Embodiment Construction

[0037] The present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments.

[0038] A close-contact ultrasonic coupling adapter device for breast photoacoustic / thermoacoustic imaging detection, including a detection cup, a coupling liquid spray device, an air pressure adjustment device and a detection platform.

[0039] The detection cup includes a cup body and a cup tail. The cup body is a bowl-shaped structure corresponding to the shape of the breast, and is fixedly connected with the cup tail by screws. The tail end of the cup tail is provided with a threaded section for easy replacement. In order to better match different sizes of breasts to be tested, cups of different sizes should be designed, which at least include but are not limited to the following: 1. The opening diameter is 120mm and the length is 80mm; 2. The opening diameter is 100mm and the length is 60mm; 3. Opening diameter 80mm, length 40mm. When ...

Abstract

The invention relates to a close-contact ultrasonic coupling adaptive device for photoacoustic / thermoacoustic mammary gland imaging detection, and belongs to the technical field of photoacoustic / thermoacoustic imaging. The adaptive device comprises a detection cup, a coupling liquid spray device and an air pressure regulating device, wherein a to-be-detected breast is placed in the detection cup with the shape and the size corresponding to the breast; the coupling liquid spray device is connected with the detection cup, and can spray ultrasonic coupling liquid between the to-be-detected breast and the detection cup; and the air pressure regulating device is connected with the detection cup by an air guide tube, and inhales or deflates between the to-be-detected breast and the detection cup. The adaptive device has the advantages that the adaptive device is good in matching degree, safe, comfortable, easy to replace, and high in automation degree.

Description

technical field [0001] The invention relates to the technical field of photoacoustic / thermoacoustic imaging, in particular to a breast detection device, in particular to a close-contact ultrasonic coupling device and a detection method thereof. The invention can be assembled in a microwave thermoacoustic breast examination device and a photoacoustic imaging device. Background technique [0002] Pulsed laser / microwave excited photoacoustic / thermoacoustic imaging is a new type of non-destructive testing technology that has emerged in the past decade. It has attracted increasing attention due to its advantages of safety and non-destructive, high contrast, high resolution and high imaging depth. . When a substance is irradiated by pulsed laser / microwave, the absorption of laser / microwave energy by the substance can cause an instantaneous temperature rise. If the pulse width of the laser / microwave is narrow enough, the absorbed energy cannot undergo thermal diffusion within the ...
