Core Technical Parameters

Practical Application Cases

1. A municipal forensic authentication center accepted the entrustment of the local public security bureau to conduct forensic clinical identification of the injury degree of the victim in a vicious intentional injury case. The victim was beaten with a blunt instrument, resulting in multiple injuries all over the body. The clinical diagnosis was multiple left rib fractures, left orbital wall fracture, and comminuted nasal bone fracture. The core basis for case characterization and conviction and sentencing is the injury degree grade of the victim. The traditional manual film reading and manual measurement methods have the problems of large subjective error, difficult to fully present the subtle fracture characteristics, and non-reviewable measurement data, and the original film is difficult to be intuitively displayed in the court. The appraisers used this Forensic Clinical Image Digital Collection and Identification Management System to carry out 1400dpi high-precision digital scanning of the victim's multiple CT and X-ray films, which clearly presented multiple fine fracture lines, fracture displacement and soft tissue damage range. Through the professional measurement module of the system, they accurately measured the core indicators such as fracture displacement distance, wound length, orbital wall defect area, and nasal bone comminution degree, with a measurement accuracy of 0.01mm, providing objective and accurate quantitative data support for the injury degree assessment. At the same time, the system automatically embedded the measurement data and key fracture feature images into the standardized identification document template, and generated a forensic clinical identification opinion complying with judicial specifications with one click. The final issued identification opinion of serious injury grade II was fully accepted by the people's court, and became the core scientific evidence for the conviction and sentencing of the case. The digital images collected by the system were also clearly enlarged and displayed in the court trial, which intuitively presented the victim's injury and greatly enhanced the persuasiveness of the evidence.
    
2. A provincial forensic authentication center accepted the entrustment of the local intermediate people's court to conduct forensic identification of a major medical damage liability dispute case. In the case, the patient had internal fixation fracture and long-term non-union of bone after orthopedic surgery. The patient believed that there was a fault in the hospital's medical behavior, while the hospital claimed that the damage consequence was related to the patient's own activities. The two parties had major disputes on whether there was a fault in the medical behavior and the identification of causal relationship, and the trial of the case fell into stagnation. The appraisers used this system to carry out high-precision digital collection and archiving of all X-ray and CT films of the patient before operation and 12 re-examinations after operation. Through the functions of multi-image time sequence comparison and split-screen comparison of the system, they clearly restored the patient's bone morphology before and after operation, the implantation position of internal fixation, the bone healing process and the development process of internal fixation fracture. At the same time, through the accurate measurement module of the system, they quantitatively measured the key indicators such as the implantation angle deviation of internal fixation, fracture position, bone non-union gap, and screw loosening displacement, which provided complete and accurate imaging data support for judging whether there was a fault in the hospital's medical behavior, the causal relationship between the fault and the damage consequence, and the assessment of fault participation degree. The final issued forensic opinion was fully accepted by the people's court, providing a scientific basis for the fair trial and responsibility division of the case. The complete archived digital image data of the system also provided complete original evidence support for the subsequent expert review and judicial retrial of the case.
