Ultrasound fantoms are essential tools used to evaluate and calirate ultradźwiękowe systemy maing. They simulate human tissue performancies, allowing for consistent testing and quality control. Proper design and d calibration of these phantoms ensure crisate and reliable image performance.

Design of Ultrasound Phantoms

Te design of ultrasonograph fantoms involves selecting materials that mimimic thee acoustic properties of human tissues. These properties include sound speed, attenuation, and backscatter. Common materials used are gels, plastics, and specifized composites.

Phantoms are often constructant with embedded precises or structures to evaluate specific imagine precires such as resolution, contract, and depth prisacy. The geometry and composition of these precials are critical for effective system testing.

Procedura Calibration

Kalibration of ultrasonograms systems using fantoms involves addisting systems settings to match known standards. This process ensures that measurements such as distance, size, and contrast are e customate. Regular calibration helps maintain system performance over time.

Kalibration procedury typically include measuruing thee speed of sound, assessing axial and lateral resolution, and verifying contrast resolution. These tests are perfomed using standardized phantoms designed for calibration depeles.

Quality Control i Maintenance

Rutynowe kontrowersje jakościowe involves periodic testing of ultradźwiękowe systemy with phantoms to devit any devitions from m expected performance. This process helps identify issues early andd ensures consistent imagine quality.
