High Frequency Probe        


HF35-50 High Frequency Ultrasound
Probes and Transducers

The HF35-50 compact, handheld probes are designed to be used with a soft plastic scleral shell designed by OTI, and offer a scan width and depth that is the best in ophthalmology.

The standard HF35-50 system comes with choice of a 35 MHz or 50 MHz probe. The lightweight probes are interchangable and the standard system can be upgraded to include both the 35 MHz and the 50 MHz probe. A 20 MHz probe is also available for use with this system. The probe or probes chosen will depend on user preference.


35 MHz Probe

The 35 MHz Probe allows imaging of the cornea and the entire anterior segment for phakic IOL-related measurements. This probe provides very bright images with excellent penetration and is currently the most popular choice of probe with this system.

50 MHz Probe

The 50 MHz Probe is the best choice for pathology such as iris or ciliary-body tumors, cysts or imaging of the cornea. It offers better resolution with some loss of depth and brightness.

20 MHz Probe

A 20 MHz high resolution probe is offered as an option on the HF35-50 for posterior segment scanning. This probe provides a more detailed view of vitreous/retina/choroid structures.

Transducers

While the option of purchasing two entirely separate probes is most common, in the case of both the 35 MHz frequency and the 50 MHz frequency the option to purchase only one probe body and two separate transducers is available. The small metal transducer can be detached from the probe body so one probe body is necessary.

The transducers are changed by manually unscrewing one and screwing in the other. This option is available for the user seeking a more economical means of obtaining both probe frequencies.

This option is not available with the 20 MHz Probe as the probe and transducer are are housed within a closed probe body and can not be separated.

 




The HF35-50 comes with a set of 3 custom made immersion cups. These soft plastic scleral shells have been custom designed by OTI to ensure a custom fit and ease of use.
