Problems solved by technology

The disadvantages of the above-mentioned models are that each structure in the model is static and different, and cannot effectively simulate the movement changes of the heart in the actual human body. In the process of CT imaging research, the dose adjustment and parameter selection of the dynamic human body structure are insufficient.

Embodiment Construction

[0012] In order to better understand the technical solution of the present invention, the following will be further described in conjunction with the accompanying drawings and specific embodiments. The details of the embodiments are as follows:

[0013] like figure 1 , 2 1 is the right lung model; 2 is the left lung model; 3 is the heart model; 4 is the abdominal mass model; 5 is the cavity part of the body model; 6 is the cover part of the body model; 7 is the Skeleton model; 8 is a controllable two-way pump; 9 is a plastic hose. Among them, the skeleton is made of aluminum alloy, the heart is made of elastic rubber, and the other parts are made of organic plastic.

[0014] Various tissues and organs are composed of: right lung model 1, left lung model 2, heart model 3, abdominal mass model 4, body model cavity part 5, body model cover part 6, bone model 7, controllable two-way liquid pump 8. Hose 9. Liquid composition simulating blood. The phantom cavity part 5 can be co...

Abstract

The partial dynamic human body object model devices for CT imaging research include right lung model, left lung model, heart model, abdominal block model, body cavity model, body cover model, skeleton model, controllable bidirectional liquid pump, hoses and simulation blood. The present invention may be used in simulating practical human body in the dynamic target and heart CT imaging research.

Description

technical field [0001] The invention relates to a device in the technical field of medical equipment, in particular to a partially dynamic human body mock-up device for CT imaging. Background technique [0002] In radiotherapy equipment or CT equipment, it is often necessary to test and correct the radiation dose and system parameters, or to test a certain CT imaging technology. human body model. [0003] Through literature search to prior art, Gary H.Kramer etc. are in A Virtual TorsoPhantom and its Comparison to the LLNL and JAERI Torso Phantoms (a kind of virtual partial human body model and comparison with LLNL model and JAERI model), Radiat.Protect .Management (radiation protection management) 416:51-54, 1999 introduced the LLNL model, the JAERI model and the model they proposed. The shortcomings of the above-mentioned models are that each structure in the model is static and different, and cannot effectively simulate the movement changes of the heart in the actual hu...
