Model PVB
Interventional w/high contrast Rubber-based
|
|
The PVB series have been designed to evaluate the acoustic performance of an intra-arterial ultrasonic transducer just prior to examining a patient.
They are constructed of a tissue mimicking rubber-based material.
The phantoms are housed in a chemical resistant, injection molded polypropylene shell to permit sterilization be means of autoclaving. |
The Models PVB 1 & 2 differ only in their overall size.
The Models contain five cylindrical cavities.
A 4.0 mm diameter central cavity is surrounded by four 2 mm cavities located at 90° intervals around the central cavity.
The edge to edge spacing of the four 2 mm cavities relative to the central cavity is 4, 3, 2 and 1 mm.
The 2 mm cavities in the Model PVB-3 mm are filled to create gray scale targets.
Any single gray scale may be selected, ranging from +15 to -15 dB relative to the background material.
Lifetime warranty. |
