-
摘要: 目的:探索在医用胶片上对肋软骨CT影像显示其真实大小的胶片打印技术。方法:选取31例患者肋软骨CT影像资料,经影像后处理,胶片采用14英寸×17英寸(35 cm×43 cm)规格,计算EBW工作站显示屏主影像显示区和14×17胶片上实际影像显示区之间的比例关系,制成10 cm和5 cm两个长度规格的实物比例尺。打印时将胶片以2×2分格呈4幅图像布局,选取5 cm实物比例尺打印单根肋软骨横轴面或矢状面影像;以1×1分格呈单幅图像布局,选取10 cm实物比例尺打印全部前肋弓(含肋软骨)的三维影像。选取右侧第6肋软骨升部、横部的长度,升部横部连接处宽度、厚度,肋软骨胸骨端、肋软骨肋骨端的厚度等6个指标的胶片测量值和手术中实体测量值进行比较,并做统计学分析。结果:①对已打印的胶片进行测量,胶片上所示10 cm和5 cm比例尺与直尺的实际尺寸相等;②胶片上肋软骨影像的 6组测量值和手术中的肋软骨实体测值对比,测量值差异无统计学意义。结论:基于DICOM协议下的打印技术可以实现肋软骨CT影像在胶片上的真实大小打印,术者从胶片中所获取的目标组织的形态数据可靠。Abstract: Objective: To explore the film printing technology for displaying the true size of costal cartilage on medical film. Methods: The CT images of costal cartilage of 31 patients were selected and processed 14×17 inches (35×43 cm), calculate the main image display area and 14×17 the scale between the actual image display areas on the film shall be made into physical scales of 10 cm and 5 cm in length. Print the film in 2×2. Four images are arranged in the grid, and the transverse or sagittal images of single rib cartilage are printed on a 5 cm physical scale; with 1×1 The grid is a single image layout, and the 3D images of all the front rib arches (including costal cartilage) are printed on a 10 cm physical scale. The film measurement values of six indicators, including the length of the ascending and transverse parts of the right sixth costal cartilage, the width and thickness of the transverse junction of the ascending part, the thickness of the sternal end of the costal cartilage and the rib end of the costal cartilage, were compared with the solid measurement values during the operation, and statistical analysis was made. Results: (1) The printed film was measured, and the 10 cm and 5 cm scales shown on the film were equal to the actual size of the ruler. (2) There was no significant difference between the measured values of six groups of costal cartilage images on film and the measured values of costal cartilage entities during surgery. Conclusion: The printing technology based on DICOM protocol can realize the real size printing of costal cartilage CT image on film. The morphological data of the target tissue obtained by the operator from the film are reliable.
