Abstract

The invention discloses a method for reusing operation parameters of high-intensity focused ultrasound equipment. The method comprises the following steps: before a patient is moved, scanning the patient with magnetic resonance imaging equipment to obtain an image before moving; after the patient is moved, positioning a sickbed which bears the patient and scanning the patient with the magnetic resonance imaging equipment again according to scanning parameters used by the image before moving to obtain an image after moving; judging whether a position difference before and after the patient is moved is acceptable according to the image before moving and the image after moving; if the position difference is acceptable to the high-intensity focused ultrasound equipment, proceeding the operation by adopting the operation parameters before the patient is moved; and otherwise, performing the step of positioning the sickbed and the subsequent steps again. By adopting the method, after the patient is moved, the high-intensity focused ultrasound equipment can still adopt the operation parameters before the patient is moved.

Description

technical field

[0001] The invention relates to the technical field of high-intensity focused ultrasound (HIFU) monitored by magnetic resonance imaging (MRI), in particular to a method for making operating parameters of high-intensity focused ultrasound equipment reusable. Background technique

[0002] In the high-intensity focused ultrasound (MRI guided HIFU) equipment monitored by magnetic resonance imaging, the magnetic resonance imaging equipment usually scans to obtain images of relevant parts of the patient, and then the high-intensity focused ultrasound equipment uses the images scanned by the magnetic resonance imaging equipment as Referring to the images, operations are performed to treat patients with ultrasonic waves.

[0003] In general, high-intensity focused ultrasound equipment is operated for a longer period of time, often hours. It is difficult to keep the patient still for such a long time. After the patient moves, because the position of the patient chan...
