Hours of Service:
Overview of CT
Monday - Friday: 7:30 AM – 7:00 PM (On-call emergency services after hours). All outpatient CAT Scans are to be scheduled through our central scheduling line at (207)777-4049.
The dynamic CT Scan Department offers two scanners. Both are accredited by the American College of Radiology. The GE Optima 660 is a 64 slice scanner and the GE Lightspeed is a 16 slice scanner. Both employ advanced technology to obtain the best images at the lowest level of radiation. The scanners are capable of detecting a wide range of pathology throughout the body. The scan can be performed in either the axial plane or helical (spiral) which can then be reconstructed for a 3-dimensional image.
The GE Optima 660 was installed in August 2012. It is an outstanding CT scanner because the acquisition speed is rapid and the image resolution is top of the line. GE uses the very latest advances in technology to reduce the amount of radiation needed for superb images which also reduces both the exam time and the amount of IV contrast needed for the CT exams.
