Abstract：Objective To investigate the accuracy and reliability of the localization of intracerebral hemorrhage (ICH) by smart phone based on easy-to-use augmented reality (AR) technique. Methods The clinical data of 42 patients with hypertensive ICH were analyzed retrospectively. The raw data of emergent head CT in digital imaging and communications in medicine data (DICOM) forum were loaded into open-source software 3D Slicer through Picture Archiving and Communicating System (PACS) of hospital. The hematomas and the scalps were reconstructed by the software before the screenshots with markers on the virtual scalp were transmitted to a smart phone. The easy-to-use augmented reality technique was realized through the camera of smart phone allowing a projection of the hematoma image on the patient's scalp. The profiles of the hematomas were depicted under the smart phone monitoring, and then four markers were fixed on the periphery of the hematomas. The patients underwent brain CT scan reexamination and the deviation o the markers from the actual hematoma boundaries were recorded and analyzed. Results The mean deviation of the marker from the actual hematoma boundaries was (3.1 ± 1.1) mm, ranging from 0.04 mm to 7.2 mm, on easy-to-use AR. There was no significant difference among the deviations of all the markers from all the boarders (P>0.05). Conclusion The low cost smart phone AR technique may provide relatively reliable and accurate localization of ICH.
