Transvaginal color Doppler imaging
Journal of Clinical Ultrasound, 1990AbstractTransvaginal color Doppler was used to assess circulation in pelvic vessels in a group of 64 patients including 15 patients with fertility problems, 18 patients with pelvic tumors, 2 cases of suspected ectopic pregnancy, and 29 pregnant patients with fetuses between 6 weeks and 10 weeks, menstrual age.Blood flow was successfully displayed by ...

Superficial masses with color flow Doppler imaging
Journal of Clinical Ultrasound, 1991AbstractColor Doppler imaging findings and spectral waveforms were reviewed for 21 superficial masses in which color Doppler imaging revealed flow. This series included 5 benign hyperplastic lymph nodes, 5 malignant masses, 2 staphylococcus abscesses, and 9 pseudoaneurysms.

Journal of Vascular and Interventional Radiology, 1991
The performance requirements and operational parameters of a color Doppler system are outlined. The ability of an operator to recognize normal and abnormal variations in physiologic flow and artifacts caused by noise and aliasing is emphasized. The use of color Doppler flow imaging is described for the vessels of the neck and extremities, upper abdomen

Reproducibility of color Doppler imaging
Graefe's Archive for Clinical and Experimental Ophthalmology, 2009The aims of this study were: (1) to determine the intra-subject and inter-observer variability of color Doppler imaging (CDI) measurements and readings of the retrobulbar blood vessels, (2) to compare the difference invariability of CDI parameters in non-glaucomatous controls versus glaucoma patients, and (3) to provide calculations of minimum sample ...

AbstractBy simultaneous processing of frequency, phase, and amplitude information in the backscattered ultrasound signal, new instruments now permit the realtime display of highâresolution grey scale images of tissue combined with the simultaneous display of flow data from vessels within the scan plane.

Color digital echo/doppler image presentation
Ultrasound in Medicine & Biology, 1981Abstract Arterial occlusive disease in peripheral blood vessels can be evaluated with an ultrasound scanning system designed to generate real-time cross sectional tissue images and to assess the character of blood flow at any point using multi-gate Doppler methods. A new-generation echo/Doppler system.

Assessment of Color Doppler Imaging Quality
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992This paper describes a method for assessing some features representative of color doppler imaging quality. This method applies to slow continuous flow and permits measurements of the minimal velocity which can be represented by a color and the difference between the real velocity and the calculated velocity.

Color Doppler Imaging of Retinal Diseases
Survey of Ophthalmology, 2010Color Doppler imaging (CDI) is a widely used method for evaluating ocular circulation that has been used in a number of studies on retinal diseases. CDI assesses blood velocity parameters by using ultrasound waves. In ophthalmology, these assessments are mainly performed on the retrobulbar blood vessels: the ophthalmic, the central retinal, and the ...

Two-color reduced-Doppler ion imaging
The Journal of Chemical Physics, 2006We demonstrate a two-color reduced-Doppler probe for ion imaging that, in many applications, offers advantages over conventional 2+1 resonance-enhanced multiphoton ionization detection. Using counterpropagating beams of two different colors, one of which is broadband 266nm, we achieve convenient and sensitive D atom detection without the need for ...

Color doppler applications in hepatic imaging
Clinical Imaging, 1998Color Doppler sonography is an important modality in the non-invasive evaluation of the liver. It is commonly used to evaluate vascular changes which accompany cirrhosis. Doppler techniques are also used to evaluate patients who have undergone liver transplantation or transjugular intrahepatic portosystemic shunt (TIPS) placement. This review describes
