Computed Tomography01:10

Computed Tomography

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...
Ultrasonography01:17

Ultrasonography

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 a...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

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
  • Acoustics
  • Biomedical Engineering

Background:

  • Pulse-echo ultrasonic imaging is standard in medicine but limited by poor spatial resolution (approx. 200 μm at 15 MHz).
  • This resolution limit hinders the detection of small, clinically significant features like microcalcifications.

Purpose of the Study:

  • To develop and demonstrate a new continuous-wave ultrasound imaging method.
  • To achieve superior spatial resolution beyond the limitations of conventional pulse-echo techniques.

Main Methods:

  • Continuous-wave ultrasound is transmitted to insonate a rotating object.
  • Amplitude and phase of returned signals are coherently processed.
  • Doppler tomographic imaging reconstructs the object's backscatter field.

Main Results:

  • Numerical simulations show spatial resolution up to 0.19 wavelengths.
  • Experimental validation using string and cylindrical phantoms.
  • Accurate localization of thin copper wires and good shape approximation of cylindrical phantoms were achieved.

Conclusions:

  • The developed continuous-wave Doppler tomographic ultrasound method offers significantly improved spatial resolution.
  • This technique shows promise for enhanced detection of small lesions in medical imaging applications.
  • The method is validated through numerical simulations and experimental phantom studies.
