Image optimisation is essential for acquisition of quality images in ultrasound and critical to the diagnostic ability of the examination. These skills are taught to sonography students early in their education, but research has found that retention of non-rehearsed knowledge decreases significantly after a year. The aim of this study was to determine which optimisation tools (knobology) final year sonography students use, how often and why they chose to adjust parameters and assess barriers to optimisation of knobology tools.
A prospective study using data from an anonymous online survey of 34 final year sonography students.
Survey results showed that 19/34 (55%) of students "frequently" optimise all Doppler settings and 23/34 (67%) of students "frequently" optimise basic parameter settings (depth, focus, time gain compensation). Time constraints (24/34 (70%)) and loss of gained knowledge of sonography principles and instrumentation (17/34 (50%)) were the major barriers to the use of knobology. The majority 28/34 (82%) believed they would benefit from further training.
This study demonstrates that although most students are optimising settings to improve image quality, sonography principles and instrumentation knowledge loss and time constraints prevent students from maximising machine capabilities. This study supports the need for further training prior to final year clinical placement.
图像优化对于在超声检查中获取高质量图像至关重要，并且对于检查的诊断能力至关重要。这些技能在超声检查专业学生教育的早期就会教授给他们，但研究发现，一年后未经复习的知识留存率会显著下降。本研究的目的是确定最后一年的超声检查专业学生使用哪些优化工具（旋钮操作）、使用频率以及他们选择调整参数的原因，并评估优化旋钮操作工具的障碍。
一项前瞻性研究，使用了对34名最后一年超声检查专业学生进行的匿名在线调查数据。
调查结果显示，19/34（55%）的学生“经常”优化所有多普勒设置，23/34（67%）的学生“经常”优化基本参数设置（深度、焦点、时间增益补偿）。时间限制（24/34（70%））和超声检查原理及仪器知识的遗忘（17/34（50%））是使用旋钮操作的主要障碍。大多数28/34（82%）的学生认为他们将从进一步培训中受益。
本研究表明，尽管大多数学生正在优化设置以提高图像质量，但超声检查原理和仪器知识的遗忘以及时间限制阻碍了学生充分发挥机器的能力。本研究支持在最后一年临床实习前进行进一步培训。
