  • Though not primarily a radiosurgeon, he introduced and developed rotational dynamic radiosurgery techniques and performed the first procedure in America using these methods for brain tumors, arteriovenous malformations, and functional disorders. (wikipedia.org)

  • Today, Leksell's technique is used as an effective treatment for many conditions such as arteriovenous malformations, pituitary tumors, acoustic neuromas, craniopharyngiomas, meningioma, metastatic and skull base tumors, and primary brain tumors. (wikipedia.org)
  • cancer
  • Onik treated the first liver patients with cryosurgery in 1986 and the first patient with ultrasound guided prostate cryosurgery in 1990, and has developed techniques and instrumentation that have been integral to the minimally invasive treatment of cancer. (wikipedia.org)
  • Dr Onik developed the instrumentation and techniques that allowed for the cryosurgical ablation of prostate cancer, which is now an accepted alternative to radiation and radical prostatectomy and the preferred treatment for patients with prostate cancer who have failed radiation therapy.

  • The concepts and techniques he developed have had a major impact on the treatment of cancer patients throughout the world and his work has been recognized by awards given to him by major societies in both medicine and engineering. (wikipedia.org)
  • treatment
  • Today, both treatment techniques are complementary, as tumors that may be resistant to fractionated radiotherapy may respond well to radiosurgery, and tumors that are too large or too close to critical organs for safe radiosurgery may be suitable candidates for fractionated radiotherapy.
