Abstract
A magnetic resonance imaging system for interventional MR imaging involving operations to insert a device such as a catheter into an object. According to the system, a tip position of the catheter is detected, data indicative of moved loci of the catheter are produced from data indicative of the detected tip position, and the produced movement locus data are displayed. In addition, even when an operator changes the progress direction of the device such as a puncture needle, an imaging cross section automatically tracks movements of the device. Appropriate preoperative plan means are also provided.
Claims23
A magnetic resonance imaging system for interventional MRI involving an operation to insert a device into an object, comprising:
- detection means for detecting a position of a tip of the device;
- and
- movement state display means for displaying a movement state of the tip of the device on the basis of data indicative of the position of the tip detected by the detection means.
A magnetic resonance imaging system for interventional MRI involving an operation to insert a device into an object, in which an image of a section of the object being obtained from an MR signal using an MR signal acquired through application of a magnetic field based on a given pulse sequence to the object, comprising:
- position detecting means for detecting positional information of the device;
- and
- control means for controlling imaging parameters included in the pulse sequence on the basis of the positional information detected by the position detecting means so that the section always contain the device.
A magnetic resonance imaging system for interventional MRI involving operations to insert a device into an object, in which an image of a section of the object being obtained from an MR signal based on an MR signal acquired through application of a magnetic field based on a given pulse sequence to the object, comprising:
- preoperative plan means for planning information in relation to the operations of the device based on the image prior to the operations;
- and
- output means for outputting the information in relation to the operations planned by the preoperative plan means in association with the object.
A method of preparing for interventional MRI involving operations of a device to be inserted into an object, the method comprising the steps of:
- acquiring an image of a section of the object through MR imaging with the object laid on a couch;
- planning, before the operations, information in relation to the operations of the device based on the image while the object is laid on the couch;
- and
- outputting the planned information in association with the object.
