An accomplished radiologist and former clinical instructor, Dr. Alan H. Porter is the clinical director of Porter Radiation Oncology. Dr. Alan Porter has been named among the Best Doctors in America in each of the last 14 years. He is proficient with various tomotherapy procedures, including the innovative stereotactic body radiotherapy (SBRT).
Stereotactic radiotherapy is an advanced therapeutic procedure that treats small-sized tumors through precise image-guided delivery of the highest possible dose of radiation to abnormal tumor cells, while preserving healthy cells around the tumor. The procedure does not require an incision. Stereotactic radiotherapy starts with scanning (CT, MRI, or PET) of the area of the body that requires treatment - often done in the radiotherapy department. The information from the scan goes directly into a radiotherapy planning computer which models radiation beams that follow the shape of the tumor precisely.
Special types of small metal markers, called fiducial markers, may be placed near the tumor site. To place these markers, a doctor or radiotherapist inserts needles on the areas of the skin that are above the tumor. The insertion is guided by an ultrasound scan to ensure precision. Small gold pellets are placed at each site.
These markers will be seen on x-rays and other scans during treatment (which may be days or weeks later). When fiducial markers are used, x-rays or scans will be taken every day before treatment.
