Abstract

This paper aimed to explore the application values of computed tomography (CT) imaging in the treatment of patients with severe traumatic brain injury (STBI), to provide help in the treatment of STBI. In this study, 86 patients with STBI were selected as the research objects and examined by CT based on a self-adaptive particle swarm algorithm (APSO). Besides, patients were treated with hyperbaric oxygen, high-dose hormone shock, and naloxone hydrochloride. The results showed that there was a locally low-density brain contusion and laceration injury area, spot-like high-density hemorrhage, and subarachnoid hemorrhage in the images of CT examination. The ventricles of diffuse brain injury were compressed and reduced, and the white matter indicated that the ventricles and cisterns became smaller. Asymmetric hemorrhage and subarachnoid hemorrhage were scattered at the white matter junction. In short, subarachnoid hemorrhage, spot-like high-density hemorrhage at the injury site, and diminished ventricles were typical CT imaging manifestations of STBI. Naloxone hydrochloride method could effectively alleviate the matrix metalloproteinase-9 (MMP-9) (23.47 ± 3.45) and S100 calcium-binding protein B (S100B) (0.16 ± 0.06) of patients, which had reliable guiding significance for the later CT examination clinically.

Highlights

Severe traumatic brain injury (STBI) refers to a patient who has suffered severe craniocerebral trauma, immediately showing a deep coma after the injury, and the coma time is generally greater than 12 hours [1]
According to the simulation experiment in the same environment, the basic PSO (BPSO), quantum PSO (QPSO), and APSO were tested by Sphere, Shaffer, Griewank, and Rastrigin functions. e results of different algorithm test functions to optimize the time showed that the search and positioning time of APSO was faster than that of BPSO and QPSO (Figure 1)
Combined with the above results, it indicated that the four test functions were adopted to detect the three algorithms, and APSO had advantages over BPSO and QPSO

Summary

Introduction

Severe traumatic brain injury (STBI) refers to a patient who has suffered severe craniocerebral trauma, immediately showing a deep coma after the injury (often moderate or deep coma), and the coma time is generally greater than 12 hours [1]. Computed tomography (CT) applies the X-rays, c-rays, and ultrasound to scan a certain part of the human body together with a highly sensitive detector. It is featured with fast scanning time and clear scanned images [3]. X-rays are employed to scan the craniocerebral parts of the human body. En, the photoelectric signals are converted into electrical signals that are transformed into numbers through the processing of digitizers. X-rays are employed to scan the craniocerebral parts of the human body. e detector receives the X-rays at this level and converts them into visible light. en, the photoelectric signals are converted into electrical signals that are transformed into numbers through the processing of digitizers. e numbers are input into the computer for data processing. e image formation process is equivalent to dividing the selected layer into several rectangular parallelepipeds with the same volume, called voxels [4]. e X-ray absorption coefficient of each voxel is arranged into a digital matrix and stored on the optical disc
