Ultrasound image analysis software uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women. Uses of ultrasound are much broader, however. Other important uses include imaging the abdominal organs, heart, breast, muscles, tendons, arteries and veins. The real time moving image obtained can be used to guide drainage and biopsy procedures. Doppler capabilities on modern scanners allow the blood flow in arteries and veins to be assessed.

Intraoperative imaging systems are generally used in image-guided surgeries. Pre-operative images are less useful for the surgeon during surgery as the surgery target often tend to shift from previous known place during surgery. In present days, surgeons can operate more accurately with the help of intraoperative imaging as it help available real-time images of the surgery that help in locating the exact position of target. It helps in precise monitoring and control of surgical procedure.

PET/CT is a new modality with integration of PET and CT systems. Positron emission tomography-computed tomography (PET-CT) is a scientific diagnostic technique that is used to analyze tissue metabolism. This technique makes use of an X-ray CT scanner and a PET scanner. The combination of PET-CT scan gives us the exact location of the organ's abnormal metabolic activity within the body and gives diagnostic accuracy. With a radioactive tracer, the patient is sprayed with a glucose solution, and the organs ingest the tracer and are thus diagnosed.
