Ultrasound is a type of medical imaging that uses high-frequency sound waves to produce images of the inside of the body. It is a non-invasive and painless procedure that is widely used in a variety of medical settings, including obstetrics, cardiology, and gastroenterology. In recent years, there has been a surge of research activity in the field of ultrasound, with researchers exploring new and innovative ways to use this technology to improve patient care.
One area of research in ultrasound is focused on the development of new ultrasound devices and techniques that can provide more detailed and accurate images of the body. For example, researchers are working on developing ultrasound systems that use artificial intelligence (AI) to analyze and interpret images, making it easier for clinicians to make accurate diagnoses. Other researchers are developing new ultrasound probes that can be used in different parts of the body, such as the bladder or the prostate, to get more detailed images of these areas.
Another area of research in ultrasound is focused on using the technology to diagnose and treat a variety of medical conditions. For example, researchers are using ultrasound to detect and monitor conditions such as cancer, heart disease, and stroke. Ultrasound is also being used to guide medical procedures, such as biopsies and surgeries, and to monitor the progress of these procedures.
In addition to these applications, researchers are also exploring the use of ultrasound for therapeutic purposes. For example, researchers are using ultrasound to deliver targeted doses of medication to specific areas of the body, as well as to stimulate the growth of new blood vessels and tissue.
Overall, the field of ultrasound is an active and rapidly evolving area of research, with many exciting developments on the horizon. As new technologies and techniques are developed, ultrasound will continue to play an important role in the diagnosis and treatment of a wide variety of medical conditions.
Ultrasound Research
. Also, placing results in a broader perspective, validity for the median nerve would indicate that other peripheral nerves and similarly shaped anatomical structures can be measured using SWE, opening a new research direction for other peripheral neuropathies. Further testing and development will hopefully demonstrate improved visibility of structures in the CSF containing intrathecal space in a canine model and improved reliability of the arrays. Past Subprojects for Augmented Reality In building this system, we have worked extensively on what is known in the literature as augmented reality technology, especially on registration of the real and synthetic worlds, both spatially and temporally. The system used traditional chroma-keying techniques to combine rendered ultrasound data with a digitized video image from a head-mounted camera.
As there are no established predictive biomarkers available to personalize therapy selection in NSCLC, we propose the use of our high-throughput patient-derived xenograft PDX model using chick embryos in conjunction with ultrafast ultrasound to produce a phenotype-based imaging biomarker for the screening of patient-specific cisplatin resistance. However, some factors such as maternal age and number of pregnancies are common to all. In this project ECUREI in partnership with Rad Impact trained a total of 36 Midwives, nurses and clinical officers from 17 UPMB supported Health centres.

On behalf of Ministry of Health Uganda , ECUREI was awarded 122 Student scholarships in 2018 to train Government health workers in Diagnostic Ultrasound 65 , Medical Radiology 30 and Cold Chain Technology 27. Ultrafast High-Frequency Ultrasound Imaging for Chemo Sensitivity Screening in a Chick Embryo Patient-Derived Xenograft Model of Metastatic Lung Cancer Investigative team Jin Jen, M. Previous work demonstrated limited device reliability, but available operating ultrasound segments did show promise of 2D ultrasound imaging of the spinal cord and spinal vessels. Our initial ultrasound visualization system, featured the ability to display a small number of individual ultrasound slices of a fetus superimposed onto the pregnant patient's abdomen. Patients that are identified as chemo-resistant might be spared of the side effects of cisplatin therapy and could be placed on second line therapies instead erlotinib, ramucirumab or nivolumab. Hello Do you want hassle-free information and advice? Our goal is to significantly reduce the number of benign biopsies while missing no, or very few, malignant lesions.
Potential outcomes and advances In this pilot project, the study team will evaluate neuromodulatory functions of low-intensity ultrasound. We thus moved to a system that featured on-line data acquisition and off-line rendering. A total of 50 patients 29 male,21 female aged from 20 years to 70 years weight between 60 kg to 99 kg , all those complaining of persistent shoulder pain most of them were under gone routine plain s. We believe that the use of computer-augmented vision technology can significantly simplify both learning and performing ultrasound-guided interventions. Our group has developed a high-frequency array-based forward-looking ultrasound endoscope, that is suitable for guiding endoscopic procedures and providing depth resolved information.
