Quantitative assessment of pressure sore generation and healing through numerical analysis of high-frequency ultrasound images

Sahar Moghimi, MS, et al.

Figure 5

Prolonged unrelieved pressure can lead to the development of necrotic tissue and pressure sore formation. A noninvasive and quantitative assessment tool, which is able to monitor deeper tissue layers, is very useful for monitoring the generation and healing of pressure sores. We developed an assessment tool based on high-frequency (20 MHz) ultrasound B-mode scans. We artificially induced pressure sores in guinea pigs and monitored them for 21 days. We defined a healing function by extracting relevant parameters from the obtained images. It was demonstrated that the output of this function is capable of monitoring the healing/nonhealing behavior of the tissue under study.
