A Novel Ultrasound Imaging Assistance UI: Using Marker‐Based Coordinate System for Real‐Time Breathing Monitoring and Probe Positioning

“…The previous UI [8] is designed with two screens to guide the probe's positioning and angling, respectively. Each screen contains a pink square and a green square.…”

“…The HTM named G T S is formed as (8), where the left superscript G and the right subscript H in (8) around T mean transformation from H coordinate system (a sample coordinate system) to the global coordinate system, in (6) mean only rotation from H coordinate system to the global coordinate system, and in (7) mean origin coordinate of the H coordinate system under the global coordinate system.…”

“…This section aims to verify whether the UI system proposed in this method can efficiently guide the operator to obtain accurate ultrasound images of the subject and whether more accurate ultrasound images can be acquired compared to those using a similar auxiliary from the previous UI [8].…”

“…This paper first details the algorithms and hardware solutions developed to support the proposed UI. Then the experiment is conducted to evaluate our UI performance in comparison to the previous methods [8] and validate the respiratory level measured by our breath monitor method. In the comparative experiment, the same group of novices, with no prior experience in ultrasound operation, were instructed to use both the UI designed by the previous method [8] and the UI proposed in this study in a crossover order to capture ultrasound images.…”

The deviation between the probe positions used by the novices and the expert during ultrasound image capture was compared, aiming to evaluate whether the proposed UI provides more intuitive guidance for novices and whether it is more conducive to assisting them in substituting for some of the tasks of the professional ultrasound expert.…”
