1. A medical imaging system comprising:
a multi-energy X-ray source operative to transmit X-rays through a patient, wherein the X-ray source is collimated to produce a diverging beam of radiation;
a detector operative to receive the X-ray energy of the X-rays after having passed through the patient, wherein the detector includes detector pixels arranged in at least one row; and
a processing system programmed to perform a scan of the patient based on a time delayed summation (TDS) frequency and to generate at least two images of a patient bone corresponding to the multi-energy levels of the multi-energy X-ray source;
wherein the processing system is further programmed to determine a patient bone mineral density (BMD) based on the at least two images, and
wherein the TDS frequency is based on an initial height of the patient bone with respect to an X-ray source plane, and
wherein the initial height of the patient bone with respect to the X-ray source plane is an estimate based on historical data of the patient bone or objects similar to the patient bone, and
wherein the processing system is further programmed to determine a new TDS shift frequency if a new height of the patient bone based on a beam angle and an overlap of adjacent images is different than the initial height of the patient bone.
