“…A graphical user interface (GUI) is designed to visually guide paramedics to find the initial probe placement, show acquired 3D images, and display ultrasound probe navigational commands. The 3D ultrasound images are displayed by multiplanar reformatting and ray-casting techniques [20]. The GUI also provides tools for paramedics to give the CSoCIPP and CSoPPR signals.…”

In this paper, a new computer-assisted ultrasound probe placement system is introduced to guide paramedics and first responders to conduct abdominal ultrasound imaging for diagnosing trauma patients in emergency situations where specialists are not present. Recently, tele-Sonography has been employed to supervise paramedics by remote experts to perform ultrasound scan for triaging, although its utility is limited by unavailability of fast internet connectivity in remote regions. In the proposed solution of this paper, a paramedic is first instructed to place the ultrasound probe on an initial placement for imaging an organ of interest. Then, a 3D ultrasound image is acquired and processed to determine the organ's shape misalignment with respect to a reference alignment. Afterward, the organ's shape misalignment is used to estimate the probe misalignment, and then, a probe placement command is generated to guide the paramedic. This process iterates until a correct organ's view of interest is obtained. As the advantage of the proposed solution over the existing technique, the proposed solution does not require a fast internet connectivity and a dedicated remote specialist to conduct ultrasound imaging by a paramedic. The utility of the proposed solution is evaluated for a case study on the right upper quadrant (RUQ) view, which has a paramount importance in triaging trauma patients. Accuracy and robustness of the proposed solution is verified using actual and simulated 3D ultrasound images of the RUQ view.

“…The design complexity of the plane varies from the floor of a container (Prager et al, 1998), a plexiglass plate (Rousseau et al, 2005), a nylon membrane (Langø, 2000) to a precision-made Cambridge phantom (Prager et al, 1998) and its variants (Varandas et al, 2004;Ali and Logeswaran, 2007).…”

Freehand three-dimensional ultrasound is a technique for acquiring ultrasonic data of a 3D volume by recording the trajectory of the ultrasound probe using a position sensor. In planning and registration, a freehand ultrasound systems is used to track a two-dimensional probe. Probe calibration is necessary to find the rigid body transformation from the coordinate system of the B-scan to that of the mobile part of the position sensor. Numerous techniques for this have been developed over the past decade. In this review, we give a comprehensive description of existing calibration techniques and classify them according to the mathematical principles on which they are based. We give a thorough analysis of these approaches based on their accuracy, ease of use, reliability, and speed of calibration. To ensure consistency, these comparisons are done by the authors based on experimental results and not on figures quoted in previous papers.

“…A system developed at the University of Leeds [1], is focused on needle guidance and uses simulated ultrasound data generated from CT scans. VOLUS [2] uses similar data capture techniques, but focuses on 3D surface mapping of the heart. The UltraSim [3] system has a fullsize mock ultrasound imaging system and uses mechanically-controlled acquisition of ultrasound data.…”

Ultrasound imaging relies heavily on the skills of the sonographer, requiring extensive hands-on training. The Interactive Training System for Medical Ultrasound is an inexpensive, software-based training system, in which the trainee scans a lifelike manikin using a sham transducer, containing a 6 degree of freedom (DoF) tracking sensor. The observed ultrasound image is generated from a pre-stored 3D image volume and is controlled by the tracking sensor's position and orientation. Based on the selected 3D volume, the manikin may represent normal anatomy, exhibit a specific trauma or present a given physical condition.An Ascension trakSTAR tracking system provides accurate position and orientation tracking, and the components of the tracking system are embedded into a manikin and a transducer shell to remove the awareness of the tracking system. The training system provides a realistic scanning experience. Successful methods of data capture have been developed for acquiring data volumes composed of multiple transducer sweeps. Training data sets were subsequently generated from these sets of overlapping individual 3D scans on phantoms and a human subject. The ultrasound training system can provide cost-effective and convenient training of physicians and sonographers.
