CT scan is used to assess for risk and select the most appropriate procedure to improve patient outcomes.
