Purpose: Medical devices are the most budgeted items in hospitals. For this reason, the decision to buy a medical device is one of the critical decisions. In this study, the selection problem of echocardiography device planned to be taken to a cardiology department in a public hospital was discussed. Methods: Criteria affecting echocardiography device selection and available alternative devices were determined by reviewing the relevant literature and taking the opinions of three physicians specializing in cardiology. After the selection criteria were determined, the criteria were weighted by the Analytic Hierarchy Process (AHP) method and the best alternative was determined by sorting the alternatives by TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. Results: The priorities of the alternatives determined for the selection problem of the echocardiography device were found to be %48 for B, %29 for A, and %23 for C, according to the AHP method. With the TOPSIS method, the ideal distance (Si *), negative ideal distance (Si-) and the ideal solution relative (Ci *) values of each decision point were found to be 0, 0.124287 and 1 for B, respectively. Conclusion: According to the method of AHP and TOPSIS, device B is the first alternative.
