- High-Dose-Rate 192Ir Brachytherapy
- description
- 1. All patients underwent computed tomography (CT) 3-5 days before surgery. The collimation is 2.5 mm and CT Planning System. 2. Delineation of the gross tumor volume (GTV) and adjacent organs at risk (OARs); 3. Determination of the needle tract of the implanted insertion direction, distribution, and depth. Then calculation of the dose distribution of the target volume and OARs. 4. Depending on B-TPS data, we establish a digital model for the individual template. 5. Local anesthesia or intraspinal anesthesia was induced in all patients. The three-dimensional printing noncoplanar templates (3D-PNCT) was placed on the surface of the treatment area of the patient. The 3D-PNCT was aligned accurately with the outer-contour features. Through the guide hole of the 3D-PNCT, we inserted to pre-planned depths. 6. Delineation of the GTV and design planning . 7. Connect the source tube and 192Ir high dose rate interorganizational brinotherapy 8. At the end pressed to stop bleeding.
