Abstract
The article describes a system to control a unit moving to find the dependence of the photodetectors signals from the distance to the hematoma. It considers existing devices that operate in accordance with the principle of near infrared spectroscopy and reveals their limitations the illuminations of which are our key objective. The limitations of the designed unit are described and possible ways of upgrading the system are outlined.
Highlights
Identification of intracranial hematoma is extremely important in traumatic brain injury
Varying the position of ‘hematoma’ relative to the optical measuring unit we can determine how its movement change the data received from photodetectors and whether on the basis of these data to determine the size of the hematoma and its exact location
As a result of this work a stepper motor has been implemented to automate data reading from the optical part of the device
Summary
Identification of intracranial hematoma is extremely important in traumatic brain injury. According to the published experimental studies performed on models of intracranial hemorrhage, clinical trials have shown a high diagnostic sensitivity of the device This scanner allows you to detect the presence of hematomas with 91 % probability (in the case when hematoma is not deeper than 2.5 cm from the brain surface and is greater than 3.5 cm) [4, 5]. We design a model of the device that allows to carry out a laboratory research which will help to improve optical detection diagnosis of hematomas
