Endoluminal probes specifically designed for transrectal ultrasonography are used for detailed imaging of anatomical regions like the prostate gland.
To achieve the necessary high resolution for these superficial structures, these probes operate at specific frequencies.
The typical operating frequency for an endoluminal probe used in transrectal ultrasonography is 7.5 MHz.
This frequency offers an optimal balance between image detail and penetration depth for visualizing the targeted anatomy.
