Problems solved by technology

The Tada formula method is more accurate for the measurement of hematoma with small bleeding volume and ellipsoidal shape, but it is not accurate for the measurement of large bleeding volume, irregular shape, intraventricular hemorrhage, and subdural hematoma; although the CT quantitative method can accurately calculate the hematoma area, However, CT machine measurement is not only time-consuming, but also takes up the CT machine and costs a lot of money. Therefore, CT is rarely used to measure the volume of intracranial hematoma.

Embodiment 1

[0021] Such as Figure 1 to Figure 3 Shown: An application system for subdural hematoma volume calculation, including information measurement input module, hematoma volume calculation module and hematoma volume output module, information measurement input module is used to complete the measurement of related parameters, and Input to the hematoma volume calculation module, the hematoma volume calculation module is used to complete the hematoma volume calculation, and the hematoma volume output module outputs the hematoma volume. The described hematoma volume calculation module can be composed of computer and VB software. Its control method is based on the polygon formula method to write a VB program. By drawing points in the CT image, each layer of CT is approximated as a polygon, and then uses the written program to calculate each layer. The area of ​​the CT image of the layer is calculated according to the area multiplied by the thickness and the ratio of the CT image, and th...

Abstract

In order to overcome the defects in the prior art, the invention aims at providing an application system for subdural hematoma volume calculation with the advantages that the intracranial hematoma volume can be accurately measured, the time consumption is low, and the money consumption is low. The application system has the technical scheme that the application system for subdural hematoma volume calculation comprises an information measurement input module, a hematoma volume calculation module and a hematoma volume output module. A control method is characterized in that a VB (visual basic) program is compiled on the basis of a polygon formula, points are drawn on a CT (computed tomography) image, each layer of CT approximates to a polygon, then, the area of each layer of CT image is calculated by utilizing the compiled program, and the volume of each layer is further calculated through multiplying the area by the thickness and the CT image proportion,.

Description

technical field [0001] The invention belongs to the field of applied medical technology, in particular to an application system for calculating the volume of subdural hematoma. Background technique [0002] Judging the size of intracranial hematoma and the amount of cerebral hemorrhage are important indications for surgery and objective indicators for disease progression and curative effect evaluation. Therefore, it is of great significance to accurately measure the volume of intracranial hematoma. At present, methods for measuring hematoma volume with CT images include CT quantitative method and Tada formula method. The Tada formula method is more accurate for the measurement of hematoma with small bleeding volume and ellipsoidal shape, but it is not accurate for the measurement of large bleeding volume, irregular shape, intraventricular hemorrhage, and subdural hematoma; although the CT quantitative method can accurately calculate the hematoma area, However, CT machine me...
