Our Use of Technology


MaineGeneral uses many different technologies to treat our patients with cancer.

Your radiation oncologist will discuss with you and your family which technology provides the best treatment options for your type of cancer.

You'll have peace of mind knowing we offer the most advanced technology available, including:

CT Simulator

  • The CT simulator is uniquely designed to help develop your treatment plan.
  • Our highly trained staff uses this system to properly position patients for treatment planning.

Eclipse Treatment Planning System

  • Eclipse is a comprehensive system for planning all types of radiation treatment.
  • It helps the oncology team to efficiently create, select and verify the best treatment plans and ensures proper dosages for each patient.

High-Dose-Rate (HDR) brachytherapy

  • HDR brachytherapy treats cancer by precisely placing radioactive implants in tumors.
  • It delivers high-intensity radiation directly into tumors through fine needles or catheters.
  • The total dose is delivered in a series of treatment sessions.
  • HDR may be offered as a single technology or in addition to other forms of therapy.

IGRT (Image Guided Radiation Therapy) and OBI (On-Board Imager)

  • IGRT is the most advanced form of radiation therapy available.
  • Tumors can shift and move slightly between treatments because of normal processes such as breathing.
  • The On-Board Imager (OBI) provides improved tumor targeting with high-resolution, low-dose digital imaging.
  • The tumor's target can be "imaged" and minor adjustments can be made to the patient's position before treatment is delivered.
  • This accuracy results in higher radiation doses to the tumor and increases the likelihood of controlling the cancer.

IMRT (Intensity Modulated Radiation Therapy)

  • IMRT is a state-of-the-art cancer treatment that allows precise delivery of high-dose radiation directly to tumors while leaving the healthy surrounding tissue unaffected.
  • Pencil-thin beams of varied (modulated) intensities are delivered in timed sequences to precisely defined areas of a tumor.
  • Manipulating the radiation beam this way allows the intensity of each beam to be adjusted in proportion to tumor thickness.
  • IMRT uniformly distributes radiation to the entire tumor.
  • RapidArc soffware dramatically reduces IMRT treatment times.

Linear accelerators

  • Linear accelerators are highly sophisticated machines that deliver precise, megavoltage radiation therapy treatment directly to cancerous tumors.

Portal imaging

  • Electronic images of the treatment area are used to verify the treatment plan's accuracy before any dose is delivered to the patient.
  • These images make sure you are accurately positioned before the first treatment session and during treatments.
  • They show the exact shape, size and area covered by the treatment during the actual treatment.

Respiratory gating (RPM)

  • Respiratory gating allows radiation therapists and physicians to accurately monitor and compensate for tumor motion caused by breathing.
  • The system uses a sophisticated video monitor to define your breathing pattern.
  • We place a lightweight marker on you to track the motion.
  • After analyzing your breathing pattern, our staff creates a treatment plan to allow the radiation beam to operate only when the tumor is within the designated area.

3D ultrasound imaging

  • ClairtyTM (Elekta) is a three-dimensional ultrasound imaging technology that provides even greater accuracy of a patient's position before the treatment is delivered.
