[0008] one. software function

[0009] 1. image registration

[0010] The image of the patient can be registered and fused through the software, and the software provides two registration methods: automatic registration and manual registration. Automatic registration takes a period of time, and the system automatically registers according to the image data and automatically displays the registered and fused image in the specified view display area; manual registration is the way the user uses his own manual operation to manually move the image Complete the registration of the two views according to your own visual judgment, and then click the Finish button to end the manual registration operation.

Abstract

The invention relates to image analysis software for radionuclide pulmonary perfusion and ventilation tomography. The newly-developed computer software is utilized to implement three-dimensional registration for a pulmonary perfusion imaging tomography image and a pulmonary ventilation imaging tomography image, so that the pulmonary perfusion imaging tomography image and the pulmonary ventilation imaging tomography image reach good correspondence in a spatial position. Accordingly, a non-matching area and a matching area of the pulmonary perfusion imaging tomography image and the pulmonary ventilation imaging tomography image can be indentified and confirmed in range and degree. Therefore, a pulmonary embolism diseased region can be automatically identified, and the range and the volume of diseased lung tissue can be automatically identified. The quantitative analysis software for the pulmonary perfusion and ventilation tomography can be used for qualitative and quantitative diagnosis for pulmonary embolism and quantitative therapeutic effect evaluation for the pulmonary embolism.

Description

technical field [0001] The invention relates to a quantitative analysis software for radionuclide lung perfusion and ventilation tomography, which can be used for qualitative diagnosis of pulmonary thromboembolism and quantitative analysis of lesion range and degree. Background technique [0002] Pulmonary thromboembolism (referred to as pulmonary embolism) is a common pulmonary vascular disease that seriously endangers human health. Untreated pulmonary embolism has a mortality rate of up to 30%. After correct diagnosis and treatment, the mortality rate of pulmonary embolism can be reduced to 2.5%. Therefore, timely and accurate diagnosis is the key to the cure of pulmonary embolism. Lung perfusion and ventilation imaging is one of the most commonly used non-invasive imaging techniques for the diagnosis of pulmonary embolism and is widely used in clinic. In recent years, lung perfusion and ventilation imaging has gradually developed from planar imaging to tomographic imag...
