Lower extremity coils and components thereof for magnetic resonance imaging

Abstract

The invention discloses a lower limb coil used for magnetic resonance imaging, which is assembled on magnetic resonance imaging equipment for carrying out magnetic resonance imaging on the lower limb of a patient. The lower limb coil used for magnetic resonance imaging comprises a shell, a first flexible board and a second flexible board assembled at two opposite sides of the shell and an adjusting component assembled on the shell and capable of moving up and down relatively to the shell in the vertical direction. The invention also provides a lower limb coil assembly used for magnetic resonance imaging, which comprises a sickbed and the above lower limb coil assembled on the sickbed. The height of the lower limb coil shell in the vertical direction relative to the sickbed can be adjusted via the adjusting component. According to the lower limb coil assembly used for magnetic resonance imaging disclosed by the invention, as the height of the shell in the vertical direction relative to the sickbed can be adjusted via the adjusting component assembled on the shell of the lower limb coil, heights of the first flexible board and the second flexible boards in the vertical direction relative to the sickbed are thus adjusted, different patients with lower limbs of different sizes can obtain well-qualified patient lower limb magnetic resonance images in the case of magnetic resonance imaging, and correct diagnosis by a doctor is facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of medical imaging, in particular to a lower limb coil for magnetic resonance imaging and components thereof. 【technical background】 [0002] A lower limb coil assembly for magnetic resonance imaging related to the present invention includes a hospital bed and a lower limb coil assembled on the hospital bed. The lower limb coil is used for magnetic resonance imaging of the patient's lower limbs, and includes a body with a receiving cavity, a cover locked on the body, and a first flexible plate and a second flexible plate interposed between the body and the cover. flex board. The first flexible board and the second flexible board are symmetrically arranged on opposite sides of the main body, and can be bent downward to cover the lower limbs of the patient when the lower limbs of the patient are located on both sides of the main body. The first flexible board and the second flexible board respectively surr...

Problems solved by technology

However, since the thickness of each patient's lower limbs is different, the lower limb coil is fixedly assembled on the hospital bed and cannot move relative to the hospital bed in the vertical direction, that is, the height of the lower limb coil relative to the hospital bed in the vertical direction cannot Adjustment, when the lower limb coil is used to perform magnetic resonance imaging on a patient with thin lower limbs, the image resolution of the obtained magnetic resonance image will be low due to the long distance between the second row of antennas and the third row of antennas from the patient's lower limbs 1. The signal-to-noise ratio of the image is low, which makes the doctor unable to make a correct diagnosis based on the image; when using the lower limb coil to perform magnetic resonance imaging on a patient with thick lower limbs, there will be a long distance between the first row of antennas and the patient's lower limbs The low image resolution and low signal-to-noise ratio of the obtained magnetic resonance images lead to problems that doctors cannot diagnose correctly
