Deformable registration of abdominal kilovoltage treatment planning CT and tomotherapy daily megavoltage CT for treatment adaptation

The authors evaluated the procedure on multiple image datasets from prostate cancer patients and gynecological cancer patients. Compared to rigid alignment, the proposed method improves volume matching by over 60% for the critical organs and reduces the prostate landmark registration errors by 50%.

CyberKnife stereotactic radiotherapy as monotherapy for low- to intermediate-stage prostate cancer: early experience, feasibility, and tolerance

This regimen of stereotactic CyberKnife monotherapy for low- to intermediate-risk prostate cancer with excellent dose coverage of the prostate was well tolerated. Data collection is ongoing for further assessment of toxicity and PSA response.

CyberKnife radiosurgery for prostate cancer

Recently, new data have emerged that show promising outcomes with minimal toxicity for CyberKnife SBRT of prostate cancer.

Comparison of quality of life after stereotactic body radiotherapy and surgery for early-stage prostate cancer

Overall, these results may have implications for patient and physician clinical decision making which are often influenced by QOL. These differences in sexual, urinary and bowel QOL should be losely considered in selecting the right treatment, especially in evaluating the value of non-invasive treatments, such as SBRT.

Acute toxicity after CyberKnife-delivered hypofractionated radiotherapy for treatment of prostate cancer

CyberKnife-delivered hypofractionated radiotherapy for the treatment of prostate cancer has an acceptable acute toxicity profile.

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.

Treatment Plan for Prostate Cancer

Highly-homogeneous dose. Excellent bladder and rectal sparing. Excellent small bowel sparing.

Robotic IMRT™ Treatment of Prostate Cancer

The ability to track and correct for prostate movements during treatment reduced uncertainty in target location, thereby allowing smaller treatment volumes than those possible using conventional IMRT systems.

Perineal Relapse of Prostate Carcinoma

The use of the CyberKnife System allows a clinician to perform accurate treatment because of its capability to track the tumor throughout treatment.

CyberKnife® Monotherapy for Low-Risk Prostate Cancer

The CyberKnife® System successfully reproduced an HDR-like dose distribution, delivering treatment in a minimally invasive fashion.