Estrogen is known to have influence on thyroid function, and suspected to have a role in formation of thyroid nodules. If successful, our project is to provide a prototype design for a transducer and optimize ultrasound operation parameters to modulate neuronal activities without damage by heat or mechanical alterations in the brain. AR combines computer graphics with images of the real world. Active Research Projects While the Dalhousie Ultrasound research group has a robust research program, the primary focus of the research is developing ultrasound diagnostic and therapeutic tools for minimally invasive procedures. Potential outcomes and advances In this project, we will use a 3D ultrasound imaging system along with shear wave elastography to identify thyroid nodules and characterize their stiffness. The short penetration depth and high resolution, make high-frequency ultrasound particularly suitable for use in guided endoscopic surgery.
Potential outcomes and advances Imaging of the spine and its contents is today limited to advanced complex technologies magnetic resonance angiography, or MRA, fluoroscopy, CT angiography that are neither portable nor available to many patients due to many factors, including: lack of resources, patient hemodynamic instability, or during intraoperative or ICU care. Aim: The aim of study was to evaluate the accuracy of symphysis-fundal height SFH in comparison to ultrasound scan for the assessment of gestational age. These skills can then be applied within their own professional context, with a variety of obstetrical conditions, extending across many stages of pregnancy in order to save lives. The purpose of this study to estimate the correlation between placenta thickness PT and fetal age FA in normal pregnant women. Thyroid nodules are extremely common lesions and are detectable in 4 to 8 percent of adults by means of palpation, and in 10 to 41 percent by means of ultrasound. The camera video was displayed in the background; the ultrasound video images are transferred into texture memory and displayed on polygons emitted by the ultrasound probe inside a synthetic opening within the scanned patient.
Our group is focused on further miniaturizing the histotripsy transducer to less than four millimetres in diameter, so that it can be used, along with the imaging endoscope, to simultaneously image and resect deep access tumours endoscopically. This system could sustain a frame rate of 10 Hz for both display update and ultrasound video grabbing and also provides high-resolution ultrasound slice display and rendering for up to 16 million ultrasound pixels. While some lesions are clearly benign, only about 10 percent of biopsied lesions are malignant. The investigative team has engineered a unique portable device that can easily be inserted at the bedside or in the operating theater quickly, easily and at low cost, allowing for real-time assessment of spinal structures, spinal cord blood flow at multiple levels and patient pathology. Methods: The impact of different frequencies, sound pressure levels and pulse durations will be generated in the laboratory. Updates were slow, however, and the images were still not convincing.
Currently, it is hard to predict how patients will respond to treatment and thus, which treatment would benefit them most. Projects undertaken by ECUREI Rural Health related projects:ECUREI has a major focus in training for rural health. This study further begins to develop concepts and design of a catheter-based system that might allow for monitored therapeutic treatment delivery. The project was conducted by ECUREI from 2007-2011, in affiliation with Fontys University of the Netherlands. Navigation approaches are typically attempted using co-registered previously acquired MRI images, but the brain tissue shifts and distorts so severely after the skull is opened and the cranial pressure is released, that these approaches are recognized as providing only very coarse information.
The most prevalent neurosurgical guidance tools used presently are simple optical endoscopes and microscopes, but these provide no information beyond the surface of the tissue that the surgeon is about to cut through, so, the approach is still mostly performed blind. Each is described on a separate web page. Our goal is to develop a unit to which the moths do not get habituated. . Strain magnitude imaging is a novel technique that can detect sliding of two adjacent organs. Between 2010 and 2011, ECUREI, in partnership with the University of Washington Department of Radiology , with Support from General Electric GE undertook the Portable Maternal Ultrasound Initiative, in Isingiro District Western Uganda with the aim of reducing maternal mortality through training of midwives in limited obstetrical ultrasound, equipping health centers with ultrasound machines and redeploying the midwives who could now incorporate ultrasound into routine antenatal care.
