Services We Provide
Radiation Therapy
The VitalBeam machine is designed to apply precise dosage quickly and give patients their time back—the system is built with human needs in mind. It is designed to treat cancer wherever it’s found in the body and flexible enough to meet the clinical needs of our patients as well. Our equipment provides a variety of treatment techniques including 3D conformal radiation, intensity modulated radiation (IMRT), image guided radiation (IGRT), stereotactic brain (SRS) and body radiosurgery (SBRT) to address a broad range of cancer case. It delivers high precision dosage control with sub-millimeter accuracy ensuring conformity. These streamlined treatments enable seamless system operation rendering it safe and reliable.
Imaging
The Toshiba Aquilion 16 CT scanner is designed with a large aperture, a slip-ring gantry and an extra-wide couch for maximum patient comfort. The Aquilion 16 is a whole body CT scanner that provides excellent image quality and performance. It is equipped with a quantum detector that will provide images with true isotropic resolution in a small field of view with 0.5mm which is the industry’s thinnest slice width for maximum detection of suspicious tissue. When using this scanner to perform an exam, we are able to scan in one plane which reduces radiation exposure to our patients.
HDR Brachytherapy (Internal Radiation Therapy)
High-dose rate (HDR) brachytherapy involves placing a protected source of high energy radiation directly within the tumor and using specially designed applicators, such as radioactive plaques, needles, tubes, wires, or small "seeds" made of radionuclides. We often use HDR brachytherapy to treat superficial skin cancers and other tumors in body cavities such as nose, pharynx, vagina, etc.
Nursing Services
Our nursing staff provides individual care and attention to our patients and their families. We take an individual investment of time and compassionate care before, during and after our patients treatment course. We provide vital checks upon each visit and are acutely involved discussing the course of treatment, side effects and any medications where applicable. We also advise and consult on other modalities of good health such as diet, exercise and intellectual stimulation. The holistic approach to our patients' well being and the well being of their families is our primary mission.
