“…motorized orbital drive, and a computer control system for image acquisition and 3-D reconstruction. [11][12][13] Image acquisition involved 200 projections across the maximum gantry arc (y tot ¼ 178 ) at a nominal rotation speed of 3 /s (although a faster orbital drive-up to 18 /s-is under development). Tomosynthesis acquisition involved the collection of projections across a limited arc (20 -90 ) with the total orbital extent denoted y tot (Fig.…”

“…In recent several years, a FPD technology, especially a dynamic imaging technology, has shown a great progress [1][2][3]. We'd reported on a prototype digital radiography (DR) system using a 25x20cm with a 127 m pixel pitch FPD [4] and a clinical prototype system using the large-area FPD [5,6].…”

A novel angiography system with cone-beam reconstruction using a large-area flat panel detector (FPD), with 40x30cm active area and 2048x1536 matrixes with a 194 m pixel pitch, has been developed. We present results on a basic performance, spatial resolution and contrast detectability obtained on this angiography system with cone-beam function using the FPD, and compare with a conventional angiography system with an image intensifier (I.I.) and charge-coupled device (CCD) camera.We'd achieved a fast acquisition, 15 seconds as for a subtraction mode by rotating a ceiling suspended C-arm at a speed of 40 degrees per second, and ensured a large reconstructed columnar volume, 250mmx180mm, by using the large-area detector. As a result of the evaluation, the 3D image acquired from the FPD system has a high spatial resolution with no distortion and good contrast detectability.

“…The FPD technology, especially dynamic imaging technology has shown great progress in the last several years [1,2,3], we have also reported a developed DR system using a FPD, 25x20cm with 127um pixel pitch in medical imaging 2001 [4]. A clinical prototype Digital Radiography (DR) system to compare with a conventional Image Intensifier and Charge-Coupled Device camera (I.I.-CCD) type DR system using a large-area Flat Panel Detector (FPD), a 40x30cm with 194um pixel pitch, has been reported in medical imaging 2002 [5].…”

We developed prototype Digital Subtraction Angiography (DSA) System with a new large area FPD. Dynamic range, MTF, Contrast ratio and line noise were much improved. The improved FPD is a scintillator-type detector, and has a 40 x 30 cm active area, 2048 x 1536 matrix with 194um pixel pitch. The Prototype DSA system has two x-ray detectors, the FPD and the I.I.-CCD camera, and we can choose them on demand. All images captured from both detectors at 3 frames/sec in DSA mode and 30 frames/sec in Fluoroscopy mode are forwarded to our image-processing unit. We applied the new DSA system to more than 150 studies and compared the results with images from the I.I.-CCD. In DSA mode, FPD System, which has a wide dynamic range, large detecting area, and good contrast ratio yielded superior angiographic images compared with the I.I-CCD system. In Fluoroscopy mode, we improved line noise and increased the contrast of catheters and guide wires with a new image processing technique. With these improvements, the image quality of the FPD System is superior to the I.I.-CCD system at the exposure range of over 2uR/frame (17.4 nGy/frame).
