Embodiment 1

[0024] As shown in Figure 1-2, a HIFU tumor ablation system includes an open MRI system, the magnetic materials 5 and 6 of the open MRI system are arranged perpendicular to the ground, and the direction of the main constant magnetic field of the MRI system is parallel to the ground , also includes an upper-mounted HIFU treatment device 1 arranged on the upper part between the magnetic materials of the open MRI system and a lower-mounted HIFU treatment device 2 arranged on the lower part between the magnetic materials of the open MRI system, and also includes a Patient support device 3 for carrying a patient.

[0025] The magnetic materials 5 and 6 are vertically arranged on a base 4 placed horizontally on the ground. The MRI magnetic resonance imaging system adopts an open structure with its opening facing upwards. The HIFU high-intensity focused ultrasound system is placed at the opening of the MRI magnetic resonance imaging system.

[0026] Wherein, the top-mounted HIFU trea...

Embodiment 2

[0032] Embodiment 2 differs from Embodiment 1 in that: the HIFU treatment device is an upper-mounted HIFU treatment device located above the patient carrying device, not shown in the figure, and the other structures of Embodiment 2 are the same as those of Embodiment 1, and are not mentioned here. Do repeat.

Embodiment 3

[0034] Embodiment 3 differs from Embodiment 1 in that: the HIFU treatment device is a lower-mounted HIFU treatment device located below the patient carrying device, which is not shown in the figure. The other structures of Embodiment 3 are the same as those of Embodiment 1, and are not mentioned here. Do repeat.

Abstract

The invention relates to a HIFU cancer fusion system, which comprises at least one HIFU therapeutic-equipment and one open MRI system, wherein the magnetic material of MRI system is vertical to the ground; said therapeutic-equipment is between the magnetic materials. The invention combines MRI technique and HIFU technique, to mount HIFU therapeutic-equipment between magnetic materials easily. The invention has high safety, reliability and low cost.

Description

technical field [0001] The invention relates to the field of tumor treatment, in particular to a HIFU tumor ablation system. Background technique [0002] MRI (Magnetic Resonance Imaging) system is an imaging technique that reconstructs images by collecting signals generated by magnetic resonance phenomena. The atomic nuclei (including cardinal protons or neutrons, generally referring to hydrogen protons) in human tissue are magnetized in a strong magnetic field. After the gradient field gives spatial orientation, radio frequency pulses excite hydrogen protons with a specific precession frequency. The energy released during the hesitation process is the magnetic resonance signal. The computer collects the magnetic resonance signals, converts them into black and white grayscale according to the signal intensity, forms two-dimensional or three-dimensional forms according to the position, and finally forms a magnetic resonance image (MRI). It has the advantages of no radiatio...
