Ultrasonography01:17

Ultrasonography

8.4K
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.
During an ultrasonography procedure, a handheld device called...

Computed Tomography

9.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Ultrasound I: Abdominal Ultrasonography

2.6K
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...

Area of Science:

  • Medical Imaging
  • Biomedical Engineering
  • Musculoskeletal Diseases

Background:

  • Ultrasound Computed Tomography (USCT) is valuable for quantitative assessment of musculoskeletal (MSK) diseases.
  • Echo intensity accuracy in USCT can be reduced by non-optimal imaging conditions like probe tilt and limb eccentricity.

Purpose of the Study:

  • To develop and validate a novel echo intensity correction method for USCT.
  • To quantitatively compensate for errors caused by probe tilt and limb eccentricity in USCT imaging.

Main Methods:

  • Integration of finite element simulation and phantom experiments to create correction functions.
  • Application of correction functions to USCT images from volunteers via automated parameter extraction and intensity adjustment.

Main Results:

  • The proposed method significantly improved the uniformity of echo intensity measurements.
  • Enhanced diagnostic accuracy for musculoskeletal diseases was observed in both phantom and in vivo data.
  • Improved reliability of USCT-based quantitative diagnosis.

Conclusions:

  • The novel echo intensity correction method enhances the reliability and accuracy of USCT for diagnosing MSK diseases.
  • This technique shows strong potential for wider clinical adoption in quantitative medical imaging.
