A medical imaging system comprising: an X-ray source operative to transmit X-rays through an object, 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 object, wherein the detector includes detector pixels arranged in at least one row; and a processing system programmed to: select an initial height of the object with respect to the X-ray source plane; determine an initial time delayed summation shift frequency based on the initial height, wherein the TDS shift frequency is a frequency at which a content of each detector pixel counter is shifted to a neighboring detector pixel counter; perform a first scan of the object based on the TDS shift frequency; determine a new height of the object based on a beam angle and an overlap of adjacent images; determine a new TDS shift frequency based on the new height of the object if the initial height and the new height are not substantially same and perform a second scan of the object based on the new TDS shift frequency; and generate an image of the object based on detected X-ray energy at the X-ray detector based on the first scan and the second scan. an X-ray source operative to transmit X-rays through an object, 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 object, wherein the detector includes detector pixels arranged in at least one row; and a processing system programmed to: select an initial height of the object with respect to the X-ray source plane; determine an initial time delayed summation shift frequency based on the initial height, wherein the TDS shift frequency is a frequency at which a content of each detector pixel counter is shifted to a neighboring detector pixel counter; perform a first scan of the object based on the TDS shift frequency; determine a new height of the object based on a beam angle and an overlap of adjacent images; determine a new TDS shift frequency based on the new height of the object if the initial height and the new height are not substantially same and perform a second scan of the object based on the new TDS shift frequency; and generate an image of the object based on detected X-ray energy at the X-ray detector based on the first scan and the second scan. select an initial height of the object with respect to the X-ray source plane; determine an initial time delayed summation shift frequency based on the initial height, wherein the TDS shift frequency is a frequency at which a content of each detector pixel counter is shifted to a neighboring detector pixel counter; perform a first scan of the object based on the TDS shift frequency; determine a new height of the object based on a beam angle and an overlap of adjacent images; determine a new TDS shift frequency based on the new height of the object if the initial height and the new height are not substantially same and perform a second scan of the object based on the new TDS shift frequency; and generate an image of the object based on detected X-ray energy at the X-ray detector based on the first scan and the second scan.
