ANALISIS JEDA WAKTU PEMBACAAN IMAGING PLATE TERHADAP KUALITAS CITRA PADA PHANTOM THORAX MENGGUNAKAN COMPUTED RADIOGRAPHY

---

Technically, an Imaging Plate (IP) that has been exposed to radiation will store a latent image within it. According to Seibert (2006), the latent image on the IP can persist for a considerable time after exposure. This is due to the exponential decline of trapped signals over time, caused by spontaneous phosphorescence. In general, an IP may lose approximately 25% of its stored signal within 10 minutes to 8 hours post-exposure, after which the rate of signal degradation slows down. Furthermore, this research applied a quantitative method with descriptive analysis approach and was undertaken in May 2025 at Laboratory of Health Polytechnic, Ministry of Health, Jakarta II. The samples consisted of thoracic phantom images taken with varying time delays ranging from 0 minutes to 12 hours. As for the data, they were collected by performing experiments with time delays in imaging plate reading at 30-minute intervals, followed by analysis using histogram graphs. The results of the research showed inconsistent changes in image quality relative to the length of the delay in imaging plate reading. Although a decrease in mean values was observed at certain time points, the overall decline was neither linear nor continuous. A noticeable reduction in image quality indicated by a drop in the average intensity values on the histogram occurred within the first two hours following exposure.
