Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray CT apparatuses are not optimized for scanning corpses, requiring manual adjustment of scanning parameters for each corpse, which is inefficient and can lead to inaccurate diagnoses, especially in cases of mass disasters where resources are scarce.
Innovation Solution
An X-ray CT apparatus with pre-defined scanning modes for different causes of death, including charred, drowned, and injured bodies, allowing for efficient scanning by selecting appropriate scanning conditions and reconstructing images based on these modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional X-ray CT apparatus is used for scanning corpses without specialized protocols, then the apparatus can perform basic scanning functions, but scanning efficiency is low and requires manual parameter adjustment for each corpse
Solution Approach 1:
The patent pre-defines multiple death mode protocols (charred body, drowned body, injured body, etc.) with optimized scanning parameters before actual scanning. When a corpse is scanned, the operator only needs to select the appropriate death mode, and the system automatically applies the pre-configured parameters, eliminating manual parameter adjustment and大幅提高 scanning efficiency.
Solution Approach 2:
The patent creates different scanning parameter sets tailored to specific death modes. Each death mode protocol contains optimized parameters (kVp, mA, scan time, reconstruction algorithms) specifically suited for that type of corpse condition. This allows the system to automatically adapt parameters based on the selected death mode, improving both efficiency and diagnostic accuracy.
2Measurement precision
If manual anatomy is performed for all corpses to determine cause of death, then accurate diagnosis can be achieved, but it requires a long time and greatly burdens doctors
Solution Approach 1:
The system performs preliminary imaging assessment through automated scanning with death mode protocols before anatomy. The high-resolution CT images provide detailed visualization of organ damage, bone fractures, and other pathological conditions, allowing doctors to pre-screen corpses and identify those requiring detailed anatomical examination, thereby reducing overall anatomy time while maintaining diagnostic accuracy.
Solution Approach 2:
The patent creates detailed 3D digital copies of corpses through high-resolution CT scanning and image reconstruction. These digital models allow doctors to virtually examine internal structures, organ damage, and injuries without immediate physical dissection. This virtual autopsy capability provides accurate diagnostic information while significantly reducing the time and effort required for traditional anatomy.
3Reliability
If scanning parameters are manually adjusted for each corpse, then scanning conditions can be optimized, but the process cannot scan a number of corpses efficiently
Solution Approach 1:
The patent creates universal death mode protocols that can be applied to multiple corpses of the same death mode type. Each protocol is designed to handle various conditions within that category (e.g., different severities of burns for charred bodies), allowing the system to efficiently process multiple corpses by simply selecting the appropriate protocol without requiring individual parameter optimization for each case.
Solution Approach 2:
The system pre-configures optimized scanning parameters for each death mode protocol, including kVp, mA, scan range, rotation speed, and reconstruction settings. This preliminary optimization ensures that when multiple corpses are scanned, the system can immediately apply proven parameters without time-consuming adjustments, enabling efficient mass corpse scanning while maintaining reliable image quality.

AI summary
To provide an X-ray CT apparatus and a scanning method that can scan a corpse efficiently, a death mode is selected and input to the CPU of an image processing device by performing a mouse-click or touch operation on any of buttons on a death mode selection window. The CPU obtains scanning conditions from the storage unit according to the input death mode. In a charred body mode, scanning conditions are defined in advance to perform high-resolution scanning for the pelvis portion and standard scanning for the other entire body for sex estimation. The sex estimation process estimates the corpse's sex based on the pelvis portion shape and outputs the results. In a drowned body mode, scanning conditions are defined in advance to perform high-resolution scanning for the lung field and standard scanning for the other entire body to measure a water amount in the lung.
