The global photon-counting CT market size is likely to be valued at US$0.5 billion in 2026, and is expected to reach US$3.1 billion by 2033, growing at a CAGR of 30.0% during the forecast period from 2026 to 2033, driven by superior image quality, lower radiation dose, and increasing adoption in advanced diagnostic imaging. Increasing demand for high-resolution, low-dose CT imaging in cardiology, oncology, and neurology remains a major driver of photon-counting CT market growth.
