1. A system for acquiring images, the system comprising:
an imaging system configured to acquire images from a subject using ionizing radiation; and
a computer system configured to control the imaging system to:
deliver a series of doses of the ionizing radiation to the subject that includes at least a high dose of the ionizing radiation dose and a low dose of the ionizing radiation dose during an imaging session to acquire imaging data;
deliver more low doses of the ionizing radiation than high doses of ionizing radiation during the imaging session to acquire the imaging data to include a high frame rate of low dose data and a low frame rate of high dose data while interspersing the high doses of the ionizing radiation within the low doses of the ionizing radiation; and
generate at least angiographic images showing vessels of the subject using the high dose data and dynamic images of the subject showing contrast medium dynamics in the subject using the low dose data;
wherein the series of doses of the ionizing radiation delivers a total dose that is less than required to produce the at least the angiographic images of the subject and the dynamic images of the subject from the imaging data using two non-interleaved acquisition processes.
