Our Leading-Edge Technology

 

Advanced CT Simulation

Every patient undergoes CT simulation. The simulator demonstrates precise 3-D reconstruction of both tumorous and normal tissue. Sophisticated technology combines CT scanning and treatment planning software to help our clinicians create an optimal radiation therapy plan. For the patient, therapy planning is much faster with CT simulation as opposed to traditional fluoroscopy-based units.

3-D Conformal Radiation Therapy

3-D CRT offers a more precise analysis of the area in and around the target, resulting in radiation dose that closely conforms to the region at risk while sparing adjacent normal tissue. 3-D CRT is used for the majority of our patients. Transperineal Interstitial Brachytherapy Also known as “seed therapy,” this treatment alternative for prostate cancer involves the implantation of tiny radioactive seeds directly into the prostate gland. With transrectal ultrasound and computer calculation and display capabilities, our clinicians can accurately place the seeds to deliver a high dose of radiation to the prostate, while sparing neighboring organs like the bladder and rectum.

Intensity Modulated Radiation Therapy (IMRT)

Conventional radiation therapy uses radiation beams of uniform intensity and relies on physical blocking with lead blocks to protect surrounding structures. IMRT relies heavily on computer technology. The physician prescribes optimal tumor dose and places constraints on doses to nearby normal tissues. Then, by a process known as inverse planning, the computer calculates a plan that uses multiple beams with varied intensities to accomplish the prescribed goals. Before treatment, the physics staff carries out a complex quality assurance program

This technique offers hope of reduced toxicity of radiation treatment for selected tumor sites and brings new hope for addressing tumors that might otherwise be considered untreatable due to close proximity of vital organs to the tumor site.

Suburban is the first community facility in Montgomery County to offer this revolutionary treatment option. Currently considered one of the most advanced forms of cancer treatment available, IMRT was introduced at Suburban thanks in part to a generous grant that established the Ottenstein Center for Prostate Care and Research.

Electronic Tissue Compensation (ETC)

For selected breast cancer patients, Suburban is now using the principles of IMRT to improve dose homogeneity. Computer software produces a tailored plan combining electronic tissue compensation and electronic dynamic wedge(s) to reduce radiation “hot spots.” This may be most helpful for patients with large breasts or patients who have undergone breast reconstruction.

Transperineal Interstitial Brachytherapy

Also known as “seed therapy,” this treatment alternative for prostate cancer involves the implantation of tiny radioactive seeds directly into the prostate gland. With transrectal ultrasound and computer calculation and display capabilities, our clinicians can accurately place the seeds to deliver a high dose of radiation to the prostate, while sparing neighboring organs like the bladder and rectum. The seeds are permanently implanted where the radiation dissipates over time. Brachytherapy is an outpatient procedure and may be done alone or in combination with external beam radiation and/or hormonal therapy.
