A method of optimized diagnosis and treatment of suspected myocardial infarctions is described. The patient having possible coronary artery disease is transferred to a treatment room with an imaging modality suitable for obtaining computed tomographic (CT)-like images. Such images are obtained as radiographic image data, with or without contrast agent, and used in the medical diagnosis. If minimally invasive therapy such as percutaneous transluminal coronal angioplasty (PTCA) is indicated, the patient is prepared for the procedure in the same room, and the procedure performed, where the imaging modality is used to obtain fluoroscopic images to guide the PTCA procedure, or to assess the results of the procedure. The imaging modality may be mounted to a first positioning robot, and a second robot may facilitate the positioning or movement of the patient.
