Embodiment Construction

[0041] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0042] Such as Figure 1-2 As shown, the quality inspection phantom suitable for digital subtraction angiography technology is composed of multiple cuboid modules, including ladder module 1, socket module 3, bone module 2, arterial blood vessel simulation module, resolution test module, lesion Simulation modules (heart coronary artery simulation module, carotid artery simulation module and renal artery simulation module), U-shaped block 4 .

[0043] The bottom of the whole phantom of the present invention is a square with a length of 20 cm.

[0044] Ladder module 1. A cuboid, the size is 20*20*7.5cm, it is composed of two parts, and the junction is in the shape of steps. Each part has three steps, and the two parts can be combined to form a large step. Each step is 2.5cm long.

[0045] The socket module 3 is 7.5cm high and 15cm wide. The bone module 2 is...

Abstract

The invention discloses a quality inspection body model suitable for digital subtraction angiography, and a detection method. The quality inspection body model comprises a U-shaped block, a socket module, a step module and a skeleton module which are sequentially stacked from bottom to top, wherein a jack is arranged in the socket module, a replaceable simulation module is arranged in the jack, and the replaceable simulation module comprises an artery blood vessel simulation module, a heart coronary artery simulation module, a carotid artery simulation module and a renal artery simulation module; and a resolution test module can be further placed in the socket module. The quality inspection body model further comprises a blank module and a mark module, wherein the blank module is used as a control group of the artery blood vessel simulation module and placed on the same plane with the artery blood vessel simulation module; and the mark module works cooperatively with the resolution test module. The quality inspection body model disclosed by the invention is close to a real case to a greater extent during detection because of being provided with the modules for simulating the carotid artery, renal artery and coronary artery diseases of a human body, thus more representative data is provided for quality inspection.

Description

technical field [0001] The invention relates to a quality detection phantom suitable for digital subtraction angiography technology and a detection method. Background technique [0002] Digital Subtraction Angiography (DSA) is a medical imaging device widely used in cardiovascular angiography examinations. It realizes blood vessel examinations by injecting iodine contrast agent into blood vessels and computerized image subtraction. The vascular imaging effect of DSA directly determines the detection ability of vascular diseases. At present, the detection of DSA vascular imaging ability can be realized by phantom test. However, the current DSA detection phantom can only perform imaging detection of basic simulated blood vessels, and cannot detect the imaging ability of specific, specific and 3-dimensional blood vessels. Contents of the invention [0003] The object of the present invention is to solve the above problems, provide a quality detection phantom and detection me...
