   An L1 laminectomy is then performed: a section of the spine's bone, the spinous processes together with a portion of the lamina, are removed, like a drain-cap, to expose the spinal cord and spinal nerves underneath. Ultrasound and an X-ray locate the tip of the spinal cord, where there is a natural separation between sensory and motor nerves.

   en.wikipedia.org/wiki/Cordectomy

   Cordectomy is the surgical removal of a cord. It usually refers to removal of one or both vocal cords, often for the purpose of treating laryngeal cancer. [1] [2] The word is derived from the Greek, combining chorde and ektome meaning excision. It can be carried out by traditional surgical techniques or, increasingly, by carbon dioxide laser. [3]

   Device for both vaginal ultrasonography and abdominal ultrasonography Transvaginal ultrasonography to check the location of an intrauterine device (IUD). The examination can be performed by transabdominal ultrasonography, generally with a full bladder which acts as an acoustic window to achieve better visualization of pelvis organs, or by transvaginal ultrasonography with a specifically ...

5. Interventional radiology - Wikipedia

   Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound.

6. Therapeutic ultrasound - Wikipedia

   Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.

   These techniques are known as Magnetic Resonance guided Focused Ultrasound Surgery (MRgFUS) [32] [33] and Ultrasound guided Focused Ultrasound Surgery (USgFUS) respectively. [1] [34] MRgFUS is a 3D imaging technique which features high soft tissue contrast and provides information about temperature, thus allowing to monitor ablation.
