Embodiment 1
[0045] refer to figure 1 with Figure 2A , The embodiment of the present invention includes an operation control system 1, a three-dimensional planning system 2, an energy controller 3, a B-ultrasound system 4, a multi-dimensional motion system 5, a water treatment system 6, a treatment bed 7, a positioning device 8 and the like.
[0046] In Embodiment 1 of the present invention, CT images with higher resolution are used as diagnostic images. There are many types of existing CT machines, and GE, Philips, Siemens, Toshiba and other commercially available products can be selected, such as LightSpeed16 of Ge. Related information can be found at the following website: http: / / www.gehealththeare.com / cnzh / rad / ct / produets / light_series / index.html
[0047] Under the CT image, align and fuse the B-ultrasound image of the patient (Esaote’s B-ultrasound machine DU4 (see http: / / www.esaote.com.cn / product.asp) can be used to guide the operation The patient can be treated, or a three-dimens...
Embodiment 2
[0051] Embodiment 2 of the present invention, with reference to figure 1 with Figure 2B , through the alignment and fusion of the high-resolution MRI images used for diagnosis and the B-ultrasound scan images under the treatment system, guide the operator to perform treatment, or make a three-dimensional plan based on the aligned and fused images, and then implement them in the operation Automated treatment under patient monitoring.
[0052] The MRI image can be obtained using commercially available equipment, such as GE's Signa MR / i1.0 / 1.5T (see website http: / / www .gehealthcare.com / czh / rad / mri / products / mri / mri.html).
Embodiment 3
[0054] Embodiment 2 of the present invention, with reference to figure 1 with Figure 2C Through the alignment and fusion of the MRI and CT image fusion images with high resolution for diagnosis and the B-ultrasound scan images under the treatment system, the operator is guided to perform treatment, or a three-dimensional plan is made based on the aligned and fused images. Automatic therapy under operator monitoring is then implemented.
[0055] Before the CT and MRI images are fused, CT or MRI inspection scans are performed on the patient respectively, and the positioning device 8 is used for positioning and fixing during the inspection scans.
[0056] All the other steps are the same as in Example 1.
[0057] Common working steps of the embodiment of the present invention
[0058] Next, other processing steps of the present invention will be further described in detail.
[0059] Initial positioning and pre-positioning

Abstract
This invention relates to an ultrasonic curing system. It relates to focusing ultrasonic (HIFU) curing equipment guided by using image aiming and amalgamation method. The system includes central controlling device, ultrasonic energy apply equipment, movement and positioning device of the ultrasonic energy applies equipment, real time B chao image guiding device. This system also has posture fix device, and the B chao image can be registered to diagnosis image by using this fix device, and the B chao image can be coalesced with the diagnosis image on bases of the registry to guide the curing. Comparing to existing technique, this invention can solve the problem of high strength ultrasonic focusing curing effectively and with low cost. It provides a practical technique scheme to tumor curingproblem, and can be easily used in tumor clinical treatment.
Description
technical field [0001] The invention relates to an ultrasonic treatment system, in particular to a focused ultrasonic (HIFU) treatment device guided by image alignment and fusion methods. Background technique [0002] In recent years, the use of ultrasound therapy has become more and more extensive. With the development of ultrasound therapy technology, special ultrasound therapy, especially high-intensity focused ultrasound (HIFU), can be used to effectively treat many diseases with damaging doses, especially for the treatment of tumors. , which causes less damage to patients than traditional surgery or chemotherapy, and can achieve non-invasive treatment, so its clinical application is developing very rapidly. The indications include liver cancer, osteosarcoma, breast cancer, pancreatic cancer, kidney cancer, soft tissue tumors and pelvic tumors. [0003] Ultrasound therapy devices for treating tumors usually adopt a spherical focusing method, and ultrasonic waves emitted ...
