Depending on the goal of the procedure, a pelvic ultrasound can also be called a bladder ultrasound, pelvic gynecologic sonogram, or obstetric sonogram.
metal objects show up on a ultrasound scan because when it hits a new media, It will reflect and slow down, so compressed objects will show easily on ultrasound scans.
Obstetric ultrasound has been generally accepted as being quite safe for babies in the womb. Though small studies have shown that there may be some adverse neurological effects on the baby, no large studies have ever been performed to prove or disprove this finding.

An ultrasound is given at 20 weeks unless you at high risk for a miscarrage.
By performing repeated scans over time, much like the frames of a movie, ultrasound can also reveal movement, such as the motions of a fetus. This technique is called real-time ultrasound.
Primary tests include CT scans, MRI's, Endoscopic Ultrasound, laparoscopy and biopsy.
Four different modes of ultrasound are used in medical imaging: A-mode. This is the simplest type of ultrasound in which a single transducer scans a line through the body.
Ultrasound scans are done - for instance to look at the foetus during pregnancy
yeah its safe i had 2 scans in 2 days and everythings fine. I asked the doctor and they said theres nothing that suggests scans can affect the baby.
In B-mode ultrasound, which is the most common use, a linear array of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen.
Regardless of the type of scan used and the potential difficulties encountered, ultrasound remains faster and less expensive than computed tomography scans (CT).
