Ultrasound uses sound waves to produce images of soft tissues. Different transducer configurations like linear array and sector scan are used for specific areas. Patient preparation involves cleaning and applying coupling gel. Digital radiography produces digital images in DICOM format for accurate, reliable images. Computed tomography produces cross-sectional images using X-rays and detects small tissue differences. Magnetic resonance imaging uses magnetic fields and radio waves to produce detailed images without radiation. Nuclear scintigraphy traces radioactive substances injected into tissues to localize problem areas.
