DOI: 10.1002/acm2.13840

Abstract: Abstract Image‐guided adaptive intracavitary/interstitial brachytherapy (IC/IS IGABT) has exhibited superior dosimetry advantage and local control for locally advanced cervical cancer (LACC). Our group designed a type of cylindrical three‐dimensional (3D) printed vaginal template combining an… read more here.

DOI: 10.1002/mp.70103

Abstract: Generating three‐dimensional (3D) ultrasound (US) data from conventional two‐dimensional (2D) freehand acquisitions typically necessitates external tracking systems to ascertain probe positioning. However, these hardware‐based solutions often present practical challenges, including substantial cost, increased setup complexity,… read more here.
