The Types segmentation of the OFDI market distinguishes between endoscopic, intravascular, handheld, and integrated system architectures, each addressing distinct procedural contexts. Endoscopic OFDI systems, comprising roughly 25 % of the market, enable high‑resolution imaging within hollow organs such as the gastrointestinal tract, benefitting from flexible probe designs. Intravascular OFDI, with an estimated 35 % share, focuses on catheter‑based probes for coronary and peripheral vessels, emphasizing rapid pull‑back speeds and rotational scanning. Handheld OFDI devices, accounting for about 20 % of sales, target point‑of‑care diagnostics in ophthalmology and dermatology, offering ergonomic ergonomics and simplified user interfaces. Integrated OFDI platforms, representing the remaining 20 %, combine imaging with therapeutic delivery (e.g., laser ablation) or data analytics modules, facilitating comprehensive procedural workflows. This market taxonomy underscores the functional differentiation of OFDI hardware, illustrating how each type aligns with specific clinical pathways and contributes to the overall market size.
