In addition to a radiation source (6) attached to a C-arm 4, and in addition to a detector (7), a rotation angiography device (1) for the angiocardiography has an evaluation unit (8), which formulates models with low resolution from the projection images supplied by the detector (7) for the moving object to be examined, and which generates movement fields for the projection images generated by the detector (7) on the basis of the model, so that movement-corrected projection images can be calculated from the projection images, which can be used to formulate a three-dimensional high-resolution model of the object to be examined.

A triple three-way valve device comprises: a valve body (1) having a distal end and a proximal end, wherein the proximal end of the valve body (1) is connected with a control knob (2) that is radially rotatable relative to the valve body (1); and a valve rod (3) having a distal end and a proximal end, wherein the valve rod (3) is provided within the valve body (1) and is fixedly connected with the control knob (2). The distal end of the valve body (1) is connected with a seat body (4), which is connected with a plurality of liquid passages and a high pressure pipe passage; a selection member (5) provided at the distal end of the valve body (1), wherein, depending on the position of the control knob (2), the selection member (5) selects the communication relationships between the plurality of liquid passages of the seat body (4), the high pressure pipe passage and the valve rod. With the triple three-way valve device, angiocardiography surgery is simplified, and surgery safety and efficiency are improved.
