Abstract

The present disclosure relates to systems and methods for attenuation correction. The system includes a coil module, which includes a flexible coil and a supporter. The supporter may be configured to hold the flexible coil. The flexible coil may be deformed to form a receiving space.

First claim

1 . A system comprising a coil module, the coil module comprising:
a flexible coil; and an adjustable supporter configured to hold the flexible coil, wherein the flexible coil is deformed to form a receiving space, and a configuration of the flexible coil is based on a configuration of the adjustable supporter.

2 . The system of claim 1 , wherein the adjustable supporter is configured to reach different rigid states by adjusting a structure or shape of the adjustable supporter.

3 . The system of claim 1 , wherein the coil module further comprises a marker configured to indicate a position of the coil module.

4 . The system of claim 1 , wherein the flexible coil comprises a first fixture, the adjustable supporter comprises a second fixture, and the flexible coil and the adjustable supporter connect to each other through an assembly of the first fixture and the second fixture.

5 - 6 . (canceled)

7 . The system of claim 4 , wherein the assembly type of the first fixture and the second fixture comprises at least one of buttoning, tying, sticking, or clasping.

8 . The system of claim 4 , wherein the first fixture comprises a side coil box and a middle coil box.

9 . The system of claim 4 , wherein the second fixture comprises a side fixation box and a middle fixation box.

10 . The system of claim 9 , wherein the side coil box is configured to fit into the side fixation box.

11 - 20 . (canceled)

21 . The system of claim 1 , wherein the system includes a magnetic resonance imaging (MRI) system or a positron emission tomography-magnetic resonance imaging (PET-MRI) system.

22 . The system of claim 21 , wherein the system includes a scanner and a bed.

23 . The system of claim 22 , wherein the system further includes a rail configured to guide movement of the coil module.

24 . The system of claim 3 , wherein the marker is further configured to indicate a position of a target body.

25 . The system of claim 3 , wherein the marker is attached on the flexible coil and/or the adjustable supporter.

26 . The system of claim 1 , wherein the supporter is made of a plastic material or a composite material.

27 . The system of claim 1 , wherein the flexible coil is connected to the adjustable supporter through at least one of: gluing, welding, riveting, pressing, or casting.

28 . The system of claim 1 , wherein the configuration of the adjustable supporter is adjusted continually according to the configuration of the target body.

29 . The system of claim 1 , wherein the configuration of the adjustable supporter is adjusted based on a plurality of predetermined configurations.

30 . The system of claim 9 , wherein the side fixation box and the middle fixation box are connected by a collapsible component.

31 . The system of claim 30 , wherein the configuration of the supporter is adjusted by expanding or shortening the collapsible component.

32 . A coil module, comprising:
a flexible coil; and a supporter connected with the flexible coil, wherein the supporter is configured to hold the flexible coil, wherein: a configuration of the flexible coil is adjusted based on a configuration of a target body by adjusting a configuration of the supporter.
