Page 3: Introduction
The acoustic properties of all biologic and non-biologic materials are affected by temperature variations. Most diagnostic imaging systems and tissue-mimicking phantoms are calibrated at room temperature, commonly referred to as 23°C. To ensure measurement accuracy ATS incorporates a thermometer strip affixed to the outside surface of the phantom housing. - Page 4 Scan Surface 1 Scan Surface 3...

Page 6: Dead Zone
DEAD ZONE Description and Reason For Testing The dead zone is the distance from the front face of the transducer to the first identifiable echo at the phantom/patient interface. In the region of the dead zone no clinical data can be collected. The dead zone occurs because an imaging system cannot send and receive data at the same time. -
Page 7: Horizontal Measurement Calibration
Testing Procedure Note: The Model 535-H Basic QA phantom provides two scanning surfaces used to evaluate horizontal measurement calibration. Linear array scanning systems should use #1 scanning surfaces. Sector scanning systems should use #3 scanning surfaces. -
Page 8: Axial And Lateral Resolution
Testing Procedure In the Model 535-H scan surface #1 and #3 are used to evaluate axial resolution at depths of 5.5 and 11 cm. To evaluate lateral resolution, scan surfaces #2 and #4 are used, at depths of 4.5 and 16.5 cm. -

(geometry) of the reflecting object, and electromagnetic interference from the local surroundings. Testing Procedure The Model 535-H is provided with two sets of anechoic target structures, at two depths from scan surface #1. The ability to use all four scanning surfaces allows measurements to be obtained at 6 depths. -
