Segmentation by type classifies Transcranial Doppler Ultrasound Devices into three core architectures: handheld units, cart‑based platforms, and fixed‑installation systems. Handheld devices, comprising approximately 40 % of unit shipments, prioritize portability and battery operation, enabling point‑of‑care assessments in emergency departments and ambulatory clinics; their lower capital outlay expands adoption among smaller facilities. Cart‑based systems, responsible for roughly 45 % of revenue, integrate advanced signal‑processing modules, multi‑frequency transducers, and duplex imaging capabilities, supporting comprehensive neurovascular examinations in tertiary hospitals. Fixed‑installation solutions, representing the remaining 15 %, are engineered for continuous monitoring in neuro‑intensive care units, featuring redundant power supplies and networked data archiving; their higher upfront cost is offset by long‑term service contracts. Within each architecture, sub‑types such as continuous‑wave, pulsed‑wave, and duplex Doppler further differentiate functionality, influencing pricing tiers and market penetration across clinical settings. This typology clarifies how product design choices translate into distinct revenue streams within the overall market.
