Main Article Content
Abstract
Background: Breast ultrasound plays a vital role in detecting breast lesions. However, breast ultrasound requires the expertise and great skills of medical personnel. However, training medical personnel on live patients is still impractical. Therefore, simulation-based training on a phantom is necessary.
Objectives: To develop a breast model for lesion detection for use in ultrasound breast training.
Methods: Firstly, the samples of the gelatin-based model were constructed in five samples in different concentrations of gelatin, and then a sample that was closest to the elastic modulus of breast tissue was selected to make a model. Three breast models were made including a non-pathologic model, a pathologic model with a paraffin wax mass, and a fluid cyst model. After that, 36 female 4th-year radiologic technology students were asked to rate their skills before and after training and their satisfaction.
Results: The result showed that the breast models were successfully made of gelatin, which represents a soft and elastic texture, is stable at room temperature, and nearly matched the elastic modulus of breast tissue. The evaluation of our breast model showed that it was a good training model, resulting in a significant increase in exercise skills after using the breast model (p<.05). Moreover, overall breast model appearance and pilot tests showed a good level of satisfaction.
Conclusions: Our gelatin-based breast models can be used as a training tool for practicing breast ultrasound examinations.
