利用热释电晶体和可拆卸的真空法兰实现了一种可更换靶的掌上型X射线管。通过用碳带将目标金属固定在黄铜载物台上，可以很容易地更换目标金属。当用银和钛板（面积：10 mm（2））作靶时，用电子轰击靶90 s，可清楚地观察到银Lα和钛K线。的强度是相同的或高于先前报道的热释电X射线管。通过将黄铜载物台和不锈钢真空法兰分别替换为碳载物台和玻璃管，X射线管（不锈钢和黄铜）中的铬、铁、镍、铜和锌K线消失。
A target changeable palm-top size x-ray tube was realized using pyroelectric crystal and detachable vacuum flanges. The target metals can be exchanged easily by attaching them on the brass stage with carbon tape. When silver and titanium palates (area: 10 mm(2)) were used as targets, silver Lα and titanium K lines were clearly observed by bombarding electrons on the targets for 90 s. The intensities were the same or higher than those of previously reported pyroelectric x-ray tubes. Chromium, iron, nickel, copper, and zinc K lines in the x-ray tube (stainless steel and brass) disappeared by replacing the brass stage and the stainless steel vacuum flange with a carbon stage and a glass tube, respectively.
