Embodiment 1

[0021] Embodiment 1 Embodiment is preferred. Such as figure 1 , 2 Shown is the overall structure and decomposition structure of an infant body heart coil device used in a magnetic resonance imaging system of the present invention. The coil shell is divided into an elliptical arc-shaped upper half 30 and an inverted trapezoidal lower half 40, which are respectively connected to the inner coil of the coil. The upper half 10 and the lower half 20 of the shell are fixed by non-magnetic screws. The lower half of the coil casing is designed as an inverted trapezoid, which is convenient to place on the operating bed. The coil inner shell is divided into an elliptical arc-shaped upper half 10 and a lower half 20 to form an elliptical cavity for accommodating the baby's body, which fits well with the baby's body and improves its comfort. The joint part is provided with connecting lock components 11, 21, so that the baby body coil can be opened and closed arbitrarily, which is conven...

Embodiment 2

[0027] Embodiment 2 The number of channels of the coil circuit is 4, two on the upper and two on the lower, which are evenly pasted on the inner shell walls of the upper half and the lower half of the inner shell of the coil. Other implementation contents are the same as those in Embodiment 1, and will not be described in detail again.

Abstract

The invention discloses an infant body heart coil device for a magnetic resonance imaging system. According to the infant heart coil device, an external coil housing and an internal coil housing are respectively divided into an upper half part and a lower half part which can be randomly opened and closed, thus being convenient to operate; the upper half part and the lower part of the internal coil housing are elliptic arc shaped, which are combined to form an elliptic chamber body in an infant body; and a phased array coil circuit formed by a plurality of annular coils is uniformly adhered to the internal housing wall between the external coil housing and the internal coil housing. The infant body heart coil device disclosed by the invention is designed based on human engineering; with the adoption of the infant body heart coil device, the whole part of the infant body can be imaged clearly and uniformly, so that the signal to noise ratio of the coil and the comfortable level of an infant can be improved.

Description

technical field [0001] The invention relates to a radio frequency coil device used in a magnetic resonance imaging system for imaging the heart of an infant. Background technique [0002] Magnetic resonance imaging (MRI) uses a uniform strong magnetic field from the main magnetic system (called the MRI system main magnetic field-B 0 ) to polarize the spins of the hydrogen nuclei in the human body. The magnetically polarized nuclear spins generate a magnetic moment i in the human body. This magnetic moment points in the direction of the main magnetic field at steady state and yields no useful information if there is no excitation perturbation. By means of a uniform radio frequency (RF) magnetic field (called the excitation field or B 1 Magnetic field) excites the magnetic moments to generate nuclear magnetic resonance (NMR) signals, thereby obtaining magnetic resonance imaging (MRI) data. The radio frequency transmitting coil generates B in the image area to be detected ...
