Accuracy of CyberKnife spinal radiosurgery using skeletal structure tracking

The Xsight spine tracking system is practically important because it is accurate and eliminates the use of implanted fiducials. Experience has shown this technology to be robust under a wide range of clinical circumstances.

A motion phantom study on helical TomoTherapy: the dosimetric impacts of delivery technique and motion

Helical tomotherapy (HT) can potentially be used for lung cancer treatment including stereotactic radiosurgery because of its advanced image guidance and its ability to deliver highly conformal dose distributions.

A Monte-Carlo derived dual-source model for helical tomotherapy treatment planning

Full Monte Carlo radiation transport simulations of accelerator heads are impractical for routine treatment planning because of the excessive computational burden and memory requirements. To improve the accuracy and efficiency of treatment plans for helical tomotherapy, we have developed a dual-source model to characterize the radiation emitted from the head of a commercial helical tomotherapy accelerator.

A fast, accurate, and automatic 2D-3D image registration for image-guided cranial radiosurgery

The authors developed a fast and accurate two-dimensional (2D)-three-dimensional (3D) image registration method to perform precise initial patient setup and frequent detection and correction for patient movement during image-guided cranial radiosurgery treatment.

A dosimetric comparison between two intensity-modulated radiotherapy techniques

This manuscript describes a direct comparison between radiation treatment plans in terms of dosimetric outcomes created by two different IMRT systems: TomoTherapy HiArt and dynamic linac intensity-modulated radiotherapy (dIMRT).

Dosimetric analysis comparing treatment of low-risk prostate cancer

TomoTherapy offers a more favorable dose distribution to the bladder and rectum, as well as improved target homogeneity in comparison with IMRT.

Assessment of patient setup using daily MVCT imaging from more than 3,800 helical TomoTherapy treatments

To assess patient setup corrections based on daily megavoltage CT (MVCT) imaging for four anatomic treatment sites treated on tomotherapy.

Treatment plans using IMRT with helical TomoTherapy and 3D conformal radiotherapy

The purpose of this study was to compare radiation treatment plans (RTPs) that used intensity-modulated radiation therapy (IMRT) with helical tomotherapy (HT) or three-dimensional conformal radiation therapy (3D-CRT) for nasal natural killer/T-cell lymphoma (NNKTL).

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.
