Summary
This study introduces a novel navigation system using sonography for soft tissue surgery, improving accuracy and real-time visualization. The system bypasses the need for CT/MRI, offering precise guidance for head and neck procedures.
Area of Science:
- Medical technology
- Surgical navigation
- Diagnostic imaging
Background:
- Conventional CT/MRI navigation is limited in head and neck soft tissue surgery due to tissue shifts.
- Invasive procedures cause changes not visualized by traditional methods.
Purpose of the Study:
- To develop and evaluate a novel navigation system for sonography in soft tissue surgery.
- To overcome limitations of CT/MRI-based navigation in dynamic surgical environments.
Main Methods:
- Development of a navigated ultrasound scanner and surgical instrument integrated with custom software.
- Real-time visualization and guidance for surgical procedures.
Main Results:
- The prototype navigation system achieved a system deviation of less than 1 mm.
- Demonstrated good handling properties and accurate, rapid instrument guidance in a model setup.
Conclusions:
- The navigated ultrasound system eliminates the need for additional CT or MRI imaging.
- Provides real-time visualization of tissue changes, ideal for invasive soft tissue procedures.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
