  Coleman-ICEC presentation-10.02.2023.pdf
  - a) A. ICEC Goals
  - b) B. Status of RT in LMICs
    
    Challenges for LINACs in LMICs
    
    Generally accepted design features of a LINAC for challenging environments based on prior workshops
    a. Low overall cost
    b. Robust (not susceptible to breakdown of hardware or software)
    c. Ease of operation by radiation therapy technologists (RTTs)
    d. Modular for ease of repairs by medical physicists or engineers and for upgrading
    e. Insensitive to power failures
    f. Low power requirement
    g. Low heat production
    h. High level internet connectivity (fail-proof) for local operation as well as remote QA, treatment planning, system fault diagnosis

  Discussion of Key Design Considerations from LMICs
  
  a. Ability to provide radiation treatments with routine and advanced techniques; what do you consider essential: 3D-CRT, IMRT, VMAT, SBRT, SRS?
  b. Is single photon energy (6 MV), a dose rate of 600 cGy/min and a 0.1 cm beam spot size on target as selected acceptable?
  c. Are multi-leaf collimators (MLCs) breaking down a major problem?
  d. Cone-beam CT on the RT system?
  e. Higher level diagnostic imaging capability on the RT system (such a diagnostic CT scanner for adaptive replanning or for pure diagnostic imaging when the RT system is not being used for patient treatments?)
  f. Remote treatment planning as well as full capability for treatment planning locally?
  g. Remote RT system diagnostics and repair?
  
  Other?
