Probe Lens for Toshiba PST30BT Ultrasound Transducer
Brand: Toshiba Model: PST30BT Series: probe lens Condition: compatible new
1. In-depth Understanding of the PST-30BT Transducer Characteristics:
-
Transducer Type: Recognize that the PST-30BT is a phased array transducer. The acoustic lens design for phased array probes is critical for beam formation and scanning patterns.
-
Frequency Range: Recall the operating frequency range of the PST-30BT (2.0 - 4.8 MHz). The replacement lens's acoustic properties must perform optimally within this range to ensure image quality.
-
Application Area: Confirm that the PST-30BT is primarily used for cardiac and transcranial imaging. These applications demand high penetration, resolution, and spatial accuracy, making lens quality paramount.
-
Original Lens Specifications: If feasible, try to obtain the detailed specifications of the original PST-30BT lens, including material composition, sound velocity, attenuation coefficient, geometric shape, and radius of curvature. This will serve as a crucial reference for selecting a replacement.
2. Evaluating the Technical Specifications of the Replacement Lens:
-
Acoustic Impedance Matching: The acoustic impedance of the replacement lens should closely match that of human tissue and the transducer crystals. This minimizes reflection at the interfaces and maximizes energy transmission efficiency.
-
Sound Velocity and Attenuation: The sound velocity and attenuation characteristics of the lens material will affect image clarity and penetration depth. Opt for materials with appropriate sound velocity and low attenuation.
-
Focusing Properties: For phased array transducers, the lens design works in conjunction with electronic focusing. The replacement lens's geometry and curvature must support the transducer's electronic scanning and focusing capabilities, ensuring a good focal point at various depths.
-
Bandwidth: A broadband lens typically supports a wider frequency range, offering better axial resolution. Consider if the bandwidth of the replacement lens meets your clinical needs.
-
Uniformity: The material and manufacturing process of the lens should ensure uniform acoustic properties, preventing artifacts in the image due to internal variations within the lens.
