Radiation Oncology is one of the most technologically integrated specialties in the medical field.  Your multidisciplinary team of dosimetrists, medical physicists, radiation oncologists, and radiation therapists use a complex weave of software and equipment to plan the best treatment for each patient.   


KU is known to be one of the region's best and highest-volume brachytherapy programs. Our program is one of very few centers to provide High Dose Rate (HDR) brachytherapy for a wide array of complex cancers (Prostate, breast, head & neck, GYN, and many more).  Read about our dedicated procedural suite and treatment areas in our brachytherapy section.  

Dedicated Procedural Suite  

A dedicated procedure room comprises our special procedure and surgical area where surgery and radiation therapy can be performed in a single procedure.  A special treatment room connected to the procedure rooms contains a Nucletron, high-dose, rate machine capable of delivering radiation all within the same outpatient setting. 

 CT-Drive Virtual Simulation  

All our KU sites have a CT Simulator dedicated to simulating radiation treatments for each individual patient. These simulations are used to test various treatment fields and devices used to immobilize the patient during therapy.  Data from the CT Simulator ensures that patients get the appropriate setup, planning, and dose of radiation before their treatment starts.

Linear Accelerators  

A Linear Accelerator (often shortened to linac) is a sophisticated machine specifically designed to generate high-energy X-rays and electrons for the treatment of patients. Your radiation oncologist plans and calculates the best treatment method and delivery for everyone. At KU, you will be treated with state of the art Linear Accelerators capable of delivering sophisticated therapies including Intensity-Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT), Stereotactic Radiosurgery (SRS), Stereotactic Radiotherapy, Stereotactic Spine Radiotherapy, and Stereotactic Body Radio Therapy (SBRT).  A few of our machines are highlighted below:  

  • Novalis Tx Technology
  • TrueBeam System
  • Trilogy

Stereotactic Radiosurgery  

Stereotactic Radiosurgery involves a single, high-dose application of radiation to the tumor instead of the many smaller doses given in standard treatment. Several radiation beams are precisely aimed to converge upon a small tumor. The patient lies on a couch that rotates 180 degrees for maximum targeting without harming surrounding tissues. This technique is used to treat brain tumors and other intracranial cancers.  

Stereotactic Radiotherapy  

This is a new term often not recognized; however, it represents the Stereotactic methodology with Intensity-Modulated Radiation Therapy (IMRT) delivery.  Patients receiving such treatments include those with tumors in the central nervous system and head and neck regions.  

Stereotactic Spine Radiosurgery  

Stereotactic guided radiation is combined with CT guidance for the highest possible dose to spinal tumors while minimizing harmful side effects.    

Stereotactic Body Radiotherapy (SBRT)  

SBRT combines elements of three-dimensional conformal radiotherapy (3D-CRT) / Intensity-Modulated Radiation Therapy (IMRT) which links CT scans of the tumor site with treatment-planning software to determine optimum photon radiation beam direction and intensity and Image-Guided Radiation Therapy (IGRT) techniques that cope with tumor motion and anatomy changes during radiotherapy.  

SBRT allows the delivery of an ablative dose of radiation to the target in significantly shortened treatment time. Individual treatments, called "fractions", have been reduced from 35 to fewer than 5 in this approach while minimizing damage to normal tissues in the tumor region. This approach has been used in patients with early stage or isolated, recurrent/metastatic cancer in the lung, liver, and other sites.  At KU, we are designing cutting-edge clinical trials using the SBRT approach in numerous disease sites to make treatment more effective and convenient for patients.
