Abstract. The paper presents a new robust and fully automatic technique for calibration of three-dimensional (3D) freehand ultrasound. 3D Freehand ultrasound involves mounting a position sensor on a standard probe. The echo graphic B-scans can be localized in 3D, and can be compounded into dimensions. On the other hand, especially for quantitative use, this process requires a calibration procedure that fixes its accuracy and practicality. Calibration aims at defining the transformation (translations, rotations, scaling) among the coordinates system of the echo graphic images and the coordinate system of the localization system. We put forward a robust and fully automatic calibration method based on the Hough transform and robust estimators.

In this work, we aim at closing the gap in the workflow of existing robotic support systems in order to allow for completely automatic 3D ultrasound acquisitions using a robotic imaging system. We present the pathway towards an autonomous robotic ultrasound system to help clinicians during interventions by performing multiple and especially reproducible examinations based on pre-interventional planning. As it is mostly non-invasive and has a real time capability and a comparatively low cost nature, 2D ultrasound is popular. Its major shortcoming is its weak capability of issuing quantitative

The process of becoming an ultrasound technician can be one that is intimidating. However, it doesn’t have to be. With the help of an organization called American Registry for Diagnostic Medical Sonography (ARDMS), those seeking to be a sonographer can achieve their goals. Although there are many steps to take, it can be done. This paper will help instruct individuals who wish to go through the sonography principles and instrumentation (SPI) examination (Sonography Principles & Instrumentation [SPI], (2015).
The Diagnostic Sonography more commonly known as Ultrasound is a medical procedure in which you use high frequency sound waves to produce visual images of organs tissues or blood flow inside the body. Ultrasound is regularly known as the procedure used to examine women who are expecting. Although, Sonography is used in many different ways other than for expectant mothers. Sonography is also used to detect such things as heart disease, heart attacks, and vascular disease that can lead to stroke. (SDMS, 2010) Moreover, Sonography is also used to examine breasts, abdomens, female reproductive systems,
Being able to identify lumps, swelling, tissue damage, cysts, and the overwhelming news of the sex of a baby all have something in common, an ultrasound. Swelling of the spleen, kidney stones, blood clots, aneurysms, cancer and so much more can be identified through the works of an ultrasound’s imaging technique. Ultrasound involves many concepts, procedures, and careers. The amount of medical possibilities involved with ultrasounds is useful in major medical diagnostics. The field of ultrasounds and career opportunities are widely growing. As medical careers flourish, needs for technicians in many fields of medicine are increasing. Instead of a doctor choosing complex and risky surgery to find out problems within the body, they can now
Ultrasound imaging has many uses in medicine, from confirming and dating a pregnancy to diagnosing certain conditions and guiding doctors through precise medical procedures
Sonography is a non-invasive medical procedure that uses the echoes of high-frequency sound waves to construct an image of internal organs or body structures. The employment rate is is expected to grow 26 percent from 2014 to 2024. Since ultrasound is non-invasive, it is more encouraged than other methods so the career is always in demand. Diagnostic medical sonographers duties are to prepare and maintain diagnostic imaging equipment, taking a patients medical history, answering questions about the procedure, operating the equipment, review images and test results, know the difference between normal and abnormal images, analyze diagnostic information, record findings, and keep track of patient records. Hospitals, offices of physicians, medical
Diagnostic medical sonography is a profession where sonographers direct high-frequency sound waves into a patient’s body through the use of specific equipment to diagnose or monitor a patient’s medical condition. As described by the Bureau of Labor Statistics, this examination is referred to as an ultrasound, sonogram, or echocardiogram. The high-frequency sound waves emitted from the handheld device, called a transducer, bounce back creating an echo and therefore produce an image that can be viewed on the sonographers computer screen. This image provides the sonographer and physician with an internal image of the patient’s body that will be used in the diagnosis. The most familiar use of ultrasound is used in monitoring pregnancies
2D Ultrasound Images: Also known as sonography, ultrasounds work by using sound waves to develop an image of what's inside the body—in this case, a baby! When you think of a stereotypical pregnancy ultrasound, this is probably what comes to mind. The 2D ultrasound technique has been used for years and provides a two-dimensional,
The increasing demand for diagnostic imaging and therapeutic technology promises an exceptional outlook for sonographers. The majority of diagnostic medical sonographers are employed by hospitals, but accessibility to low-cost portable ultrasound equipment has led to a growing number of career opportunities at clinics and diagnostic centers (Rising Demand for Diagnostic Medical Sonographers). They now have access to portable units as small as laptop computers making commuting from hospital bedsides to clinical practices easier. Since some sonographers make their own schedules through contracts with clinics, these portable units make traveling much more convenient.
Diagnostic medical sonographers who are also known as ultrasound technologists, play a very pivotal role in the health industry. Sonographers use specialized 3D imaging machines to generate images of internal body organs and structures which works hand-in-hand with doctors in gathering the necessary data needed for a diagnosis (Reece & Hobbins, 2007). Diagnostic medical sonography has many different branches you may pursue such as obstetrics/gynecology, breast sonography, cardiovascular sonography, and abdominal sonography to name a few (Brent, Jensh, & Beckman, 1991). The limits of authority and legislated scope of practice for sonographers has recently been revised in May 2013 by sixteen representatives from multiple sonography organizations throughout the country (2016). A diagnostic medical sonographer must be a qualified individual who is academically credited as well as clinically skilled before they begin to practice. Affirmation, demonstration, continuing education as well as re-certification from a nationally accredited organization is required for every sonographer (2016).

Diagnostic medical sonographers play a key role in the health care team and often work alongside doctors, nurses, and other technologists. They prepare patients by explaining the procedure and collect necessary patient history information prior to examination. An ultrasound is then performed, which is a non-invasive process that enables sonographers to send high-frequency sound waves into the body. The return signals are then analyzed to help visualize internal organs in 2D, 3D or 4D. These images help physicians with medical diagnoses and are also used for monitoring pregnancy. An ultrasound is often executed on many different areas of the body including the abdomen, pelvis, tissues, and vascular and cardiac systems. A DMS may also be required
However, in order to diagnosis a patient with a ultrasound machine you have to get some training either from a medical school, a medical program or a university. The minimum requirement is a Bachelor’s degree to become a Sonographer followed by a certification of the field your entering. Several merits that may be required are a good science background, computer skills and mathematics. You can try and get an internship to a medical facility or a hospital to get a hands on training. Although there are different ways of becoming a medical Sonographer for example in Eileen’s case she chose to take the alternative route by taking an apprenticeship with a vascular surgeon who is
A Sonographer operates ultrasound equipment which is a scanning technology which uses sound waves to create images of soft and hard tissues. Mainly known for performing fetal and pregnancy inspections and check-ups, the technology has been adapted to performing diagnostics of practically every part of the human body (Szabo, 2004). Today ultrasound has grown into a powerful medical screening tool which medical professionals turn to for accurate internal imaging to determine the extent of the patient’s conditions.
