Basic Edition
Overview
A 96-element curve-linear array collects more than 69,000 detection points in a single 360° rotation, resolving 150 µm in transverse planes at depths of 20–40 mm. Excitation covers 532 nm and 650–1320 nm, switchable to any wavelength in range every 50 ms.
Oxyhaemoglobin, deoxyhaemoglobin and melanin are visible without a contrast agent, so anatomy and vasculature are recorded alongside every molecular scan.
The chassis, holders, scan times and software are shared with the Premium edition. Basic has no fluorescence channel.
