Treatment plans using linac-based intensity-modulated radiation therapy and helical TomoTherapy

This study evaluated whether helical tomotherapy (TOMO) planning could achieve better isodose distribution for the maxillary sinus while concomitantly sparing the adjacent _critical normal organs than linac-based step-and-shoot IMRT (s-IMRT) planning.

A case report on the effect of fan beam thickness in helical tomotherapy of nasopharyngeal carcinoma

The aim of this case study is to evaluate the dosimetric influence of changing the fan beam thickness (FBT) in the treatment of a nasopharyngeal carcinoma (NPC) patient.

Ocular Lymphoma

CyberKnife radiosurgery was recommended to provide rapid regression and to maximize the opportunity for local control within the right orbit while minimizing any damage to the optic nerve and other critical structures.

Posterior Fossa Renal Cell Metastasis

Due to the tumor location, stereotactic radiosurgery (SRS) was indicated in favor of operative surgery. The patient proactively inquired six months prior regarding the possibility of CyberKnife® treatment should she develop recurrent disease in the lung or brain. SRS is a well recognized technique for the treatment of cerebellar renal cell carcinoma metastases.

Optic Apparatus Meningioma

Treatment with CyberKnife radiosurgery utilizing a hypofractionated treatment regimen was indicated for maximum local control and to minimize injury to the optic apparatus.
