Used SIEMENS EV-8C4

Item is listed as fair for cosmetics because it is blue but has been tested and works.
The Acuson EV-8C4 is a tightly curved endocavitary (endovaginal) ultrasound transducer designed for high-resolution imaging in women’s health, particularly for obstetric and gynecological applications. Its design and frequency range make it ideal for endovaginal studies, providing detailed visualization of pelvic anatomy.
Key Features:
Frequency Range: 4–8MHz (some references note up to 9MHz)
Type: Endovaginal/Intra Cavity probe
Applications: Endovaginal obstetrics, endovaginal gynecology, early pregnancy assessment, and other pelvic imaging
Array Type: Vector, tightly curved for optimal access and field of view in endocavity imaging
Imaging Technologies: Wideband MultiHertz imaging (user-selectable frequencies for tailored resolution and penetration), harmonic compounding (for image clarity)
Field of View: Widely curved to enhance anatomical visualization
Compatible Systems: Acuson Sequoia 512, and also compatible with other Acuson/Siemens ultrasound platforms such as the S2000 and S3000 series
Typical Use: Transvaginal studies for uterine, ovarian, and early fetal imaging.
