Problems solved by technology

However, after testing, it was found that although the signal-to-noise ratio of the image near the blood vessel was higher than that of the former, the uniformity and penetration were obviously not as good as figure 1 The 2×2 (elements) coil is high, and the clinical effect is generally not as good as the former

Embodiment

[0021] Embodiment: The carotid artery coil of the present invention includes two parts of the left and right coils, and each part of the coil has four coil elements. Coil structure of each part Figure 4 As shown, this coil has 4 coil elements (elements), of which three coil elements (three rectangles on the left, middle and right) are arranged in parallel, and another coil element spans the 3 coil elements arranged in parallel and forms a "8" ” unit of the word. The 4 coil units of each coil are in a 3+1 structure, that is, 3 parallel coil units (Loop) + 1 cross coil unit (saddle). 3 coil units (Loop) arranged in parallel are arranged from left to right (from the front to the back according to the direction of the human body), and 1 cross coil unit (saddle) is added, which spans 3 coil units arranged in parallel ( Loop). The 3 parallel coil units (Loop) in the coil have a good balance in signal-to-noise ratio and penetration. The arrangement of the other three parallel ...

Abstract

The invention discloses a carotid artery coil. The carotid artery coil comprises coil units, and is characterized in that at least three coil units in the coil units are arranged in parallel. Three parallel coil units in the coil have a good balance between the SNR (signal to noise ratio) and the penetrating power. A saddle-shaped (or 8-shaped) coil unit can be added in the coil so as to effectively increase the image SNR and uniformity of the coil without influencing other units. The SNR, uniformity and IPAT (information processing aptitude test) effect of the carotid artery coil are obviously superior to those of the existing two-channel coil in commerce.

Description

technical field [0001] The invention belongs to the field of magnetic resonance imaging, and in particular relates to a carotid artery coil. Background technique [0002] Stroke has historically been one of the leading causes of human death. New medical research shows that magnetic resonance imaging is currently the most effective medical tool for identifying potentially dangerous fatty plaques in the carotid arteries, which could help spot people at risk of stroke. Therefore, MRI magnetic resonance carotid artery imaging is a very attractive technology for the clinical diagnosis of carotid artery disease and the tracking of curative effect, and it will help to develop new drugs for reducing plaque. However, carotid artery imaging is also very difficult. In order to better distinguish the shape and composition of blood vessels, vessel walls and plaques, clinical images should not only have a sufficiently high signal-to-noise ratio, but also have high resolution at the submi...
