Gliomas are rare compared to cancers of the breast, lung, or colon, but few malignancies are more devastating. While no therapeutic breakthroughs have occurred, the treatment of glioma is improving. Surgical care is improving. Magnetic resonance imaging and intraoperative mapping studies are leading to safer, more complete resections. With scan-guided stereotactic biopsy, unresectable tumors ca...

New advances in radiation therapy for children allow increased conformability and reduced doses to non-target tissues. We report our experience in treating a 4-year-old child with craniospinal tomotherapy after surgery of the primary tumor, a supratentorial primitive neuroectodermal tumor. The tomotherapy plan was compared with conventional craniospinal irradiation, 3D conformal radiation thera...

We describe an automatic surface reconstruction technique from a set of planar data points organised in parallel sections. The reconstruction employs skeletal implicit surfaces. Two key points in this study are: Calculation of the 3D skeleton by establishing a correspondence between each pair of 2D Voronoi skeleton of two neighbouring sections, Use of a uniform field function necessitating the ...

Meningiomas are among the most common primary tumors of the central nervous system. We describe the case of an 82-year-old woman with meningioma, the epicenter of which was above the sella, causing her terrible headaches and severely compromised visual acuity. Although the patient was eligible for stereotactic radiosurgical treatment (SRS), she was treated with conventional 3D conformal radioth...

We show that every uniformly asymptotically affine circle endomorphism has a uniformly asymptotically conformal (UAC) extension to the complex plane. Then we use the UAC extension to construct the dual dynamical system, the dual annulus, and the dual circle expanding map.

Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...

PURPOSE To investigate the immediate and long term therapeutic effects of radiofrequency hyperthermia combined with conformal radiotherapy in patients with hepatocellular carcinoma (HCC). METHODS Data was collected from 80 patients with HCC. All of the patients had confirmed primary HCC according to their clinical symptoms, imaging examinations, biochemical examinations and pathology. Patient...
